Receive UPI Payments Through WhatsApp(Recommended) | Developer Documentation Receive UPI Payments Through WhatsApp(Recommended) Updated: Mar 11, 2026 For businesses working with Billdesk or Zaakpay payment gateways, use the deeper integration with these PGs. Refer to Payment Gateway Integration Guide For businesses working with Razorpay, PayU, or Cashfree payment gateways, use a faster integration path. Refer to Enhanced Payment Links This is the recommended UPI Intent integration. Using the older payment configuration method? See previous docs and plan to migrate to dynamic VPA. Your business can enable customers to pay for their orders using all the UPI Apps installed on their devices via WhatsApp. Businesses can send customers invoice ( order_details) messages, then get notified about payment status updates via webhook notifications from Payment Gateway. Overview Currently, customers browse business catalogs, add products to cart, and send orders in with our set of commerce messaging solutions, which includes Single Product Message, Multi Product Message, and Product Detail Page. With the WhatsApp Payments API, businesses can send customers a bill so the customer can complete their order with all the UPI Apps. How It Works The business must send an order_details message for the consumer to initiate payment. This type of message is a new type of interactive message, which always contains the same 4 main components: header, body, footer, and action. Inside the action component, the business includes all the information needed for the customer to complete their payment. An order_details message contains the following fields that are worth noting: upi_intent_link - Fields that will be supplied by your payment gateway and denote where a payment will be sent. reference_id - This is used to track the lifecycle of the order. Payment statuses are published against this ID. This could be order-id or transaction-id used to create the upi-intent at payment gateway. Once the message is sent, the business waits for a payment or transaction status updates directly from Payment Gateway. Upon receiving payment signal for an order, Business should relay this payment signal to consumer through interactive order status ( order_status) message. Updating users about the payment signal is important as this message updates the order details message and order details view for the consumer reflecting the order confirmation from the merchant. This is shown with an example in subsequent sections. Purchase Flow in App In the WhatsApp customer app, the purchase flow has the following steps: Customer sends an order with selected products to the business, or the business identifies the products that the customer has shown interest to purchase. After receiving the order/identifying the product, if a merchant accepts payment methods other than UPI, such as credit cards and payment wallets, then the merchant will send a message to the user to get their preferred payment method for the order. When consumers want to pay using UPI payment method, then merchants should retrieve the UPI payment intent by calling Payment Gateway. Merchant needs to use UPI intent to construct order details messages and send it to the consumer. When the consumer taps the Pay now/continue button, they will be given the option to choose UPI payment Apps - WhatsApp or any other UPI payments apps. Consumers may choose any UPI option to pay for the order. Consumer pays for the order and the payment method is saved for the future and automatically selected for the next payment transaction. Also, one quick note is the order details screen order-status will continue to show “Order pending” until the merchant sends order status interactive message. Once the payment is complete, the business receives a notification from Payment Gateway and the merchant needs to send order status updates to the consumer client notifying consumers about the progress to the order, this will update the order details message CTAs and order details screen - order status description. Integration Steps The steps outlined below assume that the business is about to send order details message to the consumer client. The following sequence diagram demonstrates the typical integration flow for WA Payments API: Step 1: Get UPI Intent from Payment Gateway Once the consumer has expressed their interest to purchase an item using UPI payment method, merchant needs to call payment gateway to create a UPI intent, the following is the sample UPI intent link: upi://pay?pa=abc@psp&pn=ABC&tr=877376394&   am=10.00&cu=INR&mode=00&purpose=00&mc=5399&tn=877376394 Merchant/Partner could send the entire UPI intent as it is in the upi_intent_link type payload. These will be discussed in detail below. Step 2: Assemble the Interactive Object To send an order_details message, businesses must assemble an interactive object of type order_details with the following components: Object Description type object Required. Must be “order_details”. header object Optional. Header content displayed on top of a message. If a header is not provided, the API uses an image of the first available product as the header body object Required. An object with the body of the message. The object contains the following field: text stringRequired if body is present. The content of the message. Emojis and markdown are supported. Maximum length is 1024 characters footer object Optional. An object with the footer of the message. The object contains the following fields: text stringRequired if footer is present.

It is case sensitive and cannot be an empty string and can only contain English letters, numbers, underscores, dashes, or dots, and should not exceed 35 characters. The reference_id must be unique for each order_details message for a given business. If there is a need to send multiple order_details messages for the same order, it is recommended to include a sequence number in the reference_id (for example, “BM345A-12”) to ensure reference_id uniqueness. type object Required. The type of goods being paid for in this order. Current supported options are digital-goods and physical-goods beneficiaries array Required for shipped physical-goods.

Remember to set the type to interactive. These are parameters common to all message types. Step 4:Make a POST Call to Messages Endpoint Make a POST call to the /[PHONE_NUMBER_ID]/messages endpoint with the JSON object you have assembled. If your message is sent successfully, you get the following response: Errors WhatsApp Payments Terms of Service Acceptance Pending If you see the following error, accept the WhatsApp Payments terms of service using the link provided in the error message before trying again. For all other errors that can be returned and guidance on how to handle them, see WhatsApp Cloud API, Error Codes. Step 5: Consumer Pays for the Order Consumers can pay using WhatsApp payment method or using any UPI supported app that is installed on the device. Step 6: Get Notified About Transaction Status Updates from payment gateway Businesses receive updates to the invoice via payment gateway webhooks, when the status of the user-initiated transaction changes. The unique identifier reference-id passed in order_details message can be used to map the transaction to the consumer invoice or interactive order details message. Please refer to our PG integration guide for the exact payment signals. Cashfree and CCAvenue Step 7: Update order status Upon receiving transaction signals from payment gateway through webhook, the business must update the order status to keep the user up to date. Currently we support the following order status values: Value Description pending User has not successfully paid yet processing User payment authorized, merchant/partner is fulfilling the order, performing service, etc. partially-shipped A portion of the products in the order have been shipped by the merchant shipped All the products in the order have been shipped by the merchant completed The order is completed and no further action is expected from the user or the partner/merchant canceled The partner/merchant would like to cancel the order_details message for the order/invoice. The status update will fail if there is already a successful or pending payment for this order_details message Typically businesses update the order_status using either the WhatsApp payment status change notifications or their own internal processes. To update order_status, the partner sends a order_status message to the user. The following table describes the returned values: Value Description reference_id The ID provided by the partner in the order_details message status The new order status description Optional text for sharing status related information in order_details. Could be useful while sending cancellation. Max character limit is 120 characters Merchant should always post this order-status message to the consumer after receiving transaction updates for an order. As the order_details message and order details screen experience is tied to to the order status updates. Security Considerations Businesses should comply with local security and regulatory requirements in India. They should not rely solely on the status of the transaction provided in the webhook and must use payment lookup API to retrieve the statuses directly from WhatsApp. Businesses must always sanitize/validate the data in the API responses or webhooks to protect against SSRF attacks. Checklist for Integrated Merchants Ensure that an order_status message is send to consumer informing them about updates to an order after receiving transaction updates for an order. Ensure the merchant is verified and WABA contact is marked with a verified check. Verify the WABA is mapped to appropriate merchant initiated messaging tier(1k, 10k and 100k per day) Merchant should list the customer support information in the profile screen in case the consumer wants to report any issues.
