Experimental REST API Reference
===============================

Airflow exposes an REST API. It is available through the webserver. Endpoints are
available at ``/api/experimental/``.

.. warning::

  This REST API is deprecated since version 2.0. Please consider using :doc:`the stable REST API <stable-rest-api-ref>`.
  For more information on migration, see `UPDATING.md <https://github.com/apache/airflow/blob/master/UPDATING.md>`_

.. versionchanged:: 2.0

  The experimental REST API is disabled by default. To restore these APIs while migrating to
  the stable REST API, set ``enable_experimental_api`` option in ``[api]`` section to ``True``.

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, you should set parameter ``"replace_microseconds"`` to ``"false"`` (boolean as string).

  The 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' \
        --header 'Cache-Control: no-cache' \
        --header 'Content-Type: application/json' \
        --data '{"conf":"{\"key\":\"value\"}"}'

  **Trigger DAG with milliseconds precision, example:**

  .. code-block:: bash

    curl -X POST  \
        'http://localhost:8080/api/experimental/dags/<DAG_ID>/dag_runs' \
        --header 'Content-Type: application/json' \
        --header 'Cache-Control: no-cache' \
        --data '{"replace_microseconds":"false"}'

.. 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.
