Getting Started

In order to use APIs you must first complete the Get Started with APIs Agreements. These agreements will provide you Sandbox test keys for trial and development.

Note: The Sandbox API endpoints may not be configured like your client Credit Union. Each Credit Union is configured differently.

Once you have these agreements in place, you will be able to develop against a generic credit union. In order to develop against actual credit union data and configurations, the credit union will need to order a Credit Union Data Release. This will establish a test environment with a snapshot of credit union data. Next order Development API keys for access.

You must have a unique key for each application or API consumer for each client. For example, if you are making a mobile application, you must have a unique API key for iOS and a unique key for Android versions of your app. In addition, you must have unique keys for each client you are serving.

Finally, Production API Keys are required before launching your product to the marketplace.
