How to add bKash payments to a Laravel website

bKash is the payment method most Bangladeshi customers reach for first, so it is usually the first gateway we wire into a new site.

Start in the sandbox. Apply for merchant credentials, put them in your .env, and build the checkout against the sandbox URLs. Keep the app key, app secret, username and password out of the codebase.

The flow has three steps: create the payment, send the customer to bKash, then execute the payment when they come back. The mistake we see most often is trusting the redirect alone. Always call the execute endpoint and store the transaction ID, the amount and the status before you mark anything as paid.

Finally, log every callback, even the failed ones. When a customer says they paid and your system says they did not, that log is what settles it in seconds.
