# Payment Integration & Operations Software

A payment journey needs a reliable answer about what happened, even when the network fails. Connect approved payment providers with application records, explicit transaction states and operational follow-up for results that need investigation.

## Define payment and order state transitions

Define what an initiated, authorised, completed or failed payment means for your application. An order should not be marked paid simply because a customer returns from a provider page. Use the provider's supported verification path and agreed identifiers.

## Handle repeats and late responses

Callbacks can arrive more than once or after the user has left. Plan duplicate handling and clear status recovery. Timeouts require investigation of the existing attempt before another charge is requested, and uncertain outcomes need an operational review route.

## Support refunds and reconciliation

Define who can request refunds and how their outcome is recorded. Compare application records with provider reports using agreed periods and identifiers. Keep sensitive payment information out of ordinary logs and use the provider's approved collection methods for the selected integration.

## Project deliverables

## Service questions and answers

### How should an application confirm that a payment succeeded?

Use the provider's supported confirmation route and verify the relevant identifiers and state. A shopper reaching a return page is not sufficient evidence. Order and payment records should remain separate so a pending or rejected payment does not accidentally become a completed purchase.

### How can repeated notifications avoid duplicate actions?

Give each payment operation an agreed identifier and define which transitions are valid. Processing the same provider event again should not repeat fulfilment or create another refund. Test duplicates, late notifications and interrupted processing against the provider's documented behaviour before relying on the integration.

### What should happen when a refund is still pending?

Record the request separately from its confirmed outcome and identify who can investigate it. Staff need the provider reference and relevant history. Customer messages should describe the actual state, while reconciliation highlights refunds that remain unresolved rather than assuming a submitted request has completed.

### Does a payment integration automatically establish security compliance?

No. Requirements depend on how data and transactions are handled. The provider and qualified reviewers should define the applicable scope and evidence. Use approved collection methods and avoid sensitive payment data in ordinary logs, but do not treat those measures alone as certification.
