Getting started with the UPIPayments REST API
Keys, base URL, your first order and reading the reply. Everything a developer needs for the first hour.
Verifying UPIPayments webhooks in PHP, Node.js and Python
Never trust a webhook you have not verified. Copy-paste signature checks for the three most common stacks.
Idempotency: why you should always send an order_id
Networks fail, retries happen. A stable order_id makes order creation safe to repeat.
Handling payment statuses correctly in your shop
created, pending, success, failed, expired, refunded: what each status means and what your code should do.
Testing your integration in staging mode
Build with confidence: staging keys, the built-in simulator, and how to rehearse failures before customers see them.
Using the PHP SDK in five minutes
One file, no dependencies. Create orders, check status and verify webhooks with the UpiPaymentsClient class.
Integrating UPI into a Laravel application
A clean pattern for Laravel: a service class, a webhook route without CSRF, and a queued fulfilment job.
Showing your own QR code with Direct UPI
Need the QR inside your app or kiosk? Use upi_intent and qr_url from the order reply.
Understanding API error codes
From insufficient_wallet to daily_count_limit: what each error means and how to recover.
