# RabbitMQ Management HTTP API

## Introduction

Apart from this help page, all URIs will serve only resources of type `application/json`, and will require HTTP basic authentication (using the standard RabbitMQ user database). The default user is guest/guest.

Many URIs require the name of a virtual host as part of the path, since names only uniquely identify objects within a virtual host. As the default virtual host is called "`/`", this will need to be encoded as "`%2F`".

PUTing a resource creates it. The JSON object you upload must have certain mandatory keys (documented below) and may have optional keys. Other keys are ignored. Missing mandatory keys constitute an error.

Since bindings do not have names or IDs in AMQP we synthesise one based on all its properties. Since predicting this name is hard in the general case, you can also create bindings by POSTing to a factory URI. See the example below.

Many URIs return lists. Such URIs can have the query string parameters `sort` and `sort_reverse` added. `sort` allows you to select a primary field to sort by, and `sort_reverse` will reverse the sort order if set to `true`. The `sort` parameter can contain subfields separated by dots. This allows you to sort by a nested component of the listed items; it does not allow you to sort by more than one field. See the example below.

You can also restrict what information is returned per item with the `columns` parameter. This is a comma-separated list of subfields separated by dots. See the example below.

It is possible to disable the statistics in the GET requests and obtain just the basic information of every object. This reduces considerably the amount of data returned and the memory and resource consumption of each query in the system. For some monitoring and operation purposes, these queries are more appropriate. The query string parameter `disable_stats` set to `true` will achieve this.

Most of the GET queries return many fields per object. The second part of this guide covers those.

## rabbitmqadmin

While the HTTP API can be used directly (with `curl`, `xh` and similar tools), for most day-to-day operations the recommended option is rabbitmqadmin.

## Client Libraries

Client libraries for the HTTP API are available for many programming languages.

## Examples

A few quick examples for Windows and Unix, using the command line tool `curl`:

- Get a list of vhosts:

      :: Windows
      C:\> curl -i -u guest:guest http://localhost:15672/api/vhosts

      # Unix
      $ curl -i -u guest:guest http://localhost:15672/api/vhosts

      HTTP/1.1 200 OK
      cache-control: no-cache
      content-length: 196
      content-security-policy: default-src 'self'
      content-type: application/json
      date: Mon, 02 Sep 2019 07:51:49 GMT
      server: Cowboy
      vary: accept, accept-encoding, origin

      [{"cluster_state":{"rabbit@localhost":"running"},"description":"Default virtual host" ... (remainder elided)

- Get a list of channels, fast publishers first, restricting the info items we get back:

      :: Windows
      C:\> curl -i -u guest:guest "http://localhost:15672/api/channels?sort=message_stats.publish_details.rate&sort_reverse=true&columns=name,message_stats.publish_details.rate,message_stats.deliver_get_details.rate"

      # Unix
      $ curl -i -u guest:guest 'http://localhost:15672/api/channels?sort=message_stats.publish_details.rate&sort_reverse=true&columns=name,message_stats.publish_details.rate,message_stats.deliver_get_details.rate'

      HTTP/1.1 200 OK
      cache-control: no-cache
      content-length: 2
      content-security-policy: default-src 'self'
      content-type: application/json
      date: Mon, 02 Sep 2019 07:54:35 GMT
      server: Cowboy
      vary: accept, accept-encoding, origin

      [{"message_stats":{"publish_details":{"rate" ... (remainder elided)

- Create a new vhost:

      :: Windows
      C:\> curl -i -u guest:guest -H "content-type:application/json" ^
            -XPUT http://localhost:15672/api/vhosts/foo

      # Unix
      $ curl -i -u guest:guest -H "content-type:application/json" \
         -XPUT http://localhost:15672/api/vhosts/foo

      HTTP/1.1 201 Created
      content-length: 0
      content-security-policy: default-src 'self'
      date: Mon, 02 Sep 2019 07:55:24 GMT
      server: Cowboy
      vary: accept, accept-encoding, origin

  Note: you must specify `application/json` as the mime type.

  Note: the name of the object is not needed in the JSON object uploaded, since it is in the URI. As a virtual host has no properties apart from its name, this means you do not need to specify a body at all!

- Create a new exchange in the default virtual host:

      :: Windows
      C:\> curl -i -u guest:guest -H "content-type:application/json" ^
             -XPUT -d"{""type"":""direct"",""durable"":true}" ^
             http://localhost:15672/api/exchanges/%2F/my-new-exchange

      # Unix
      $ curl -i -u guest:guest -H "content-type:application/json" \
          -XPUT -d'{"type":"direct","durable":true}' \
          http://localhost:15672/api/exchanges/%2F/my-new-exchange

      HTTP/1.1 201 Created
      content-length: 0
      content-security-policy: default-src 'self'
      date: Mon, 02 Sep 2019 07:56:06 GMT
      server: Cowboy
      vary: accept, accept-encoding, origin

  Note: we never return a body in response to a PUT or DELETE, unless it fails.

- And delete it again:

      :: Windows
      C:\> curl -i -u guest:guest -H "content-type:application/json" ^
             -XDELETE http://localhost:15672/api/exchanges/%2F/my-new-exchange

      # Unix
      $ curl -i -u guest:guest -H "content-type:application/json" \
          -XDELETE http://localhost:15672/api/exchanges/%2F/my-new-exchange

      HTTP/1.1 204 No Content
      content-security-policy: default-src 'self'
      date: Mon, 02 Sep 2019 07:56:59 GMT
      server: Cowboy
      vary: accept, accept-encoding, origin

X |  |  |  | /api/exchanges | A list of all exchanges. Use pagination parameters to list exchanges.
X |  |  |  | /api/exchanges/vhost | A list of all exchanges in a given virtual host. Use pagination parameters to list exchanges.
X | X | X |  | /api/exchanges/vhost/name | An individual exchange. To PUT an exchange, you will need a body looking something like this:
    {"type":"direct","auto_delete":false,"durable":true,"internal":false,"arguments":{}}
The `type` key is mandatory; other keys are optional. When DELETEing an exchange you can add the query string parameter `if-unused=true`. This prevents the delete from succeeding if the exchange is bound to a queue or as a source to another exchange.
X |  |  |  | /api/exchanges/vhost/name/bindings/source | A list of all bindings in which a given exchange is the source.
X |  |  |  | /api/exchanges/vhost/name/bindings/destination | A list of all bindings in which a given exchange is the destination.
|  |  | X | /api/exchanges/vhost/name/publish | Publish a message to a given exchange. You will need a body looking something like:
    {"properties":{},"routing_key":"my key","payload":"my body","payload_encoding":"string"}
All keys are mandatory. The `payload_encoding` key should be either "string" (in which case the payload will be taken to be the UTF-8 encoding of the payload field) or "base64" (in which case the payload field is taken to be base64 encoded). If the message is published successfully, the response will look like:
    {"routed": true}
`routed` will be true if the message was sent to at least one queue. Please note that the HTTP API is not ideal for high performance publishing; the need to create a new TCP connection for each message published can limit message throughput compared to AMQP or other protocols using long-lived connections.
X |  |  |  | /api/queues | A list of all queues across all virtual hosts returning a reduced set of fields. Use pagination parameters to list queues, otherwise this endpoint can produce very large JSON responses and waste a lot of bandwidth and CPU resources. Default page size is 100, maximum supported page size is 500. The parameter `enable_queue_totals=true` can be used in combination with the `disable_stats=true` parameter to return a reduced set of fields and significantly reduce the amount of data returned by this endpoint. That in turn can significantly reduce CPU and bandwidth footprint of such requests.
X |  |  |  | /api/queues/detailed | A list of all queues containing all available information about the queues (over 50 fields per queue). Use pagination parameters to list queues, otherwise this endpoint can produce very large JSON responses and waste a lot of bandwidth and CPU resources. Default page size is 100, maximum supported page size is 500.
X |  |  |  | /api/queues/vhost | A list of all queues in the given virtual host containing all available information about the queues (over 50 fields per queue).. Use pagination parameters to list queues, otherwise this endpoint can produce very large JSON responses and waste a lot of bandwidth and CPU resources. Default page size is 100, maximum supported page size is 500.
X | X | X |  | /api/queues/vhost/name | An individual queue. To PUT a queue, you will need a body looking something like this:
    {"auto_delete":false,"durable":true,"arguments":{},"node":"rabbit@node.hostname"}
All keys are optional. When DELETEing a queue you can add the query string parameters `if-empty=true` and / or `if-unused=true`. These prevent the delete from succeeding if the queue contains messages, or has consumers, respectively.
X |  |  |  | /api/queues/vhost/name/bindings | A list of all bindings on a given queue.
|  | X |  | /api/queues/vhost/name/contents | Contents of a queue. DELETE to purge. Note you can't GET this.
|  |  | X | /api/queues/vhost/name/actions | Actions that can be taken on a queue. Currently no actions are supported.
|  |  | X | /api/queues/vhost/name/get | Get messages from a queue. (This is not an HTTP GET as it will alter the state of the queue.) You should post a body looking like:
    {"count":5,"ackmode":"ack_requeue_true","encoding":"auto","truncate":50000}
`count` controls the maximum number of messages to get. You may get fewer messages than this if the queue cannot immediately provide them. `ackmode` determines whether the messages will be removed from the queue. If ackmode is ack_requeue_true or reject_requeue_true they will be requeued - if ackmode is ack_requeue_false or reject_requeue_false they will be removed. `encoding` must be either "auto" (in which case the payload will be returned as a string if it is valid UTF-8, and base64 encoded otherwise), or "base64" (in which case the payload will always be base64 encoded). If `truncate` is present it will truncate the message payload if it is larger than the size given (in bytes). `truncate` is optional; all other keys are mandatory. Please note that the get path in the HTTP API is intended for diagnostics etc - it does not implement reliable delivery and so should be treated as a sysadmin's tool rather than a general API for messaging.
X |  |  |  | /api/bindings | A list of all bindings. Use pagination parameters to list bindings, otherwise this endpoint can produce very large JSON responses and waste a lot of bandwidth and CPU resources. Default page size is 100, maximum supported page size is 500.
X |  |  |  | /api/bindings/vhost | A list of all bindings in a given virtual host. Use pagination parameters to list bindings, otherwise this endpoint can produce very large JSON responses and waste a lot of bandwidth and CPU resources. Default page size is 100, maximum supported page size is 500.
X |  |  | X | /api/bindings/vhost/e/exchange/q/queue | A list of all bindings between an exchange and a queue. Remember, an exchange and a queue can be bound together many times! To create a new binding, POST to this URI. Request body should be a JSON object optionally containing two fields, `routing_key` (a string) and `arguments` (a map of optional arguments):
    {"routing_key":"my_routing_key", "arguments":{"x-arg": "value"}}
All keys are optional. The response will contain a `Location` header telling you the URI of your new binding.
X |  | X |  | /api/bindings/vhost/e/exchange/q/queue/props | An individual binding between an exchange and a queue. The props part of the URI is a "name" for the binding composed of its routing key and a hash of its arguments. props is the field named "properties_key" from a bindings listing response.
X |  |  | X | /api/bindings/vhost/e/source/e/destination | A list of all bindings between two exchanges, similar to the list of all bindings between an exchange and a queue, above. To create a new binding, POST to this URI. Request body should be a JSON object optionally containing two fields, `routing_key` (a string) and `arguments` (a map of optional arguments):
    {"routing_key":"my_routing_key", "arguments":{"x-arg": "value"}}
All keys are optional. The response will contain a `Location` header telling you the URI of your new binding.
X |  | X |  | /api/bindings/vhost/e/source/e/destination/props | An individual binding between two exchanges. Similar to the individual binding between an exchange and a queue, above.
X |  |  |  | /api/vhosts | A list of all vhosts. Pagination: default page size is 100, maximum supported page size is 500.
X | X | X |  | /api/vhosts/name | An individual virtual host. As a virtual host usually only has a name, you do not need an HTTP body when PUTing one of these. To set metadata on creation, provide a body like the following:
    {"description":"virtual host description", "tags":"accounts,production"}
`tags` is a comma-separated list of tags. These metadata fields are optional. To enable / disable tracing, provide a body looking like:
    {"tracing":true}
X |  |  |  | /api/vhosts/name/permissions | A list of all permissions for a given virtual host.
X |  |  |  | /api/vhosts/name/topic-permissions | A list of all topic permissions for a given virtual host.
|  | X | X | /api/vhosts/name/deletion/protection | Enables (when used with POST) or disabled (with DELETE) deletion protection for the virtual host.
|  |  | X | /api/vhosts/name/start/node | Starts virtual host name on node node.
X |  |  |  | /api/users/ | A list of all users.
X |  |  |  | /api/users/without-permissions | A list of users that do not have access to any virtual host.
|  |  | X | /api/users/bulk-delete | Bulk deletes a list of users. Request body must contain the list:
    {"users" : ["user1", "user2", "user3"]}
X | X | X |  | /api/users/name | An individual user. To PUT a user, you will need a body looking something like this:
    {"password":"secret","tags":"administrator"}
or:
    {"password_hash":"2lmoth8l4H0DViLaK9Fxi6l9ds8=", "tags":["administrator"]}
The `tags` key is mandatory. Either `password` or `password_hash` can be set. If neither are set the user will not be able to log in with a password, but other mechanisms like client certificates may be used. Setting `password_hash` to `""` will ensure the user cannot use a password to log in. `tags` is a comma-separated list of tags for the user. Currently recognised tags are `administrator`, `monitoring` and `management`. `password_hash` must be generated using the algorithm described here. You may also specify the hash function being used by adding the `hashing_algorithm` key to the body. Currently recognised algorithms are `rabbit_password_hashing_sha256`, `rabbit_password_hashing_sha512`, and `rabbit_password_hashing_md5`.

X |  |  |  | /api/health/checks/alarms | Responds a 200 OK if there are no alarms in effect in the cluster, otherwise responds with a 503 Service Unavailable. Relevant documentation guide: Resource Alarms
X |  |  |  | /api/health/checks/local-alarms | Responds a 200 OK if there are no local alarms in effect on the target node, otherwise responds with a 503 Service Unavailable. Relevant documentation guide: Resource Alarms
X |  |  |  | /api/health/checks/certificate-expiration/within/unit | Checks the expiration date of every certificate found in the PEM certificate bundles used by all TLS-enabled listeners on the node, regardless of the "type" of the certificate (leaf/server identity, intermediary or any CA). Responds a 200 OK if all certificates are valid (have not expired), otherwise responds with a 503 Service Unavailable. This health assumes that All certificates included in the PEM bundles on the nodes are relevant to RabbitMQ clients, plugins or encrypted inter-node communication Expired certificates is not a normal operating condition and any expired certificate found must be reported with a check failure Do not use this health check if some of these assumptions are not true. Valid units: days, weeks, months, years. The value of the within argument is the number of units. So, when within is 2 and unit is "months", the expiration period used by the check will be the next two months. Relevant documentation guides: TLS, Encrypted Inter-node Communication
X |  |  |  | /api/health/checks/port-listener/port | Responds a 200 OK if there is an active listener on the given port, otherwise responds with a 503 Service Unavailable.
X |  |  |  | /api/health/checks/protocol-listener/protocols | Responds a 200 OK if all given protocols have active listeners, otherwise responds with a 503 Service Unavailable. Multiple protocols may be provided by separating the names with commas. Valid protocol names are: amqp091, amqp10, mqtt, stomp, web-mqtt, web-stomp.
X |  |  |  | /api/health/checks/virtual-hosts | Responds a 200 OK if all virtual hosts and running on the target node, otherwise responds with a 503 Service Unavailable.
X |  |  |  | /api/health/checks/node-is-quorum-critical | Checks if there are quorum queues with minimum online quorum (queues that would lose their quorum and availability if the target node is shut down). Responds a 200 OK if there are no such quorum queues, otherwise responds with a 503 Service Unavailable. Relevant documentation guide: Quorum Queues
X |  |  |  | /api/health/checks/is-in-service | Responds a 200 OK if the target node is booted, running, and ready to serve clients, otherwise responds with a 503 Service Unavailable. If the target node is being drained for maintenance then this check returns 503 Service Unavailable.
X |  |  |  | /api/health/checks/below-node-connection-limit | Responds a 200 OK if the target node has fewer connections to the AMQP and AMQPS ports than the configured maximum, otherwise responds with a 503 Service Unavailable.
X |  |  |  | /api/health/checks/ready-to-serve-clients | Responds a 200 OK if the target node is ready to serve clients, otherwise responds with a 503 Service Unavailable. This check combines: /api/health/checks/is-in-service /api/health/checks/protocol-listener/amqp or /api/health/checks/protocol-listener/amqps /api/health/checks/below-node-connection-limit So this check will only return 200 OK if the target node is in service, an AMQP or AMQPS listener is available and the target node has fewer active AMQP and AMQPS connections that its configured limit.
X |  |  |  | /api/vhost-limits | Lists per-vhost limits for all vhosts.

    {"value": 100}
. Example request:
    curl -4u 'guest:guest' -H 'content-type:application/json' -X PUT localhost:15672/api/vhost-limits/my-vhost/max-connections -d '{"value": 50}'
Relevant documentation guide: Virtual Hosts

## HTTP API Stats

Most of the GET requests you can issue to the HTTP API return JSON objects with a large number of keys. While a few of these keys represent things you set yourself in a PUT request or AMQP command (e.g. queue durability or arguments), most of them represent statistics to do with the object in question. This page attempts to document them.

It should be read in conjunction with the manual page for `rabbitmqctl` (see your installation if on Unix / Linux, or the RabbitMQ website for the latest version). Any field which can be returned by a command of the form `rabbitmqctl list_something` will also be returned in the equivalent part of the HTTP API, so all those keys are not documented here. However, the HTTP API also adds a lot of extra fields which are not available in `rabbitmqctl`.

## _details objects

Many fields represent a count of some kind: queue length, messages acknowledged, bytes received and so on. Such absolute counts returned by the HTTP API will often have a corresponding `_details` object which offers information on how this count has changed. So for example, from a queue:

        "messages": 123619,
        "messages_details": {
          "avg": 41206.333333333336,
          "avg_rate": 1030.1583333333333,
          "rate": 24723.8,
          "samples": [
            {
              "sample": 123619,
              "timestamp": 1400680560000
            },
            {
              "sample": 0,
              "timestamp": 1400680500000
            },
            {
              "sample": 0,
              "timestamp": 1400680440000
            }
          ]
        }

Here we have a `messages` count (the total messages in the queue), with some additional data:

`avg` | The average value for the requested time period (see below).
`avg_rate` | The average rate for the requested time period.
`rate` | How much the count has changed per second in the most recent sampling interval.
`samples` | Snapshots showing how the value has changed over the requested time period.

`avg`, `avg_rate` and `samples` will only appear if you request a specific time period by appending query parameters to the URL. To do this you need to set an age and an increment for the samples you want. The end of the range returned will always correspond to the present.

Different types of data take different query parameters to return samples, as in the following table. You can specify more than one set of parameters if the resource you are requesting can generate more than one type of sample (for example, queues can return message rates and queue lengths).

Messages sent and received | `msg_rates_age` / `msg_rates_incr`
Bytes sent and received | `data_rates_age` / `data_rates_incr`
Queue lengths | `lengths_age` / `lengths_incr`
Node statistics (e.g. file descriptors, disk space free) | `node_stats_age` / `node_stats_incr`

For example, appending `?lengths_age=3600&lengths_incr=60` will return the last hour's data on queue lengths, with a sample for every minute.

## message_stats objects

Many objects (including queues, exchanges and channels) will return counts of messages passing through them. These are included in a `message_stats` object (which in turn will contain `_details` objects for each count, as described above).

These can contain:

`publish` | Count of messages published.
`publish_in` | Count of messages published "in" to an exchange, i.e. not taking account of routing.
`publish_out` | Count of messages published "out" of an exchange, i.e. taking account of routing.
`confirm` | Count of messages confirmed.
`deliver` | Count of messages delivered in acknowledgement mode to consumers.
`deliver_no_ack` | Count of messages delivered in no-acknowledgement mode to consumers.
`get` | Count of messages delivered in acknowledgement mode in response to basic.get.
`get_no_ack` | Count of messages delivered in no-acknowledgement mode in response to basic.get.
`deliver_get` | Sum of all four of the above.
`redeliver` | Count of subset of messages in `deliver_get` which had the redelivered flag set.
`drop_unroutable` | Count of messages dropped as unroutable.
`return_unroutable` | Count of messages returned to the publisher as unroutable.

Only fields for which some activity has taken place will appear.

## Detailed message stats objects

In addition, queues, exchanges and channels can return a breakdown of message stats for each of their neighbours (i.e. adjacent objects in the chain: channel -> exchange -> queue -> channel). This will only happen if the `rates_mode` configuration item has been switched to `detailed` from its default of `basic`.

As this possibly constitutes a large quantity of data, it is also only returned when querying a single channel, queue or exchange rather than a list. Note also that the default sample retention policy means that these detailed message stats do not retain historical data for more than a few seconds.

The detailed message stats objects have different names depending on where they are (documented below). Each set of detailed stats consists of a list of objects with two fields, one identifying the partner object and one `stats` which is a message_stats object as described above.

For example, from a queue:

      "incoming": [
        {
          "stats": {
            "publish": 352593,
            "publish_details": {
              "rate": 100.2
            }
          },
          "exchange": {
            "name": "my-exchange",
            "vhost": "/"
          }
        }
        {
          "stats": {
            "publish": 543784,
            "publish_details": {
              "rate": 54.6
            }
          },
          "exchange": {
            "name": "amq.topic",
            "vhost": "/"
          }
        }
      ],

This queue is currently receiving messages from two exchanges: 100.2 msg/s from "my-exchange" and 54.6 msg/s from "amq.topic".

## Pagination Parameters

The pagination can be applied to the endpoints that list

- queues
- exchanges
- connections
- channels

Without pagination, these endpoints can produce very large JSON responses and waste a lot of bandwidth and CPU resources.

Default page size is 100, maximum supported page size is 500.

Below are the query parameters that can be used.

Parameter Name
Data Type
Description
`page` | Positive integer | Page number
`page_size` | Positive integer | Number of elements for page (default value: 100, maximum supported value: 500)
`name` | String | Filter by name, for example queue name, exchange name etc.
`use_regex` | Boolean | Enables regular expression for the param name

Examples:

`http://localhost:15672/api/queues?page=1&page_size=50` | Fetches the first queue page with 50 elements
`http://localhost:15672/api/queues/my-vhost?page=1&page_size=100&name=&use_regex=false&pagination=true` | Filter the first queues page for the virtual host "my-vhost"
`http://localhost:15672/api/exchanges?page=1&page_size=100&name=%5Eamq&use_regex=true&pagination=true` | Filter the first exchanges page, 100 elements, with named filtered using the regular expression "^amq"
