The Athennian API makes it easy to integrate your entity data into other applications or systems. Use this guide to get started sharing your data across systems.


Easy to access. Easy to modify.

The Athennian API is a GraphQL Internet protocol built around making semantically meaningful HTTPS requests to access or modify a resource (usually done by an employee). The API can be used to manipulate entity data and to generate reports in several formats.

GraphQL provides the flexibility to request exactly what is needed and nothing more. Construct a request by defining the resources you want via a POST request and receive a response that matches the format of your request.


What will you need to get started?

  • A software developer to write code
  • An HTTP client like Postman or Insomnia
  • API purchased within your Athennian subscription

What does the Athennian API support?

Here’s a high-level view of everything v1 handles:

  • Fetch all the entities within Athennian
  • Fetch only the specific fields within an entity that you want

With an Athennian API Key, you will be granted access to specific entity profiles based on the configuration of Access Groups in Athennian. 

How do I configure the API?

  • Obtain your API Key in Athennian
    • Navigate to the Access Section > API Keys. If this section does not appear, contact your Customer Success Manager to enable this feature within your subscription. 
    • Click + New in the top right corner and name your API key
