Zeta payment services includes Pay with Zeta (PWZ) functionality that allows merchants to accept digital payments from Zeta users. Using PWZ, merchants can provide a quick, hassle-free and secure means of payment to pay for the purchases, thus offering a seamless digital payment experience to Zeta users through Zeta payment gateway. 

The PWZ services are available as RESTful APIs to the merchant developers who use these to build payment capabilities into their web and mobile application. With secured integration, merchants can accept payment from Zeta users.


As a business owner, you can access PWZ RESTful APIs and related methods which in turn calls the methods exposed by Zeta payment gateway. Zeta verifies the endpoints that connect to Zeta payment gateway and establishes a secure connection to prevent unauthorized access.

This also enables seamless secure payment experience where the complexity of payment handling and user authentication are safely handled by the PWZ RESTful APIs, allowing the merchants to only focus on accepting online payment from Zeta users.

Use Case

Once you've integrated Zeta libraries and established a secured HTTPS connection, you can use the PWZ to generate regular, one-time E-com based payment requests from Zeta users.

Proof of Concept

This demonstration explains about the user flow once you've successfully integrated the PWZ functionality into your project.


A registered phone number linked to a valid Zeta user account.

If you don't have a valid account, create a Zeta account by following the instructions as mentioned in the User Account Setup page.
