Receive Payments via Payment Gateways on WhatsApp

Your business can enable customers to pay for their orders through our partner payment gateways without leaving WhatsApp. Businesses can send customers order_details messages, then get notified about payment status updates via webhook notifications.

Overview

Currently, customers browse business catalogs, add products to cart, and send orders with our set of commerce messaging solutions, which includes Single Product Message, Multi Product Message, and Product Detail Page. Now, with the Payments API, businesses can send customers a bill, so the customer can complete their order by paying the business without having to leave WhatsApp.

Our payments solution is currently enabled by BillDesk, Razorpay, PayU and Zaakpay, a third-party payments service provider. You must have a BillDesk, Razorpay, PayU or Zaakpay account in order to receive payments on WhatsApp.

We expect more payment providers to be added in the future.

How It Works

First, the business composes and sends an order_details message. An order_details 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.

Each order_details message contains a unique reference_id provided by the business, and that unique ID is used throughout the flow to track the order.

Once the message is sent, the business waits for a payment status update via webhooks. Businesses get notified when the payment status changes, but they must not solely rely on these webhooks notifications due to security reasons. WhatsApp also provides a payment lookup API that can be used to retrieve the payment statuses directly anytime.

Purchase Flow in App

In the WhatsApp Messenger App, the purchase flow has the following steps:


  1. Customers send an order with selected products to the business either through simple text messages or using other interactive messages such as Single Product Message, Multi Product Message, and Product Detail.
  2. Once the business receives the order, they send an order_details message to the user. When the user taps on Review and Pay, they will see details about the order and total amount to be paid.
  3. When the user taps the Continue button, they are able to choose to pay natively on WhatsApp or any other UPI app.

    Checkout on other UPI Apps

  4. Once the payment has been confirmed by your payment gateway (PG) or payment service provider, the business can start processing the order.
  5. Businesses can then send an order_status message to the consumer informing them about the status of the order. Each message will result in a message bubble (as shown below) that refers to the original order details message and also updates the status displayed on the order details page.

To receive payments on WhatsApp, you must add a payment configuration to the corresponding WhatsApp Business Account. A payment configuration allows you to link a payment gateway account to WhatsApp. Each payment configuration is associated with a unique name. As part of the order_details message, you can specify the payment configuration to use for a specific checkout. WhatsApp will then generate a checkout flow using the associated payment gateway account.

After linking your payment partner account, you must integrate with the Payments APIs below. This will allow you to send an order_details message to customers with the payment configuration to receive payments.

Note: Make sure no new order messages requesting payment from consumer are sent with the payment config your are trying to remove before you perform the unlink action.

Integration Steps

The steps outlined below assume that the business already knows what the user is interested in through earlier conversations. The Payments API is a standalone API and hence can work with various messages such as List Messages, Reply Buttons, Single or Multi-Product Messages.

The following sequence diagram demonstrates the typical integration flow for Payments API. The steps higlighted in green are the key integration steps.

          }
        }
      }
    }
  }
}

Step 3: Add Common Message Parameters

Once the interactive object is complete, append the other parameters that make a message: recipient_type, to, and type. Remember to set the type to interactive.

{
   "messaging_product": "whatsapp",
   "recipient_type": "individual",
   "to": "PHONE_NUMBER",
   "type": "interactive",
   "interactive": {
     // interactive object here     
   }
 }

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:

{
  "messaging_product": "whatsapp",
  "contacts": [ {
      "input": "[PHONE_NUMBER_ID]",
      "wa_id": "[PHONE-NUMBER_ID]"
  } ],
  "messages": [ {
      "id": "wamid.HBgLMTY1MDUwNzY1MjAVAgARGBI5QTNDQTVCM0Q0Q0Q2RTY3RTcA"
  } ]
}

For all errors that can be returned and guidance on how to handle them, see WhatsApp Cloud API, Error Codes.

An example successful response looks like this:

{
  "payments": [{
    "reference_id": "reference-id-value",
    "status": "status-of-payment",
    "currency": "INR",
    "total_amount": {
      "value": 21000,
      "offset": 100
    },
    "transactions": [
      {
        "id": "[PG-TXN-ID]",
        "type": "billdesk/razorpay/payu/zaakpay",
        "status": "success/failed",
        "created_timestamp": "CREATED_TIMESTAMP",
        "updated_timestamp": "UPDATED_TIMESATMP",
        "method": {
           "type": "upi/card/netbanking/wallet"
        },
        "error": {
           "code": "pg-generated-error-code",
           "reason": "pg-generated-descriptive-reason"
        },
        "refunds": [
          {
            "id": "[REFUND-ID]",
            "amount": {
              "value": 100,
              "offset": 100
            },
            "speed_processed": "instant/normal",
            "status": "success",
            "created_timestamp": "CREATED_TIMESTAMP",
            "updated_timestamp": "UPDATED_TIMESATMP",
          }
        ],
      }
    ],
    "receipt": "receipt-value",
    "notes": {
      "key1": "value1",
      "key2": "value2"
    },
    "udf1": "udf1-value",
    "udf2": "udf2-value",
    "udf3": "udf3-value",
    "udf4": "udf4-value"
    "additional_info1": "additional_info1-value",

In the case of any errors, response is similar to an error response for /v1/messages endpoint. For all errors that can be returned and guidance on how to handle them, see WhatsApp On-Premises API, Errors. Show here is an example for a generic error:

{
  "errors": [{
    "code": 500,
    "title": "Generic error",
    "details": "System error. Please try again."
  }]
}

Step 4: Update Order Status

Businesses must send updates to their order using the order_status message instead of text messages since the latest status of an order displayed on the order details page is only based on order_status messages.

To notify the customer with updates to an order, you can send an interactive message of type order_status as shown below.

{
  "recipient_type": "individual",
  "to": "whatsapp-id",
  "type": "interactive",
  "interactive": {
    "type": "order_status",
    "body": {
      "text": "your-text-body-content"
    },
    "action": {
      "name": "review_order",
      "parameters": {
        "reference_id": "reference-id-value",
        "order": {
          "status": "processing | partially_shipped | shipped | completed | canceled",
          "description": "optional-text"
        }
      }
    }
  }
}

The following table describes the fields in the order_status interactive message:

Product Experience

Customers receive each order_status update as a separate message in their chat thread, that references their original order_details message as shown below (left). The order details page always displays the latest valid status communicated to the customer using the order_status message as shown below (right).

Supported Order Status and Transitions

Currently we support the following order status values:

ValueDescription

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

Order status transitions are restricted for consistency of consumer experience. Allowed status transitions are summarized below:

  • Initial status of an order is always pending, which is sent in order_details message.
  • canceled and completed are terminal status and cannot be updated to any other status.
  • pending can transition to any of the other statuses including processing, shipped, partially-shipped.
  • processing, shipped and partially-shipped are equivalent statuses and can transition between one another or to one of the terminal statuses.

Upon sending an order_status message with an invalid transition, you will receive an error webhook with the error code 2046 and message "New order status was not correctly transitioned."

Canceling an Order

An order can be canceled by sending an order_status message with the status canceled. The customer cannot pay for an order that is canceled. The customer receives an order_status message and order details page is updated to show that the order is canceled and the "Continue" button removed. The optional text shown below "Order canceled" on the order details page can be specified using the description field in the order_status message.

An order can be canceled only if the user has not already paid for the order. If the user has paid and you send an order_status message with canceled status, you will receive an error webhook with error code 2047 and message "Could not change order status to 'canceled'".

Step 5: Reconcile Payments

WhatsApp does not support payment reconciliations. Businesses should use their payment gateway account to reconcile the payments using the reference_id provided in the order_details messages and the id of the transactions returned as part of the payment lookup query.

Step 6: Refunds

Business can initiate a refund for an order. To do that, businesses must make a POST call to the /[PHONE_NUMBER_ID]/payments_refund endpoint with the following JSON object:

{
  "reference_id": "reference-id-value",
  "speed": "normal",
  "payment_config_id": "payment-config-id",
  "amount": {
    "currency": "INR",
    "value": "100",
    "offset": "100"
  }
}

The following table describes the fields in the refunds endpoint request object:

FieldDescription

reference_id

string

Required.

Unique reference ID for the order sent in order_details message.

speed

string

Optional.

Speed by which refund should be processed. Can be one of instant or normal.


payment_config_id

string

Required.

Payment configuration for the order sent in order_details message.

amount

object

Required.

The amount object contains the following fields:

offset string

  • Required. Must be 100 for INR.

value string

  • Required. Positive integer representing the amount value multiplied by offset. For example, ₹12.34 has value 1234.

currency string

  • Required. The currency for this refund. Currently the only supported value is INR.

Businesses should expect a response in the same HTTP session (not in a webhook notification) that contains the following fields:

FieldDescription

id

string

Required.

A unique ID representing the initiated refund.

status

string

Required.

Status of the refund. Can be one of pending, failed or completed


speed_processed

string

Required.

Speed by which refund was processed. Can be one of instant or normal. PGs are the ultimate arbitrator of which speed mode refund goes through. This might NOT always match what was included in the request parameters.

An example successful response looks like this:

{
  "id": "refund-id",
  "status": "pending",
  "speed_processed": "normal"
}

Merchant Preferred UPI Payment Method

List of payment options

Enabled Option Experience in checkout flow

upi

Only UPI apps are showin in checkout flow

web

Payment gateway webpage is loaded and merchant payment gateway account configured payment options will be shown in the checkout flow.

Some Payment Gateways allow customization of payment options that are shown in payment link or web based checkout flow. Please contact Payment Gateway to restricting payment options in payment link or web page.

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 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 incase consumer wants to report any issues.

  • Migrate to "payment_settings" in place of "payment_type" and "payment_configuration". This is the recommended way, and gives access to features likes "notes" and "udf" fields. For an example, view the payloads above.
