# 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. # 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.

# Introduction Welcome to the documentation for the Sakari Messaging REST API. Sakari provides an advanced platform to drive large scale customized SMS communication REST is a web-service protocol that lends itself to rapid development by using everyday HTTP and JSON technology. To find out more about our product offering, please visit [https://sakari.io](https://sakari.io). # Quickstart For your convenience we have created a quickstart guide to get you up and running in 5 minutes. [https://sakari.io/blog/sakari-api-quickstart](https://sakari.io/blog/sakari-api-quickstart) # PostMan Collection We've created a simple set of examples using [PostMan](https://www.getpostman.com/) Simply click below to import these. You will need to setup three environment variables in PostMan - AccountId, ClientId and ClientSecret. Check out our PostMan blog post for more information [](https://app.getpostman.com/run-collection/d616e273edc916a7a6eb) # Finding your client id, client secret and account id To authenticate against the API's you will need three key pieces of data - client id - client secret - account id To retrieve these, simply login into [https://hub.sakari.io](https://hub.sakari.io) and click on the "cog" in the top right corner. In the popup dialog at the bottom you should see your API credentials and account id. If these are not visible you will need to click on "Request Credentials" # Versioning With any breaking changes we will introduce a new version of the API. The latest version is v1. The API uses an open schema model, which means server may add extra properties to responses. Likewise, the server will ignore any extra query parameters and request body properties. When you write clients, you need to ignore additional properties in responses to ensure they do not break. # Testing There are numerous tools available for testing the API's. We will include examples using curl and the client SDKs that we have created. If you would like to see an SDK in a language not currently available, please let us know. # Throttling / Limits Our API's have been specifically designed to support bulk messaging in a single API call. We therefore impose limits on the frequency of calling the APIs to prevent abuse or runaway processes. If you feel you need a higher limit, please contact us. If you hit the limit you will get a 429 error code returned from our servers # Errors The API uses standard HTTP status codes to indicate the success or failure of the API call. The body of the response will be JSON in the following format: ``` { "success": false, "error": { "code": "CONT-001", "message": "Invalid mobile number" } } ``` # Pagination For performance, most GET calls return a subset of data. This data is paginated for easy access. Most APIs which return collections of data will return a pagination object as such: ``` { "pagination": { "offset": 0, "limit": 10 "totalCount": 21 } } ``` When making calls to the API, you can adjust the slice of data returned using query parameters such as: `` https://api.sakari.io/v1/accounts/123/contacts?offset=20&limit=25 `` This will return 25 contacts with an offset of 20.

Use our API for systems integration or to build your own use cases. Sample scenarios include but are not limited to:

• 2-way integration: Triggering of Signls and updates in the third party systems when alert state changes occur
• Retrieving alarms for logging purposes
• Calendar integrations: Creation and management of on-call duties
• Punch users in and out based on external calendars
• etc.

AUTHENTICATION
Using the API requires an API key, which you can generate in the SIGNL4 portal under 'Developers'.
This key must then be specified in a special header in every HTTP request.
This header is called X-S4-Api-Key.

The base URL of the API is https://connect.signl4.com/api/.
