Test Your Payzah Integration with Sandbox Test Cards

Before processing real payments, you should thoroughly test your integration using Payzah’s sandbox environment. The sandbox mirrors production behavior exactly, allowing you to simulate successful transactions and error scenarios without moving real money. Use the test credentials and endpoints below to verify every part of your integration end-to-end.

All test credentials listed on this page are exclusively compatible with the test endpoints. Sending these card details to production endpoints will result in failed or rejected transactions. Refer to the endpoint table below to ensure you are pointing to the correct URLs.

Public Sandbox API Key

You do not need a merchant account to start testing. Use the shared sandbox key below to run requests against the test environment straight away.

Field	Value
Authorization header value	`NzYxMGVlNjFhZDJkZGJlODAzYmU2MjZmNzZhYmM5OTZkNDdkY2JiZA==`

This value is already Base64-encoded, so paste it into the Authorization header exactly as shown — no further encoding needed.

Try it now

curl --request POST \
  --url https://development.payzah.net/ws/paymentgateway/index \
  --header 'Content-Type: application/json' \
  --header 'Authorization: NzYxMGVlNjFhZDJkZGJlODAzYmU2MjZmNzZhYmM5OTZkNDdkY2JiZA==' \
  --data '{
    "trackid": "DEMO-001",
    "amount": "1.000",
    "currency": "414",
    "payment_type": "3",
    "success_url": "https://example.com/success",
    "error_url": "https://example.com/error"
  }'

This key belongs to a shared demo account, so transactions created by other developers will also appear against it. Treat any data you see as public, and never send real customer details through it.

This key works only on the test environment. It cannot authenticate against production. Register through the Payzah app to receive your own private key before going live.

Test vs. Production Endpoints

Payzah provides distinct URLs for each environment. Make sure your integration reads the base URL from a configuration variable so you can switch between environments without changing code.

Operation	Environment	URL
Payment Initialization	Test	`https://development.payzah.net/ws/paymentgateway/index`
Payment Initialization	Production	`https://payzah.net/production770/ws/paymentgateway/index`
Payment Status Check	Test	`https://development.payzah.net/ws/paymentgateway/get-payment-details`
Payment Status Check	Production	`https://payzah.net/production770/ws/paymentgateway/get-payment-details`

Before switching your integration to the production endpoints, complete a full round of User Acceptance Testing (UAT). Cover every integration point — successful payments, declined cards, cancelled transactions, and status-check polling — so you can go live with confidence and minimize support issues.
