Access to Fiserv Omnipay API

1. Sign up for the APP Key

If you want to try out the Fiserv OmniPay Maintenance API please contact the Fiserv OmniPay PMO team (omnipay-pmogroup@fiserv.com) to have the project raised. As part of the project work, the APP key will be setup. The project team will also provide you with the access to the sandbox environment (UAT) for your institution to enable you to test the API to update merchant information in real time on the platform.

2.Using the APP Key

When you use the Fiserv OmniPay APIs you will need to add the APP Key and generate the Message-Signature in the header of the API. You can find out more about that in the following pages.
