Setup

Before you start, refer to our quickstart guide to get connected to our APIs. To test the API calls, you can use cURL from the command line, or a service such as Postman in our sandbox.

We have full sandbox environments for you to explore. The sandbox is completely isolated from the production environment, so feel free to experiment. When you're ready to move to production, talk to your relationship manager, who will get you production credentials to access the live environment.

Webhooks are an important component of any integration with Cross River. While APIs let you request data on demand, webhooks push real-time updates directly to your system—eliminating the need for constant polling and reducing latency. In many cases, webhooks are more efficient and reliable than APIs alone, ensuring your application stays in sync with critical events like account changes, transaction updates, and processing outcomes.

Register to receive webhook events. When webhook events are triggered, the event objects are sent to the registered URLs.
