The sandbox provides simulations and special test numbers that will trigger specific responses or resource statuses. You can use these unique sandbox features to test how your integration handles different workflows and webhook notifications. Requests made to the sandbox environment will never hit banking networks, meaning they can’t affect your account balances and will never incur costs. Make sure to use our sandbox URL endpoint to do your testing: 
Sandbox:       https://api.sandbox.treasuryprime.com
Production:    https://api.treasuryprime.com
When you’re ready to go live with your application, switch the URL endpoint and API keys to the production environment.

Testing in Sandbox

When testing in sandbox you can simulate typical workflows and edge case scenarios for the following products: You can do your API testing in command line or using our Postman Collection as described below. Additionally, you can review account and transaction activities directly from the Console.
Be sure to check for internal firewalls that could reject simulated inbound requests from Treasury Prime, such as card simulations. Treasury Prime can supply a list of IPs to whitelist if needed.

​
Funds Settlement in Sandbox

Not all types of payments will settle funds when testing the API in Sandbox. Endpoints including /ach, /wire, and /apply/deposit may flow through to a final status as though it settled funds in Production, but it is expected that account balances in Sandbox will remain unaltered. An exception to this rule are Book Transfers. Payments made using the /book endpoint will transfer funds in Sandbox.

​
Postman Collection

Test our API in Sandbox immediately, using Treasury Prime Postman Collection. Postman is a visual editing tool for building and testing API requests without configuring a full development environment. To get started, open the Treasury Prime API Collection in Postman. Then you set your Postman environment settings with your API_KEY_ID and API_SECRET_KEY before you can test the different endpoints available in the Treasury Prime Postman Collection.
