Getting Started

Steps to API success

1. Register in our Developer Portal

2. Verify your email, follow the on-screen Multi-Factor Authentication (MFA) steps and log in, and log in.

3. Go to the API Keys page — you will find a pre‑generated Test Sandbox Key with access to all APIs and a dummy Store ID, so you can begin testing straight away!

   

   

How do I get a Production API key?

Once you have completed your testing in the Sandbox environment, you can also request a Production API key through our Developer Portal - follow the steps below to get started:

1. Go to the API Keys page and click “Create new key”.

2. Select “Production” as the environment and fill out the form details relevant to your API Key request.

3. 

   Once you request a production key, our team will review and validate your submission before activating it.

   You may receive an email asking for additional details — please check your inbox. If prompted, you will need to complete a support form before your application can proceed.

   

How do I use my API Key?

Our APIs use API keys to authenticate your requests and ensure your data stays protected and secure.

To use the API key on a request, you must include it in the API-Key request header.

curl -H "API-Key: <your key>" https://prod.emea.api.fiservapps.com/sandbox/exp/v1/authorisations
