Alation Integration APIs

To integrate Alation with Telmai, you'll use a set of REST API endpoints to manage the connection, automatically or manually create data mappings, and perform other configuration tasks. These API calls enable Telmai to interact with your Alation data catalog for seamless data governance.

Setup

These endpoints allow you to configure, retrieve, and remove the core Alation integration with Telmai. All requests require your backend_service_host and tenant identifier.

Add or Update Integration

Use this endpoint to establish the connection between Telmai and Alation or to update an existing one. You'll need your Alation URL, a user ID, and a refresh API token.

• PUT {backend_service_host}/{tenant}/configuration/integrations/alation

• Request Body:

  JSON

  {
    "url": "https://<your_host>.alationcloud.com/",
    "user_id": 81,
    "refresh_api_token": "xxxxxx..."
  }

• Response:

  JSON

    "url": "https://<your_host>.alationcloud.com/",
    "user_id": 81
  }

Mappings

These endpoints handle the creation and management of mappings, which link Telmai data assets to specific tables in your Alation data catalog.

Start Automatic Mappings

This endpoint initiates a background job to automatically create mappings for your assets. You can optionally choose to overwrite existing mappings.

• POST {backend_service_host}/{tenant}/configuration/mappings/alation/auto

• Request Parameters:

  • should_overwrite: true or false (default is false).

• Response:

  JSON

    "message": "Creating Alation mappings started",
    "job_id": "f583cea0-640d-4c50-9153-e187f92a982e"
  }

  The response provides a job_id that you can use to track the status of the mapping job.
