Testing

Integration Testing Stage

To fully verify the integration, it is necessary to perform a test payment and go through the entire transaction lifecycle — from creation to receiving the final status.

1. Creating a Test Payment

• Generate a payment link using the Initiate Payment method, following the documentation.

• The test amount should be between 1 and 5 EUR.

1. Selecting a Test Bank and Scenario

The list of banks includes special test options. Each option simulates a specific final transaction status.

When choosing a bank, the expected result returned by the system after completing the payment is indicated in advance:

• All extra fields

• Canceled

• Not full Completed - ACCEPTED_SETTLEMENT_IN_PROCESS

• Pending - IN_PROGRESS

• Some extra fields

This allows you to deliberately test the handling of each possible payment status within your system.

Example

1. Status Handling and Business Logic Verification

   After completing the payment scenario, ensure that:

   • The order status in your system is updated correctly;

1. Receiving and Confirming Webhook Notifications

   As the payment status changes, you will receive webhook notifications. You must:

   • Accept the request on your server;

   • Validate it;

   • Return an HTTP status 200;

   • Include the string OK in the response body.

Receiving and Processing Webhooks

Thus, the testing stage should confirm the correctness of:

• Payment creation,

• Handling of all possible statuses,

• Receipt and confirmation of webhook notifications,
