payhere-js-sdk

Full Fledged JavaScript SDK for payhere.lk

Payhere, one of the most popular payment gateways in Sri Lanka, lacks a developer-friendly integration with modern front-end JS frameworks like React.js, Angular.js, and Vue.js etc. But worry not! We have developed an NPM package specifically designed to effortlessly integrate Payhere into your single-page web app, ensuring a seamless user experience.

Have a look at example code or the demo React.js app.

Features

• Works in front end JS frameworks
• Making one time payments with Checkout API
• Making Recurrent payments with Recurring API (monthly, daily. annually)
• Get payments data of your Payhere account using Retrieval API
• Linking customers payment info with your app for making future payments at any time without customer intervention
• subscriptions management (Find, retry and cancel subscriptions)

Installation

With NPM

npm install payhere-js-sdk

With Yarn

yarn add payhere-js-sdk

With pnpm

pnpm i payhere-js-sdk
