# Apache Airflow Python Client
# Overview
To facilitate management, Apache Airflow supports a range of REST API endpoints across its
objects.
This section provides an overview of the API design, methods, and supported use cases.
Most of the endpoints accept `JSON` as input and return `JSON` responses.
This means that you must usually add the following headers to your request:
```
Content-type: application/json
Accept: application/json
```
## Resources
The term `resource` refers to a single type of object in the Airflow metadata. An API is broken up by its
endpoint's corresponding resource.
The name of a resource is typically plural and expressed in camelCase. Example: `dagRuns`.
Resource names are used as part of endpoint URLs, as well as in API parameters and responses.
## CRUD Operations
The platform supports **Create**, **Read**, **Update**, and **Delete** operations on most resources.
You can review the standards for these operations and their standard parameters below.
Some endpoints have special behavior as exceptions.
### Create
To create a resource, you typically submit an HTTP `POST` request with the resource's required metadata
in the request body.
The response returns a `201 Created` response code upon success with the resource's metadata, including
its internal `id`, in the response body.
### Read
The HTTP `GET` request can be used to read a resource or to list a number of resources.
A resource's `id` can be submitted in the request parameters to read a specific resource.
The response usually returns a `200 OK` response code upon success, with the resource's metadata in
the response body.
If a `GET` request does not include a specific resource `id`, it is treated as a list request.
The response usually returns a `200 OK` response code upon success, with an object containing a list
of resources' metadata in the response body.
When reading resources, some common query parameters are usually available. e.g.:
```
v1/connections?limit=25&offset=25
```
|Query Parameter|Type|Description|
|---------------|----|-----------|
|limit|integer|Maximum number of objects to fetch. Usually 25 by default|
|offset|integer|Offset after which to start returning objects. For use with limit query parameter.|
### Update
Updating a resource requires the resource `id`, and is typically done using an HTTP `PATCH` request,
with the fields to modify in the request body.
The response usually returns a `200 OK` response code upon success, with information about the modified
resource in the response body.
### Delete
Deleting a resource requires the resource `id` and is typically executing via an HTTP `DELETE` request.
The response usually returns a `204 No Content` response code upon success.
## Conventions
- Resource names are plural and expressed in camelCase.
- Names are consistent between URL parameter name and field name.
- Field names are in snake_case.
```json
{
\"name\": \"string\",
\"slots\": 0,
\"occupied_slots\": 0,
\"used_slots\": 0,
\"queued_slots\": 0,
\"open_slots\": 0
}
```
### Update Mask
Update mask is available as a query parameter in patch endpoints. It is used to notify the
API which fields you want to update. Using `update_mask` makes it easier to update objects
by helping the server know which fields to update in an object instead of updating all fields.
The update request ignores any fields that aren't specified in the field mask, leaving them with
their current values.
Example:
```python
import requests
resource = requests.get("/resource/my-id").json()
resource["my_field"] = "new-value"
requests.patch("/resource/my-id?update_mask=my_field", data=json.dumps(resource))
```
## Versioning and Endpoint Lifecycle
- API versioning is not synchronized to specific releases of the Apache Airflow.
- APIs are designed to be backward compatible.
- Any changes to the API will first go through a deprecation phase.
# Trying the API
You can use a third party client, such as [curl](https://curl.haxx.se/), [HTTPie](https://httpie.org/),
[Postman](https://www.postman.com/) or [the Insomnia rest client](https://insomnia.rest/) to test
the Apache Airflow API.
Note that you will need to pass credentials data.
For e.g., here is how to pause a DAG with [curl](https://curl.haxx.se/), when basic authorization is used:
```bash
curl -X PATCH 'https://example.com/api/v1/dags/{dag_id}?update_mask=is_paused' \\
-H 'Content-Type: application/json' \\
--user \"username:password\" \\
-d '{
\"is_paused\": true
}'
```
Using a graphical tool such as [Postman](https://www.postman.com/) or [Insomnia](https://insomnia.rest/),
it is possible to import the API specifications directly:
1. Download the API specification by clicking the **Download** button at top of this document.
2. Import the JSON specification in the graphical tool of your choice.
- In *Postman*, you can click the **import** button at the top
- With *Insomnia*, you can just drag-and-drop the file on the UI
Note that with *Postman*, you can also generate code snippets by selecting a request and clicking on
the **Code** button.
## Enabling CORS
[Cross-origin resource sharing (CORS)](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS)
is a browser security feature that restricts HTTP requests that are
initiated from scripts running in the browser.
For details on enabling/configuring CORS, see
[Enabling CORS](https://airflow.apache.org/docs/apache-airflow/stable/security/api.html).
# Authentication
To be able to meet the requirements of many organizations, Airflow supports many authentication methods,
and it is even possible to add your own method.
If you want to check which auth backend is currently set, you can use
`airflow config get-value api auth_backends` command as in the example below.
```bash
$ airflow config get-value api auth_backends
airflow.api.auth.backend.basic_auth
```
The default is to deny all requests.
For details on configuring the authentication, see
[API Authorization](https://airflow.apache.org/docs/apache-airflow/stable/security/api.html).
# Errors
We follow the error response format proposed in [RFC 7807](https://tools.ietf.org/html/rfc7807)
also known as Problem Details for HTTP APIs. As with our normal API responses,
your client must be prepared to gracefully handle additional members of the response.
## Unauthenticated
This indicates that the request has not been applied because it lacks valid authentication
credentials for the target resource. Please check that you have valid credentials.
## PermissionDenied
This response means that the server understood the request but refuses to authorize
it because it lacks sufficient rights to the resource. It happens when you do not have the
necessary permission to execute the action you performed. You need to get the appropriate
permissions in other to resolve this error.
## BadRequest
This response means that the server cannot or will not process the request due to something
that is perceived to be a client error (e.g., malformed request syntax, invalid request message
framing, or deceptive request routing). To resolve this, please ensure that your syntax is correct.
## NotFound
This client error response indicates that the server cannot find the requested resource.
## MethodNotAllowed
Indicates that the request method is known by the server but is not supported by the target resource.
## NotAcceptable
The target resource does not have a current representation that would be acceptable to the user
agent, according to the proactive negotiation header fields received in the request, and the
server is unwilling to supply a default representation.
## AlreadyExists
The request could not be completed due to a conflict with the current state of the target
resource, e.g. the resource it tries to create already exists.
## Unknown
This means that the server encountered an unexpected condition that prevented it from
fulfilling the request.

## Documentation For Authorization
By default the generated client supports the three authentication schemes:
* Basic
* GoogleOpenID
* Kerberos
However, you can generate client and documentation with your own schemes by adding your own schemes in
the security section of the OpenAPI specification. You can do it with Breeze CLI by adding the
``--security-schemes`` option to the ``breeze release-management prepare-python-client`` command.
## Basic "smoke" tests
You can run basic smoke tests to check if the client is working properly - we have a simple test script
that uses the API to run the tests. To do that, you need to:
* install the `apache-airflow-client` package as described above
* install ``rich`` Python package
* download the [test_python_client.py](test_python_client.py) file
* make sure you have test airflow installation running. Do not experiment with your production deployment
* configure your airflow webserver to enable basic authentication
In the `[api]` section of your `airflow.cfg` set:
```ini
[api]
auth_backend = airflow.api.auth.backend.session,airflow.api.auth.backend.basic_auth
```
You can also set it by env variable:
`export AIRFLOW__API__AUTH_BACKENDS=airflow.api.auth.backend.session,airflow.api.auth.backend.basic_auth`
* configure your airflow webserver to load example dags
In the `[core]` section of your `airflow.cfg` set:
```ini
[core]
load_examples = True
```
You can also set it by env variable: `export AIRFLOW__CORE__LOAD_EXAMPLES=True`
* optionally expose configuration (NOTE! that this is dangerous setting). The script will happily run with
the default setting, but if you want to see the configuration, you need to expose it.
In the `[webserver]` section of your `airflow.cfg` set:
```ini
[webserver]
expose_config = True
```
You can also set it by env variable: `export AIRFLOW__WEBSERVER__EXPOSE_CONFIG=True`
* Configure your host/ip/user/password in the `test_python_client.py` file
```python
import airflow_client
# Configure HTTP basic authorization: Basic
configuration = airflow_client.client.Configuration(
host="http://localhost:8080/api/v1", username="admin", password="admin"
)
```
* Run scheduler (or dag file processor you have setup with standalone dag file processor) for few parsing
loops (you can pass --num-runs parameter to it or keep it running in the background). The script relies
on example DAGs being serialized to the DB and this only
happens when scheduler runs with ``core/load_examples`` set to True.
* Run webserver - reachable at the host/port for the test script you want to run. Make sure it had enough
time to initialize.
Run `python test_python_client.py` and you should see colored output showing attempts to connect and status.
## Notes for Large OpenAPI documents
If the OpenAPI document is large, imports in client.apis and client.models may fail with a
RecursionError indicating the maximum recursion limit has been exceeded. In that case, there are a couple of solutions:
Solution 1:
Use specific imports for apis and models like:
- `from airflow_client.client.api.default_api import DefaultApi`
- `from airflow_client.client.model.pet import Pet`
Solution 2:
Before importing the package, adjust the maximum recursion limit as shown below:
```python
import sys
sys.setrecursionlimit(1500)
import airflow_client.client
from airflow_client.client.apis import *
from airflow_client.client.models import *
```

An API is broken up by its\nendpoint's corresponding resource.\nThe name of a resource is typically plural and expressed in camelCase. Example: `dagRuns`.\n\nResource names are used as part of endpoint URLs, as well as in API parameters and responses.\n\n## CRUD Operations\n\nThe platform supports **Create**, **Read**, **Update**, and **Delete** operations on most resources.\nYou can review the standards for these operations and their standard parameters below.\n\nSome endpoints have special behavior as exceptions.\n\n### Create\n\nTo create a resource, you typically submit an HTTP `POST` request with the resource's required metadata\nin the request body.\nThe response returns a `201 Created` response code upon success with the resource's metadata, including\nits internal `id`, in the response body.\n\n### Read\n\nThe HTTP `GET` request can be used to read a resource or to list a number of resources.\n\nA resource's `id` can be submitted in the request parameters to read a specific resource.\nThe response usually returns a `200 OK` response code upon success, with the resource's metadata in\nthe response body.\n\nIf a `GET` request does not include a specific resource `id`, it is treated as a list request.\nThe response usually returns a `200 OK` response code upon success, with an object containing a list\nof resources' metadata in the response body.\n\nWhen reading resources, some common query parameters are usually available. e.g.:\n\n```\nv1/connections?limit=25&offset=25\n```\n\n|Query Parameter|Type|Description|\n|---------------|----|-----------|\n|limit|integer|Maximum number of objects to fetch. Usually 25 by default|\n|offset|integer|Offset after which to start returning objects. For use with limit query parameter.|\n\n### Update\n\nUpdating a resource requires the resource `id`, and is typically done using an HTTP `PATCH` request,\nwith the fields to modify in the request body.\nThe response usually returns a `200 OK` response code upon success, with information about the modified\nresource in the response body.\n\n### Delete\n\nDeleting a resource requires the resource `id` and is typically executing via an HTTP `DELETE` request.\nThe response usually returns a `204 No Content` response code upon success.\n\n## Conventions\n\n- Resource names are plural and expressed in camelCase.\n- Names are consistent between URL parameter name and field name.\n\n- Field names are in snake_case.\n\n```json\n{\n \\\"name\\\": \\\"string\\\",\n \\\"slots\\\": 0,\n \\\"occupied_slots\\\": 0,\n \\\"used_slots\\\": 0,\n \\\"queued_slots\\\": 0,\n \\\"open_slots\\\": 0\n}\n```\n\n### Update Mask\n\nUpdate mask is available as a query parameter in patch endpoints. It is used to notify the\nAPI which fields you want to update. Using `update_mask` makes it easier to update objects\nby helping the server know which fields to update in an object instead of updating all fields.\nThe update request ignores any fields that aren't specified in the field mask, leaving them with\ntheir current values.\n\nExample:\n\n```python\nimport requests\n\nresource = requests.get(\"/resource/my-id\").json()\nresource[\"my_field\"] = \"new-value\"\nrequests.patch(\"/resource/my-id?update_mask=my_field\", data=json.dumps(resource))\n```\n\n## Versioning and Endpoint Lifecycle\n\n- API versioning is not synchronized to specific releases of the Apache Airflow.\n- APIs are designed to be backward compatible.\n- Any changes to the API will first go through a deprecation phase.\n\n# Trying the API\n\nYou can use a third party client, such as [curl](https://curl.haxx.se/), [HTTPie](https://httpie.org/),\n[Postman](https://www.postman.com/) or [the Insomnia rest client](https://insomnia.rest/) to test\nthe Apache Airflow API.\n\nNote that you will need to pass credentials data.\n\nFor e.g., here is how to pause a DAG with [curl](https://curl.haxx.se/), when basic authorization is used:\n\n```bash\ncurl -X PATCH 'https://example.com/api/v1/dags/{dag_id}?update_mask=is_paused' \\\\\n-H 'Content-Type: application/json' \\\\\n--user \\\"username:password\\\" \\\\\n-d '{\n \\\"is_paused\\\": true\n}'\n```\n\nUsing a graphical tool such as [Postman](https://www.postman.com/) or [Insomnia](https://insomnia.rest/),\nit is possible to import the API specifications directly:\n\n1. Download the API specification by clicking the **Download** button at top of this document.\n2. Import the JSON specification in the graphical tool of your choice.\n\n - In *Postman*, you can click the **import** button at the top\n - With *Insomnia*, you can just drag-and-drop the file on the UI\n\nNote that with *Postman*, you can also generate code snippets by selecting a request and clicking on\nthe **Code** button.\n\n## Enabling CORS\n\n[Cross-origin resource sharing (CORS)](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS)\nis a browser security feature that restricts HTTP requests that are\ninitiated from scripts running in the browser.\n\nFor details on enabling/configuring CORS, see\n[Enabling CORS](https://airflow.apache.org/docs/apache-airflow/stable/security/api.html).\n\n# Authentication\n\nTo be able to meet the requirements of many organizations, Airflow supports many authentication methods,\nand it is even possible to add your own method.\n\nIf you want to check which auth backend is currently set, you can use\n`airflow config get-value api auth_backends` command as in the example below.\n\n```bash\n$ airflow config get-value api auth_backends\nairflow.api.auth.backend.basic_auth\n```\n\nThe default is to deny all requests.\n\nFor details on configuring the authentication, see\n[API Authorization](https://airflow.apache.org/docs/apache-airflow/stable/security/api.html).\n\n# Errors\n\nWe follow the error response format proposed in [RFC 7807](https://tools.ietf.org/html/rfc7807)\nalso known as Problem Details for HTTP APIs. As with our normal API responses,\nyour client must be prepared to gracefully handle additional members of the response.\n\n## Unauthenticated\n\nThis indicates that the request has not been applied because it lacks valid authentication\ncredentials for the target resource. Please check that you have valid credentials.\n\n## PermissionDenied\n\nThis response means that the server understood the request but refuses to authorize\nit because it lacks sufficient rights to the resource. It happens when you do not have the\nnecessary permission to execute the action you performed. You need to get the appropriate\npermissions in other to resolve this error.\n\n## BadRequest\n\nThis response means that the server cannot or will not process the request due to something\nthat is perceived to be a client error (e.g., malformed request syntax, invalid request message\nframing, or deceptive request routing). To resolve this, please ensure that your syntax is correct.\n\n## NotFound\n\nThis client error response indicates that the server cannot find the requested resource.\n\n## MethodNotAllowed\n\nIndicates that the request method is known by the server but is not supported by the target resource.\n\n## NotAcceptable\n\nThe target resource does not have a current representation that would be acceptable to the user\nagent, according to the proactive negotiation header fields received in the request, and the\nserver is unwilling to supply a default representation.\n\n## AlreadyExists\n\nThe request could not be completed due to a conflict with the current state of the target\nresource, e.g. the resource it tries to create already exists.\n\n## Unknown\n\nThis means that the server encountered an unexpected condition that prevented it from\nfulfilling the request.\n\nThis Python package is automatically generated by the [OpenAPI Generator](https://openapi-generator.tech) project:\n\n- API version: 2.9.0\n- Package version: 2.9.0\n- Build package: org.openapitools.codegen.languages.PythonClientCodegen\n\nFor more information, please visit [https://airflow.apache.org](https://airflow.apache.org)\n\n## Requirements.\n\nPython >=3.8\n\n## Installation & Usage\n\n### pip install\n\nYou can install the client using standard Python installation tools. It is hosted\nin PyPI with `apache-airflow-client` package id so the easiest way to get the latest\nversion is to run:\n\n```bash\npip install apache-airflow-client\n```\n\nIf the python package is hosted on a repository, you can install directly using:\n\n```bash\npip install git+https://github.com/apache/airflow-client-python.git\n```\n\n### Import check\n\nThen import the package:\n\n```python\nimport airflow_client.client\n```\n\n## Getting Started\n\nPlease follow the [installation procedure](#installation--usage) and then run the following:\n\n```python\nimport time\nimport airflow_client.client\nfrom pprint import pprint\nfrom airflow_client.client.api import config_api\nfrom airflow_client.client.model.config import Config\nfrom airflow_client.client.model.error import Error\n\n# Defining the host is optional and defaults to /api/v1\n# See configuration.py for a list of all supported configuration parameters.\nconfiguration = client.Configuration(host=\"/api/v1\")\n\n# The client must configure the authentication and authorization parameters\n# in accordance with the API server security policy.\n# Examples for each auth method are provided below, use the example that\n# satisfies your auth use case.\n\n# Configure HTTP basic authorization: Basic\nconfiguration = client.Configuration(username=\"YOUR_USERNAME\", password=\"YOUR_PASSWORD\")\n\n\n# Enter a context with an instance of the API client\nwith client.ApiClient(configuration) as api_client:\n # Create an instance of the API class\n api_instance = config_api.ConfigApi(api_client)\n\n try:\n # Get current configuration\n api_response = api_instance.get_config()\n pprint(api_response)\n except client.ApiException as e:\n print(\"Exception when

the generated client supports the three authentication schemes:\n\n* Basic\n* GoogleOpenID\n* Kerberos\n\nHowever, you can generate client and documentation with your own schemes by adding your own schemes in\nthe security section of the OpenAPI specification. You can do it with Breeze CLI by adding the\n``--security-schemes`` option to the ``breeze release-management prepare-python-client`` command.\n\n## Basic \"smoke\" tests\n\nYou can run basic smoke tests to check if the client is working properly - we have a simple test script\nthat uses the API to run the tests. To do that, you need to:\n\n* install the `apache-airflow-client` package as described above\n* install ``rich`` Python package\n* download the [test_python_client.py](test_python_client.py) file\n* make sure you have test airflow installation running. Do not experiment with your production deployment\n* configure your airflow webserver to enable basic authentication\n In the `[api]` section of your `airflow.cfg` set:\n\n```ini\n[api]\nauth_backend = airflow.api.auth.backend.session,airflow.api.auth.backend.basic_auth\n```\n\nYou can also set it by env variable:\n`export AIRFLOW__API__AUTH_BACKENDS=airflow.api.auth.backend.session,airflow.api.auth.backend.basic_auth`\n\n* configure your airflow webserver to load example dags\n In the `[core]` section of your `airflow.cfg` set:\n\n```ini\n[core]\nload_examples = True\n```\n\nYou can also set it by env variable: `export AIRFLOW__CORE__LOAD_EXAMPLES=True`\n\n* optionally expose configuration (NOTE! that this is dangerous setting). The script will happily run with\n the default setting, but if you want to see the configuration, you need to expose it.\n In the `[webserver]` section of your `airflow.cfg` set:\n\n```ini\n[webserver]\nexpose_config = True\n```\n\nYou can also set it by env variable: `export AIRFLOW__WEBSERVER__EXPOSE_CONFIG=True`\n\n* Configure your host/ip/user/password in the `test_python_client.py` file\n\n```python\nimport airflow_client\n\n# Configure HTTP basic authorization: Basic\nconfiguration = airflow_client.client.Configuration(\n host=\"http://localhost:8080/api/v1\", username=\"admin\", password=\"admin\"\n)\n```\n\n* Run scheduler (or dag file processor you have setup with standalone dag file processor) for few parsing\n loops (you can pass --num-runs parameter to it or keep it running in the background). The script relies\n on example DAGs being serialized to the DB and this only\n happens when scheduler runs with ``core/load_examples`` set to True.\n\n* Run webserver - reachable at the host/port for the test script you want to run. Make sure it had enough\n time to initialize.\n\nRun `python test_python_client.py` and you should see colored output showing attempts to connect and status.\n\n\n## Notes for Large OpenAPI documents\n\nIf the OpenAPI document is large, imports in client.apis and client.models may fail with a\nRecursionError indicating the maximum recursion limit has been exceeded. In that case, there are a couple of solutions:\n\nSolution 1:\nUse specific imports for apis and models like:\n\n- `from airflow_client.client.api.default_api import DefaultApi`\n- `from airflow_client.client.model.pet import Pet`\n\nSolution 2:\nBefore importing the package, adjust the maximum recursion limit as shown below:\n\n```python\nimport sys\n\nsys.setrecursionlimit(1500)\nimport airflow_client.client\nfrom airflow_client.client.apis import *\nfrom airflow_client.client.models import *\n```\n\n## Authors\n\ndev@airflow.apache.org\n",
