| Test / Sandbox (Optional) | Used for testing only. No real money is processed. |
How PayLexer selects credentials:
-
Debug/Test mode ON → Test credentials are used
-
Debug/Test mode OFF → Live credentials are used
Test and save

Understanding Payment Notifications
DPO supports payment notifications through notification URLs. When a payment is created, you can specify a notification URL where DPO sends payment status updates.
How Payment Notifications Work
Payment link is created
A payment link is created with your notification URL included.
Customer completes payment
The customer completes payment on DPO's hosted page.
DPO sends notification
DPO sends a notification to your URL before redirecting the customer.
Payment status is updated
Payment status is updated instantly and the order is updated in your platform.
PayLexer automatically handles notification URL configuration for each transaction - no manual setup required.

Validate the first live transaction after switching to Live
-
Monitor the gateway dashboard for failed payments

During testing: ensure Debug/Test mode is enabled, use only DPO Test credentials, and save Test credentials in PayLexer - not just Live credentials
