Define each payment step before connecting the API.
A payment connection should reflect the way your business takes money and fulfils a service. We map the requested payment, customer reference, provider response and final status so each system can identify the same transaction.
Payment initiation: Scope hosted checkout, payment requests or other supported vendor methods, using the fields and authentication required by the provider.
Consistent references: Agree customer, invoice, order and transaction identifiers so a payment can be matched back to the correct record.
Credentials and environments: Separate test and live connections, define access ownership and plan credential changes without placing secrets in the client interface.
