Send Whatsapp Payment Message API (India)

Pre-Read Note

This WhatsApp Payment API feature is only available for WhatsApp businesses operating in India, catering specifically to their Indian customer base. Please note that access to this functionality is limited to transactions within the Indian region from Meta.

You can now send the Payment Message (order_details) and your business can enable customers to pay for their orders using all the UPI Apps installed on their devices or via Credit cards or Internet Banking via WhatsApp.

A WhatsApp Payment flow is a user-initiated conversation that is initiated by the user or available in the existing chatbot flow and sent as a free-form message.

Businesses can send customers invoice (order_details) messages, and then get notified about payment status updates via webhook notifications from Payment Gateway or Exotel (via Meta) based on the Payment method you choose to integrate.

Based on particular use cases, businesses can collect payment from customers using one of the following integrations.

UPI Intent
Payment Gateway

In case you want to support all the types of payment methods to your end users, then we would suggest you proceed ahead with the Payment Gateway method with preferred PGs (RazorPay or PayU) as natively supported by Meta. Other PGs would require a deep integration based on the requirement.

The below comparison will help you understand the differences and proceed accordingly.

User Experience:

User Experience	UPI Intent Mode	Payment Gateway Deep Integration Mode
Native support for "Other payment methods" Eg: Netbanking, cards, wallets	❌ Alternative: Send payment links	✅
Native support for UPI Intent	✅	✅
Native Payment Status Notification	❌	✅

Integration Features:

Integration Features	UPI Intent Mode	Payment Gateway Deep Integration Mode
Refunds from WhatsApp APIs	❌	✅
Payment Status from WhatsApp webhooks	❌	✅

Pre-requisites for integration

WhatsApp Payments APIs (explained below)
Access to merchant order trigger APIs / CSVs needed to trigger an order. (eg: amount, goods/service details). These are mandatory details required to construct and send the payment message, this can be integrated with our Chatbot console to automate the process.
Access to payment posting APIs needed to close an order (eg: ticket generation APIs to create tickets once payment is received). The Payment Gateway or Exotel will send the payment updates via the Callbacks, which needs to be used to update the payment flow.
In the case of Full Payment Gateway Deep Integration Mode
Payment Gateway Account (PG): This is to authorize the linking of their account to Whatsapp Business Manager.
In the case of UPI Intent Mode: Find out VPA IDs, & MCC for business from the merchant’s PG. Access to PG API docs:
- UPI Intent S2S calls
- Webhook configuration for payment status

Note: In the case of UPI Intent payment flow, the payment success & failure need to be integrated with the VPA's payment switch or the Payment Gateway to whomever the VPA IDs belong to. Exotel (via Meta) will not be able to send any callbacks natively and will require an integration to be done.

Before you start sending the Message with the order details and payment button, you need to complete the setup and follow the steps:

Get access to the WhatsApp Business Account (WABA) and the Payment Gateway Account.
Choose and Link the Payment Gateway Account to your WhatsApp Business Account. Steps explained here - WhatsApp Payments Integration Guide
Configure the user journey to purchase the product and initiate the Order Checkout message with or without the
Catalog message. (You can use our WhatsApp Catalog APIs)
Construct the order details message using the API explained below and send the message.

How it Works:

Initiating Payment: To kick off the payment process, the business sends an 'order_details' message to the consumer.
Unique Reference ID: Each 'order_details' message carries a unique reference_id provided by the business.
Tracking Order Status: After sending the 'order_details' message, the business patiently awaits payment or transaction status updates directly from the Payment Gateway.
Importance of Payment Signal Update (optional): Updating the user about the payment signal is vital and you can send the payment confirmation message to the users.

Status Callbacks

Status callback URL can be passed in the status_callback parameter in send message APIs and it can also be configured as default to receive the responses. The Exotel team will help you configure the default URL while onboarding.

If you pass the status callback URL in send message/template message APIs, status callbacks will be triggered to the respective URL
If you do not pass any status callback URL in send message/template message APIs, status callbacks will be triggered to the default URL, if any.

*NOTE: Any callback can be received only in one status callback URL at any time.

The sent message with the Order Details message will have a different Status Callback when the user completes the payment.

Update Order Status

You can now send the Payment Order Status message to the end-users after the payment success or failure to update the status of the order purchase using our Exotel APIs.

POST

https://<your_api_key>:<your_api_token><subdomain>/v2/accounts/<your_sid>/messages

Upon receiving transaction signals from the 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 an order_status message to the user.

Send Whatsapp Messages with Flows API

Pre-Read Note

Please understand that this feature is currently in Beta and it’s important to note that certain capabilities, such as Reports and Analytics are not yet available on the dashboard. We will be working on this and is part of our next phase launch.

You can now send a Message with a Flow in a user-initiated conversation as a free-form message with a Call To Action (CTA) using the Exotel APIs.

Before you start sending the Message with a Flow button, you need to create and publish the Flow JSON. Follow the below steps:

Log in to the Meta dashboard and select your WhatsApp Business Manager account where you intend to create the Flow JSON.
In the left-side menu, go to the Flows section under Account Tools.
Click on the Create Flow button or Start Building Flows. Follow the steps mentioned here to create your JSON Flow under Option 2: Using Flows Builder under the Account Tools section in the Create Flow section - WhatsApp Flows Integration Guide.

Note: Currently, the creation of templates with flows via API or on the Exotel dashboard is not supported. We plan to enable this feature soon. Until then, create the JSON Flows using the WhatsApp Manager on the Meta dashboard.

To send messages to a single number with configured Flow button content via Exotel API, make an HTTP POST request to:

POST

https://<your_api_key>:<your_api_token><subdomain>/v2/accounts/<your_sid>/messages

Replace <your_api_key> and <your_api_token> with the API key and token created by you.
Replace <your_sid> with your “Account sid".
Replace <subdomain> with the region of your account
1. <subdomain> of Singapore cluster is @api.exotel.com
2. <subdomain> of Mumbai cluster is @api.in.exotel.com

<your_api_key> , <your_api_token> and <your_sid> are available in the API settings page of your Exotel Dashboard

Status callback URL can be passed in the status_callback parameter in send message APIs and it can also be configured as default to receive the responses. The Exotel team will help you configure the default URL while onboarding.

If you pass the status callback URL in send message/template message APIs, status callbacks will be triggered to the respective URL
If you do not pass any status callback URL in send message/template message APIs, status callbacks will be triggered to the default URL, if any.

*NOTE: Any callback can be received only in one status callback URL at any time.

What is different for Flow Template?

The sent message with the Flow button will have the same delivery callbacks as another type of message.
But the incoming message callback is different than the other types of WhatsApp messages, please check the Receive Whatsapp Messages section to find the callback sample for the Flow messages.

Send Authentication Template Message

What is an Authentication Templates?

It allows businesses to send OTP or Delivery code messages to authenticate users through one-time passcodes, typically digit alphanumeric codes without users initiating the conversation over WhatsApp. This is launched as a Template message under the category of Authentication.

Please make sure your Authentication Template is created on the correct WABA ID before sending the template message.

Components

Fixed preset text: <VERIFICATION_CODE> is your verification code. Please note that you cannot edit or customize the Authentication message.
An optional security disclaimer: This is a preset text that gets added to your template message to display the security of your security, do not share this code.
Optional expiration warning: This is an optional present text that gets added to your message template as a footer to display the Code expiry time. This code expires in <NUM_MINUTES> minutes.
Buttons: The supported buttons are:
- Copy Code: Enables users to copy the code to the clipboard for manual entry.
- One-Tap Autofill: Allows users to autofill the code with a single tap.
- Zero-Tap (not a button): Seamlessly integrates code delivery within the app, currently supported on Android.

This document explains how to send approved authentication templates with one-time password buttons.

Body Properties

Placeholder	Description	Sample Value
ToNumber	The customer's WhatsApp phone number.	12015553931
one-time-password code	The one-time password or verification code is to be delivered to the customer. Note that this value must appear twice in the payload, one in the button. Maximum 15 characters.	12345 or FpnYnP

Currently, the creation of Templates with Flow via API or the Template Management Exotel dashboard is not supported. We plan to enable this feature in the future. Until then, you need to create Templates with Flow button using the Meta dashboard on the WhatsApp Manager. (Other types of template creation are supported via API and Exotel Dashboard.)

You can now send the Template message with the Flow button using the Exotel APIs. To start sending the Template message with the Flow button, you need to follow the below steps:

Log in to the Meta dashboard and select your WhatsApp Business Manager account where you intend to create the template.
In the left-side menu, go to the Templates section under Account Tools.
Click on the Create Template button. Choose the Marketing category and select Form as the sub-category.
Click on the Create button under the Buttons section. This action opens the Meta Flow Form Builder UI. Design the required form and submit the template for approval.

To send messages to a single number with configured Template message content via Exotel API, make an HTTP POST request to:

POST

https://<your_api_key>:<your_api_token><subdomain>/v2/accounts/<your_sid>/messages

Replace <your_api_key> and <your_api_token> with the API key and token created by you.
Replace <your_sid> with your “Account sid".
Replace <subdomain> with the region of your account
1. <subdomain> of Singapore cluster is @api.exotel.com
2. <subdomain> of Mumbai cluster is @api.in.exotel.com

<your_api_key> , <your_api_token> and <your_sid> are available on the API settings page of your Exotel Dashboard

The following are the POST parameters -

Parameter Name	Parameter Type	Mandatory/ Optional	Value
custom_data	String	Optional	This parameter can be used to send any custom data at the API request level. This will be passed back in the callback.
status_callback	String (URL)	Optional	Once the message reaches the terminal state, Exotel will do a POST callback to your endpoint if the URL is set as a parameter in the API.
whatsapp	Channel Object	Optional	Information related to the messages to be sent out on WhatsApp.

*The Whatsapp parameter mentioned here will be used to send messages through the Whatsapp communication channel. In the future, the API will be extended further to support other communication channels like SMS. Later, the SMS parameter can also be passed to send SMSes.

custom_data	String	Optional	This parameter can be used to send any custom data at the API request level. This will be passed back in the callback.

from	String	Mandatory	From number from which the message has to be sent

Status Callbacks

Status callback URL can be passed in the status_callback parameter in send message/template message APIs and it can also be configured as default to receive the responses. The Exotel team will help you configure the default URL while onboarding.

If you pass the status callback URL in send message/template message APIs, status callbacks will be triggered to the respective URL
If you do not pass any status callback URL in send message/template message APIs, status callbacks will be triggered to the default URL, if any.

*NOTE: Any callback can be received only in one status callback URL at any time

What is different for Flow Template?

The sent Template message with the Flow button will have the same delivery callbacks as another type of Template message.
But the incoming message callback is different than the other types of WhatsApp messages after the end-user fills and submits the Form on WhatsApp, please check the Receive Whatsapp Messages section to find the callback sample for the Flow messages.

Receive Whatsapp Flow Messages

Pre-Read Note

Please understand that this feature is currently in Beta and it’s important to note that certain capabilities, such as Reports and Analytics are not yet available on the dashboard. We will be working on this and is part of our next phase launch.

This is a new type of incoming message for the WhatsApp Flows Message.Upon flow completion, a response message will be sent to the WhatsApp chat. You will receive it in the same way as you receive all other messages from the user - via message webhook. This response field will contain flow-specific data provided by the end-users after submitting the filled flow form.

Receive messages webhook can be passed in the status_callback parameter in send message/template message APIs to receive replies on messages from the business. To receive any message from an end user that is not a reply to a business message, a default callback value needs to be configured. The Exotel team will help you configure the default URL while onboarding.

If you pass receive messages webhook in send message/template message APIs, reply messages from users will be triggered to the respective URL
If you do not pass any receive messages webhook in send message/template message APIs, reply messages from users will be triggered to the default URL, if any.
All user-initiated conversations and messages that are not a reply to business messages will be triggered to the default URL

*NOTE: Any messages from a user can be received only in one webhook at any time
