Paytm All-in-One SDK

Paytm All-in-One SDK provides a swift, secure, and seamless payment experience to your users by invoking the Paytm app (if installed on your user’s smartphone) to complete payment for your order.


It enables you to accept payment via Paytm Wallet, Paytm Postpaid, Paytm Payments Bank, Saved Debit/Credit Cards, Net Banking, BHIM UPI, or EMI as available in your customer’s Paytm account. If the Paytm app is not installed on a customer's device, the transaction will be processed via web view within the All-in-One SDK.


Major highlights of All-In-SDK are mentioned below:

  • No OTP based account linking is required if a user is already logged onto the Paytm app

  • No redirection to the web page for payment in case Paytm app is installed on a user device

  • User gets access to its Paytm saved payment sources

  • Reduced transaction time for saved instruments due to no login requirement

  • Increased overall success rate

  • Easy integration of SDK with very less size

  • Support for subscription payments and bank offers

  • SDK support for both Native and Hybrid apps

  • Supports UPI onboarding if a user wants to link its UPI account for payment

  • Complete flexibility with merchants to present single or multiple payments sources to the user on Paytm app

Demo of payment through Paytm All-in-One SDK

Overview of payment through Paytm All-in-One SDK

  1. User visits your mobile application and adds goods/services into the shopping/order cart.

  2. Your backend server calls Initiate Transaction API to get the transaction token.

  3. Launch Paytm All-in-One SDK with the transaction token received in step 2.

  4. In case the Paytm app is installed on user's device, they complete the payment on Paytm app using their login credentials else the transaction will be processed via web view within the All-in-One SDK(Paytm hosted redirection flow).

  5. Paytm backend server processes the transaction and returns the transaction response to your app.

  6. Your backend server calls the Transaction Status API to verify the transaction response.

  7. After the successful validation of the transaction, order status is shown to the user on the app.

Integration methods for All-in-One solution

All-in-One SDK integration is supported for apps built on both native and hybrid frameworks. For the apps built on native frameworks, the solution can be integrated either using the SDK or Non-SDK based integration. For apps built on a hybrid framework, the relevant bridges are available to integrate the All-in-One SDK solution.

  • SDK based integration: You will integrate a lightweight SDK in your app that would check and invoke the Paytm app. In case the Paytm app is not installed, the transaction will be processed via a web view. Please refer to the integration steps here.
  • Non-SDK based integration: In case you do not want to integrate the SDK into your app, you can invoke the Paytm app through a deeplink provided in the response of the API. Please refer to the integration steps here.
  • Integration for Hybrid apps: If your app is built on a hybrid platform, Paytm provides a bridge for your platform to easily integrate the All-in-One SDK into your app. Paytm provides bridges for the following hybrid frameworks. Please click on the link below for detailed integration steps.
