The DPO Pay sandbox environment allows you to test your integration without processing real transactions.
All payments created in the sandbox are simulated and no funds are transferred. Use the credentials and endpoints on this page to build and validate your integration before going live.
Sandbox API Endpoint
Use the following base URL for all API requests in the sandbox environment:
https://secure.3gdirectpay.com/API/v6/Test Merchant Accounts
DPO Pay provides multiple sandbox merchant accounts for testing. Each account is identified by a Company Token and associated Service Type IDs.
You must include both values when creating a payment request.
