FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Informations about the package upi-gateway

upi-gateway

Provider-agnostic PHP library for UPI QR code generation and payment status polling. Switch payment gateways — and environments — with a single config change.

Latest Version PHP Version

Installation

Requires PHP 8.1+.

Supported Providers

Provider Sandbox URL Live URL QR Poll Refund Webhook
Razorpay api.razorpay.com (test keys) api.razorpay.com (live keys) ✅ ✅ ✅ ✅
PhonePe api-preprod.phonepe.com api.phonepe.com ✅ ✅ ✅ ✅
Paytm pguat.paytm.io securegw.paytm.in 🚧 🚧 🚧 🚧

Razorpay note: Razorpay uses the same base URL for both environments. Sandbox mode is activated by using test-mode API keys (rzp_test_*). Live mode uses production keys (rzp_live_*).

Configuration

Provide both sandbox and live credentials upfront. The active environment determines which set is used at runtime — no code changes needed when going live.

Shorthand (single key pair)

If you only have one set of credentials (e.g. during initial development), you can use the plain key_id / key_secret keys and the adapter will fall back to them:

Usage

1. Generate a UPI QR code

2. Poll for payment status

Synchronous:

Async / queue-based (recommended for production):

3. Handle webhooks

4. Switch provider or environment at runtime

Important: Never switch to live environment at runtime in a test or staging context. The environment should be set via config and treated as deployment-level configuration.

Adding a Custom Provider
