The core app used familiar patterns — Kotlin, Jetpack Compose, MVVM, and Room — but payment integration introduced new challenges: managing distinct payment states (pending, success, failed, cancelled), configuring Razorpay's sandbox environment, and designing UI that never assumes success before confirmation. The key takeaway is to model all payment outcome states explicitly before writing any UI, rather than bolting error handling onto a working happy path. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What are the key states I need to handle when integrating Razorpay payments in an Android app? Payment flows need explicit states for pending, success, failed, and cancelled outcomes, rather than treating the payment call like a normal API request. The gap between a user tapping pay and Razorpay confirming success, failure, or cancellation must be handled explicitly in the UI so the user is never left uncertain whether money actually moved. Designing these states before building the happy-path UI produces a more robust feature. _Developers wiring up Razorpay or similar gateways can find more real-world integration lessons on daily.dev._ ### Why is testing a payment gateway integration in sandbox mode harder than expected? Configuring a payment gateway's sandbox environment correctly, including test keys and test cards behaving like real payments, can take longer than building the actual UI around it. This was found true when setting up Razorpay's test mode for an Android finance app, where getting the sandbox quirks right consumed more time than expected relative to the interface work. _Anyone debugging sandbox payment setups can compare notes on similar integration hurdles via daily.dev._ ## Similar posts on daily.dev - [Lessons From Building a Global Platform for Seamless Payments](https://daily.dev/posts/lessons-from-building-a-global-platform-for-seamless-payments-qifbvzbhl) · The New Stack · 0 upvotes · 0 comments - [Building a Real Web3 Payment Flow with XRPL & Xaman Wallet \(Without Smart Contracts\)](https://daily.dev/posts/building-a-real-web3-payment-flow-with-xrpl-xaman-wallet-without-smart-contracts--chjvd3gye) · Coins Bench · 0 upvotes · 0 comments - [UPI Payment Flow on Android: From URI Construction to Result Verification](https://daily.dev/posts/upi-payment-flow-on-android-from-uri-construction-to-result-verification-ak7oqwx8n) · ProAndroidDev · 0 upvotes · 0 comments --- Tags: [#android](https://daily.dev/tags/android), [#kotlin](https://daily.dev/tags/kotlin), [#jetpack-compose](https://daily.dev/tags/jetpack-compose) [View this post on daily.dev](https://daily.dev/posts/building-walletx-what-i-learned-integrating-razorpay-into-a-personal-finance-app-rqipdyabr) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Building WalletX: What I Learned Integrating Razorpay Into a Personal Finance App","url":"https://daily.dev/posts/building-walletx-what-i-learned-integrating-razorpay-into-a-personal-finance-app-rqipdyabr","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/building-walletx-what-i-learned-integrating-razorpay-into-a-personal-finance-app-rqipdyabr"},"datePublished":"2026-08-02T08:45:27.916Z","dateModified":"2026-09-14T07:04:27.468Z","description":"A developer shares lessons learned building WalletX, a personal finance Android app focused on integrating Razorpay as a payment gateway.
