Slack Connection
================

The Slack connection type enables Slack Integrations.

Authenticating to Slack
-----------------------

Authenticate to Slack using a `Slack API token
<https://slack.com/help/articles/215770388-Create-and-regenerate-API-tokens>`_.

Default Connection IDs
----------------------

The SlackHook and SlackAPIOperator use ``slack_default`` by default.

Configuring the Connection
--------------------------

Password (optional)
    Specify the Slack API token.

When specifying the connection in environment variable you should specify
it using URI syntax.

Note that all components of the URI should be URL-encoded.

For example:

.. code-block:: bash

   export AIRFLOW_CONN_SLACK_DEFAULT='slack://:token@'
