Community Providers

How-to creating a new community provider

This document gathers the necessary steps to create a new community provider and also guidelines for updating the existing ones. You should be aware that providers may have distinctions that may not be covered in this guide. The sequence described was designed to meet the most linear flow possible in order to develop a new provider.

Another recommendation that will help you is to look for a provider that works similar to yours. That way it will help you to set up tests and other dependencies.

First, you need to set up your local development environment. See Contribution Quick Start if you did not set up your local environment yet. We recommend using breeze to develop locally. This way you easily be able to have an environment more similar to the one executed by GitHub CI workflow.


Using the code above you will set up Docker containers. These containers your local code to internal volumes. In this way, the changes made in your IDE are already applied to the code inside the container and tests can be carried out quickly.

In this how-to guide our example provider name will be <NEW_PROVIDER>. When you see this placeholder you must change for your provider name.

Initial Code and Unit Tests

Most likely you have developed a version of the provider using some local customization and now you need to transfer this code to the Airflow project. Below is described all the initial code structure that the provider may need. Understand that not all providers will need all the components described in this structure. If you still have doubts about building your provider, we recommend that you read the initial provider guide and open a issue on GitHub so the community can help you.

├── providers/<NEW_PROVIDER>/

    ├── sensors/
       └── test_<NEW_PROVIDER>.py
    └── transfers/
        └── test_<NEW_PROVIDER>.py

Considering that you have already transferred your provider’s code to the above structure, it will now be necessary to create unit tests for each component you created. The example below I have already set up an environment using breeze and I’ll run unit tests for my Hook.

An important part of building a new provider is the documentation. Some steps for documentation occurs automatically by pre-commit see Installing pre-commit guide

Files automatically updated by pre-commit:

  • INSTALL in provider

Files automatically created when the provider is released:

  • docs/apache-airflow-providers-<NEW_PROVIDER>/commits.rst

  • /airflow/providers/<NEW_PROVIDER>/CHANGELOG

There is a chance that your provider’s name is not a common English word. In this case is necessary to add it to the file docs/spelling_wordlist.txt. This file begin with capitalized words and lowercase in the second block.

<NEW_PROVIDER> (new line)
<NEW_PROVIDER> (new line)

Add your provider dependencies into provider.yaml under dependencies key.. If your provider doesn’t have any dependency add a empty list.

In the docs/apache-airflow-providers-<NEW_PROVIDER>/connections.rst:

  • add information how to configure connection for your provider.

In the docs/apache-airflow-providers-<NEW_PROVIDER>/operators/<NEW_PROVIDER>.rst:

  • add information how to use the Operator. It’s important to add examples and additional information if your Operator has extra-parameters.

    .. _howto/operator:NewProviderOperator:
    Use the :class:`~airflow.providers.<NEW_PROVIDER>.operators.NewProviderOperator` to do something
    amazing with Airflow!
    Using the Operator
    The NewProviderOperator requires a ``connection_id`` and this other awesome parameter.
    You can see an example below:
    .. exampleinclude:: /../../airflow/providers/<NEW_PROVIDER>/example_dags/example_<NEW_PROVIDER>.py
        :language: python
        :start-after: [START howto_operator_<NEW_PROVIDER>]
        :end-before: [END howto_operator_<NEW_PROVIDER>]

In the docs/apache-airflow-providers-new_provider/index.rst:

  • add all information of the purpose of your provider. It is recommended to check with another provider to help you complete this document as best as possible.

In the airflow/providers/<NEW_PROVIDER>/provider.yaml add information of your provider:

package-name: apache-airflow-providers-<NEW_PROVIDER>

Defining your own connection types

You only need to add connection-types in case you have some hooks that have customized UI behavior. However, it is only supported for Airflow 2.2.0. If your providers are also targeting Airflow below 2.2.0 you should provide the deprecated hook-class-names array. The connection-types array allows for optimization of importing of individual connections and while Airflow 2.2.0 is able to handle both definition, the connection-types is recommended.

For more information see Custom connection types

After changing and creating these files you can build the documentation locally. The two commands below will serve to accomplish this. The first will build your provider’s documentation. The second will ensure that the main Airflow documentation that involves some steps with the providers is also working.

breeze build-docs --package-filter apache-airflow-providers-<NEW_PROVIDER>

Optional provider features

New in version 2.3.0: This feature is available in Airflow 2.3+.

Some providers might provide optional features, which are only available when some packages or libraries are installed. Such features will typically result in ImportErrors; however, those import errors should be silently ignored rather than pollute the logs of Airflow with false warnings. False warnings are a very bad pattern, as they tend to turn into blind spots, so avoiding false warnings is encouraged. However, until Airflow 2.3, Airflow had no mechanism to selectively ignore “known” ImportErrors. So Airflow 2.1 and 2.2 silently ignored all ImportErrors coming from providers with actually lead to ignoring even important import errors - without giving the clue to Airflow users that there is something missing in provider dependencies.

Using Providers with dynamic task mapping

Airflow 2.3 added Dynamic Task Mapping and it added the possibility of assigning a unique key to each task. Which means that when such dynamically mapped task wants to retrieve a value from XCom (for example in case an extra link should calculated) it should always check if the ti_key value passed is not None an only then retrieve the XCom value using XCom.get_value. This allows to keep backwards compatibility with earlier versions of Airflow.

Typical code to access XCom Value in providers that want to keep backwards compatibility should look similar to this (note the if ti_key is not None: condition).

def get_link(
    operator: BaseOperator,
    dttm: datetime | None = None,
    ti_key: "TaskInstanceKey" | None = None,
    if ti_key is not None:
        job_ids = XCom.get_value(key="job_id", ti_key=ti_key)
        assert dttm is not None
        job_ids = XCom.get_one(
    if not job_ids:
        return None
    if len(job_ids) < self.index:
        return None
    job_id = job_ids[self.index]
    return BIGQUERY_JOB_DETAILS_LINK_FMT.format(job_id=job_id)

Having sensors return XCOM values

In Airflow 2.3, sensor operators will be able to return XCOM values. This is achieved by returning an instance of the PokeReturnValue object at the end of the poke() method:

from airflow.sensors.base import PokeReturnValue

class SensorWithXcomValue(BaseSensorOperator):
    def poke(self, context: Context) -> Union[bool, PokeReturnValue]:
        # ...
        is_done = ...  # set to true if the sensor should stop poking.
        xcom_value = ...  # return value of the sensor operator to be pushed to XCOM.
        return PokeReturnValue(is_done, xcom_value)

To implement a sensor operator that pushes a XCOM value and supports both version 2.3 and pre-2.3, you need to explicitly push the XCOM value if the version is pre-2.3.

    from airflow.sensors.base import PokeReturnValue
except ImportError:
    PokeReturnValue = None

class SensorWithXcomValue(BaseSensorOperator):
    def poke(self, context: Context) -> bool:
        # ...
        is_done = ...  # set to true if the sensor should stop poking.
        xcom_value = ...  # return value of the sensor operator to be pushed to XCOM.
        if PokeReturnValue is not None:
            return PokeReturnValue(is_done, xcom_value)
            if is_done:
                context["ti"].xcom_push(key="xcom_key", value=xcom_value)
            return is_done
