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. 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?

  • API enabled in your Athennian environment
    • Contact your Athennian CSM if you don't see this available and they can support you with pricing and ensuring the feature is enabled within your Athennian instance
  • A developer to write code and submit API calls
  • An HTTP client like Postman or Insomnia
  • Administrator level of permissions to view the "Access section" in Athennian

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?

  • Login to Athennian and navigate to the Access section
  • Obtain your API Key in Athennian
    • Navigate to the Access Section > API Keys.
