Connectors are {es} integrations that bring content from third-party data sources, which can be deployed on {ecloud} or hosted on your own infrastructure:
* To sync data using self-managed connectors, you need to deploy the {enterprise-search-ref}/build-connector.html[Elastic connector service] on your own infrastructure. This service runs automatically on Elastic Cloud for native connectors.
* The `service_type` parameter should reference a supported third-party service. See the available service types for {enterprise-search-ref}/native-connectors.html[native] and {enterprise-search-ref}/build-connector.html[self-managed] connectors. This can also reference the service type of your custom connector.
Creates a connector document in the internal index and initializes its configuration, filtering, and scheduling with default values. These values can be updated later as needed.
(Optional, string) Connector service type. Can reference Elastic-supported third-party services or a custom connector type. See the available service types for {enterprise-search-ref}/native-connectors.html[native] and {enterprise-search-ref}/build-connector.html[self-managed] connectors.
