REST API Reference
==================
Airflow exposes an REST API. It is available through the webserver. Endpoints are
available at ``/api/experimental/``.
.. warning::
The API structure is not stable. We expect the endpoint definitions to change.
Endpoints
---------
.. http:post:: /api/experimental/dags/<DAG_ID>/dag_runs
Creates a dag_run for a given dag id.
Note: If execution_date is not specified in the body, airflow by default creates only one DAG per second for a given DAG_ID.
In order to create multiple DagRun within one second, execution_date must be specified with the format "YYYY-mm-DDTHH:MM:SS.ssssss".
**Trigger DAG with config, example:**
.. code-block:: bash
curl -X POST \
http://localhost:8080/api/experimental/dags/<DAG_ID>/dag_runs \
-H 'Cache-Control: no-cache' \
-H 'Content-Type: application/json' \
-d '{"conf":"{\"key\":\"value\"}"}'
.. http:get:: /api/experimental/dags/<DAG_ID>/dag_runs
Returns a list of Dag Runs for a specific DAG ID.
.. http:get:: /api/experimental/dags/<string:dag_id>/dag_runs/<string:execution_date>
Returns a JSON with a dag_run's public instance variables. The format for the <string:execution_date> is expected to be "YYYY-mm-DDTHH:MM:SS", for example: "2016-11-16T11:34:15".
.. http:get:: /api/experimental/test
To check REST API server correct work. Return status 'OK'.
.. http:get:: /api/experimental/dags/<DAG_ID>/tasks/<TASK_ID>
Returns info for a task.
.. http:get:: /api/experimental/dags/<DAG_ID>/dag_runs/<string:execution_date>/tasks/<TASK_ID>
Returns a JSON with a task instance's public instance variables. The format for the <string:execution_date> is expected to be "YYYY-mm-DDTHH:MM:SS", for example: "2016-11-16T11:34:15".
.. http:get:: /api/experimental/dags/<DAG_ID>/paused/<string:paused>
'<string:paused>' must be a 'true' to pause a DAG and 'false' to unpause.
.. http:get:: /api/experimental/dags/<DAG_ID>/paused
Returns the paused state of a DAG
.. http:get:: /api/experimental/latest_runs
Returns the latest DagRun for each DAG formatted for the UI.
.. http:get:: /api/experimental/pools
Get all pools.
.. http:get:: /api/experimental/pools/<string:name>
Get pool by a given name.
.. http:post:: /api/experimental/pools
Create a pool.
.. http:delete:: /api/experimental/pools/<string:name>
Delete pool.
.. http:get:: /api/experimental/lineage/<DAG_ID>/<string:execution_date>/
Returns the lineage information for the dag.
