# airflow-python-sdk
# 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 **C**reate, **R**ead, **U**pdate, and **D**elete 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:
```
resource = request.get('/resource/my-id').json()
resource['my_field'] = 'new-value'
request.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.
# Summary of Changes
| Airflow version | Description |
|-|-|
| v2.0 | Initial release |
# 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 POST '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.
# 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_backend` command as in the example below.
```bash
$ airflow config get-value api auth_backend
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, meaning that the resource already exists
## Unknown
This means that the server encountered an unexpected condition that prevented it from
fulfilling the request.

## Notes for Large OpenAPI documents
If the OpenAPI document is large, imports in airflow_python_sdk.apis and airflow_python_sdk.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_python_sdk.api.default_api import DefaultApi`
- `from airflow_python_sdk.model.pet import Pet`
Solution 1:
Before importing the package, adjust the maximum recursion limit as shown below:
```
import sys
sys.setrecursionlimit(1500)
import airflow_python_sdk
from airflow_python_sdk.apis import *
from airflow_python_sdk.models import *
```
