Test Payments

To ensure your integration functions properly, use specific values in the sandbox environment to mimic transactions without actual money transfers.

Test cards enable you to replicate various scenarios, such as:

• Successful card payments based on brand or region
• Errors caused by declined transactions, fraudulent activity, or incorrect information
• Handling refunds and disputes
• Simulating authentication via 3D Secure or PIN codes

Testing other payment methods follows a similar process, with unique values assigned to each method. However, due to rate limits, sandbox isn’t suitable for performance testing.

Card Payment

You can use the following card numbers to test your integration,

Open Banking

When undertaking payments in test mode, you will be presented with an authentication screen for a mock bank account. The details are as follows,
