## Query parameters

- `page_size` integer
- `page_token` string

## Response `200`

Custom Connector Runtime.

- ConnectV1CustomConnectorRuntimeList — List of supported runtime languages for Custom Connector Plugin. The list defines the supported entries for confluent.custom.connect.plugin.runtime attribute in CustomConnectorPlugin object. Each entry also defines the set of supported java versions for that runtime which can be specified during connector provisioning via the confluent.custom.connect.plugin.java.version attribute. ## The Custom Connector Runtimes Model <SchemaDefinition schemaRef="#/components/schemas/connect.v1.CustomConnectorRuntime" />
  - `api_version` 'connect/v1', required — APIVersion defines the schema version of this representation of a resource.
  - `kind` 'CustomConnectorRuntimeList', required — Kind defines the object this REST resource represents.
  - `metadata` object, required — ListMeta describes metadata that resource collections may have
    - `first` string, uri, nullable — A link to the first page of results. If a response does not contain a first link, then direct navigation to the first page is not supported.
    - `last` string, uri, nullable — A link to the last page of results. If a response does not contain a last link, then direct navigation to the last page is not supported.
    - `prev` string, uri, nullable — A link to the previous page of results. If a response does not contain a prev link, then either there is no previous data or backwards traversal through the result set is not supported.
    - `next` string, uri, nullable — A link to the next page of results. If a response does not contain a next link, then there is no more data available.
    - `total_size` integer — Number of records in the full result set. This response may be paginated and have a smaller number of records.
  - `data` object[], required — A data property that contains an array of resource items. Each entry in the array is a separate resource.
    - `api_version` 'connect/v1' — APIVersion defines the schema version of this representation of a resource.
    - `kind` 'CustomConnectorRuntime' — Kind defines the object this REST resource represents.
    - `id` string, required — ID is the "natural identifier" for an object within its scope/namespace; it is normally unique across time but not space. That is, you can assume that the ID will not be reclaimed and reused after an object is deleted ("time"); however, it may collide with IDs for other object `kinds` or objects of the same `kind` within a different scope/namespace ("space").
    - `custom_connect_plugin_runtime_name` string — Name of the runtime that is being used while provisioning a custom connector. This corresponds to the property custom.connect.plugin.runtime in the connector configuration.
    - `runtime_ak_version` string — The underlying version of Apache Kafka which bundles the connect runtime
    - `supported_java_versions` string[] — List of supported Java versions
    - `product_maturity` string — The product maturity phase for the plugin runtime. EA (Early Access), GA (Generally Available), or Preview.
    - `end_of_life_at` string, date-time — End of Life date for the runtime
    - `description` string — Description of the runtime

## Other responses

- `400` — Bad Request
- `401` — The request lacks valid authentication credentials for this resource.
- `403` — The access credentials were considered insufficient to grant access
- `429` — Rate Limit Exceeded
- `500` — Oops, something went wrong!
