Prerequisites
Complete the following tasks before you start the integration:- Create a Cashfree Merchant Account.
- Log in to the Merchant Dashboard and generate an App ID and Secret Key. Learn how to generate API keys.
- Use Cashfree React Native SDK version 2.4.0 or above. Get it from npm.
- Set your Android application’s
minSdkVersionto API level 19 or higher. - Set your iOS minimum deployment target to 13.0 or higher.
Step 1
Create a subscription
Step 2
Open the payment page
Step 3
Confirm the payment
Step 1: Create a subscription Server-side
Create a subscription from your backend server before you process any payment.This API requires your secret key. Create subscriptions through your server only — do not call this API directly from your mobile application.
subscription_id and a subscription_session_id. Pass both values to your React Native client to proceed with the payment.

subscription_id and subscription_session_id. Use these values to build the CFSubscriptionSession object in Step 2. The API returns the following response on success:Step 2: Open the payment page Client-side
After you create the subscription, open the payment page so the customer can provide payment details.1. Set up the SDK
The React Native SDK is hosted on npm. You can get the SDK 2.4.0. The React Native SDK supports Android SDK version 19 and above and iOS minimum deployment target of 13.0 and above. Install the SDK in your React Native project:Android configuration
Add the following entry inside the<application> tag in your Android manifest file. If you do not enable the cashfree_subscription_flow_enable flag, the SDK will not provide a payment callback.
Add this entry inside the
<application> tag, not inside the <activity> tag.iOS configuration
Update your iOS deployment target in your Podfile to 13.0 or higher:pod install to install the dependency:
info.plist file:
2. Select a payment method
The Subscription Element SDK supports the following payment methods:- Card
- UPI
- eNach (net banking)
In this flow, the customer enters their card details directly in your application UI. The SDK securely processes the card payment and initiates the subscription mandate.
3. Complete the payment
To complete the payment, follow these steps:- Create a
CFSubscriptionSessionobject. - Create the payment object for the selected payment method.
- Set up the subscription callback.
- Initiate the payment using
makeSubsPayment().
Create a session
TheCFSubscriptionSession object holds the session context for the payment. It accepts the subscription_session_id and subscription_id obtained from Step 1, and the Cashfree environment (CFEnvironment.SANDBOX or CFEnvironment.PRODUCTION).
The following example shows how to create the session object:
Create a payment object
The SDK provides a dedicated payment class for each supported payment method. Build only the object that corresponds to the payment method your customer has selected.- Card
- UPI
- eNach (net banking)
Use the following code to create a card payment object:
Set up the subscription callback
The SDK exposes a callback interface to receive callbacks when the subscription payment journey ends. The callback supports two methods:Initiate the payment
CallmakeSubsPayment() to open the payment screen when the customer taps the pay button. Pass the payment object for your selected payment method.
Sample code
The following example shows a complete card payment flow, including session creation, payment object setup, callback registration, and payment initiation.Card payment sample

This SDK is compatible with the Expo framework. For a sample implementation, see the Expo sample on GitHub.
Step 3: Confirm the payment Server-side
After the SDK delivers a callback viaonVerify, confirm the payment status from your backend before taking any action. The SDK callback signals only that the payment flow has ended. It does not guarantee a successful payment.
Use the Fetch Details of All Payments of a Subscription API to retrieve the current payment status.
API request for fetching subscription payments
API request for fetching subscription payments
The following request fetches all payments for a subscription:A successful response returns an array of payment objects. Check the
payment_status field to determine the outcome. The API returns the following response on success:Always verify the subscription status from your backend before delivering goods or services to the customer. Proceed only when
payment_status is SUCCESS.Error codes
If a required field or object is missing when you initiate payment, the SDK throws an error. The following table lists SDK-level validation errors and when they occur.Show error codes
