Express Checkout and Poll Status

with Cellulant

Create an Express Checkout session and poll until payment status is resolved.

  1. Exchange the client credentials for a bearer access token used to authorize the checkout calls.
  2. Create a hosted Express Checkout session and return the short and long URLs the customer uses to pay.
  3. Query the status of the checkout request by merchant_transaction_id. Repeat this step while the request remains in flight; branch to the end once a payment is reported.
