Postman Quick Start

Setting up Postman to call the Keap API


If you do not yet have a Personal Access Token or Service Account Key configured in your Keap application you will need to do so before proceeding.

See our guide to PATs and SAKs for details.


  • You can sign up for a free Postman account at

  • Once signed in you will have a blank workspace available. Clicking on the “+” in the central row of tabs will open a new Request window.

  • In the new Request window provide the following parameters:

    Header Name: X-Keap-API-Key
    Header Value: Your PAT/SAK

    You can then make the API call by pressing the “Send” button, and you should receive a response from the server that lists the first page of Contact records in the application.
