Prepare the business and product flow

Start by documenting who will pay, when payment happens, how an order is identified and what the customer should see while confirmation is pending. Confirm shortcode ownership and follow the current Daraja onboarding requirements.

Build secure endpoints and callbacks

Use a practical, testable integration plan:

  • Create separate sandbox and production configuration.
  • Protect credentials and rotate them through a controlled process.
  • Validate callbacks and use idempotency to prevent duplicate updates.
  • Connect every payment event to an order, customer or reference.

Test before production

Test success, cancellation, timeout, duplicate and delayed callback scenarios. Give operations teams a clear way to inspect pending transactions and reconcile exceptions after launch.

A reliable payment experience explains what is happening—even when confirmation is not immediate.
