Payzah Gateway on the Shopify App Store

Free to install. Published by Payzah.

​
Before You Start

  • A Payzah merchant account — register through the Payzah app
  • Your Payzah API key from your dashboard
  • Admin access to your Shopify store

​
Installation

1

Install the app

Open the Payzah Gateway listing on the Shopify App Store and select Install. Log in to your Shopify store when prompted and approve the requested permissions.The app requests access to payment gateways and payment sessions in order to process transactions, and to store owner details for account verification.
2

Enter your API key

Once installed, open the Payzah Gateway app from your Shopify admin and paste in your API key from the Payzah dashboard.
Use your test key while setting up and switch to your production key only when you are ready to accept real payments.
3

Activate the payment method

In your Shopify admin, go to Settings → Payments. Payzah Gateway will appear among your available payment providers. Activate it so it shows at checkout.
4

Place a test order

Run a test transaction using the sandbox test cards to confirm the full flow: checkout, redirect to the payment page, and return to your store with the order marked paid.
5

Go live

Swap your test key for your production key, then place one small real order to confirm everything works end to end. Work through the Go-Live Checklist before announcing it to customers.
Payzah has published a short video walkthrough of the Shopify plugin — see the demo on YouTube.

​
What Your Customers See

At checkout, customers select Payzah as their payment method and are taken to a secure Payzah-hosted payment page. There they choose KNET, Visa, or Mastercard, complete the payment, and are returned to your store with their order confirmed.

​
Refunds

The Payzah Gateway app supports full refund control. Issue refunds from your Shopify admin, and the corresponding transaction is updated on the Payzah side.
Refunds can also be issued from your Payzah dashboard, or programmatically through the Refund API if you have a custom workflow.
