Getting started

To start using the Adfin APIs, you need to get in touch to our team via support@adfin.com or your Adfin integration manager.

Our API reference contains detailed information about the various endpoints available for the Adfin APIs.

The reference for each endpoint includes:

• an explanation of what it does.
• the required and optional parameters and any formatting restrictions.
• any required headers.
• example responses for successful and failed requests.

Information about the general functionality of our APIs, and how to integrate them, can be found in the documentation part of this site.

We hope that this reference will be a useful resource as you integrate our API into your project. If you have any feedback or requests, please submit it via the form at the bottom of the page.
