Custom Checkout, Charge, and Poll

with Cellulant

Initiate a custom checkout, charge the customer, and poll until the payment is resolved.

  1. Exchange the client credentials for a bearer access token used to authorize the checkout and charge calls.
  2. Initiate a host-to-host custom checkout and capture the checkout_request_id used to drive the charge.
  3. Post the charge request against the initiated checkout to push the USSD/STK prompt or card charge to the customer.
  4. Query the request status by merchant_transaction_id. Repeat while the charge is in flight; end once a payment is reported.
