Merchant integration

Connect your checkout to Online Payment Gateway Bangladesh

Merchants move from due diligence to a test project, then connect a hosted payment page or API from their backend, validate signed postbacks, and request production activation after testing.

Hosted payment page

Your backend creates the payment, receives a page URL and sends the customer to the enabled BDT method flow.

API connection

Authenticate server requests with the assigned API key and project ID, pass the merchant reference, and keep credentials outside browser code.

Signed postback testing

Validate notification signatures and handle successful, failed, pending, duplicate and refund states before production traffic.

Settlement visibility

Give finance and operations teams clearer payment status, settlement context, refund notes, and reconciliation support.

How merchant onboarding works

  • Share your business details, website, payment volume, and required checkout methods.
  • We review the setup path and confirm the best integration route for your product.
  • Your team receives payment request, callback, and status-check implementation details.
  • Use the test project to capture payment and postback evidence before production access is activated.
  • After launch, payment status and settlement handling are monitored with your team.
