# ZainCash for a website or app: scope and payment acceptance tests

> Current ZainCash documentation describes OAuth2 authorisation, server-side transaction creation and redirecting to the provider's returned payment URL. The backend verifies the outcome through authenticated notification or inquiry; a browser success page alone is not evidence that funds were collected.

## Version and environment before code

Start with the [official ZainCash documentation](https://docs.zaincash.iq/) rather than copying an unidentified older example. The documentation separates test and production credentials. Obtain merchant activation from the provider and keep credentials out of the app and repository.

Include environment setup, transaction records and test instructions in the handover. A button labelled ZainCash is not a complete integration.

## Turn requirements into an acceptance test

Create a sample order with a known amount and test success, cancellation and network interruption. Review the order reference, amount and staff-visible fulfilment status in each case. Add a repeated result to confirm it cannot create duplicate orders.

Agree how pending payments are handled: whether the order remains reserved and when staff review is required. A slow result should not prompt a second payment without checking the first. These are design and testing recommendations, not client measurements.

## Scope, fees and responsibility

Development cost depends on the app, backend and reporting scope. Merchant approval, transaction fees and settlement terms come directly from ZainCash; this article promises neither activation nor a particular fee.

Review the [payment gateway comparison](https://www.al-arjan.com/en/blog/iraq-payment-gateways) and include acceptance in the [software contract checklist](https://www.al-arjan.com/en/blog/software-contract-checklist).
