When using this integration, WhatsApp only facilitates the communication between merchants and buyers. Merchants are responsible for integrating with a PSP from which they can generate Payment Links, and confirm their payment.

Before You Start

Familiarize yourself with the Orders API. Orders are the entrypoint for collecting payments in WhatsApp.

You will need an existing integration with a PSP to generate Payment Links and do automatic reconciliation when a payment is made.

You must update the order status as soon as a payment is made.

Integration steps

The following sequence diagram shows the typical integration with Payment Links.

1. Send an order details message

Follow the full integration guide in the Orders API page.

If Payment Link payment is available on this order, you will need to provide a payment_link to the payment_settings attribute. You can optionally include an order object with itemized products, fees, and discounts, or send a simplified message with just the total amount and payment settings.

The following images show how the order details message with Payment Links appears in WhatsApp, in both full and simplified versions.

Simplified payload example

You can send a simplified order details message without the order object. This is useful when you don’t need to send itemized product details and only need to collect the total payment amount.

  "to": "<PHONE_NUMBER>",
  "type": "interactive",
  "interactive": {

    },
    "action": {
      "name": "review_and_pay",
      "parameters": {
        "reference_id": "unique-reference-id",
        "type": "digital-goods",
        "payment_type": "br",
        "payment_settings": [
          {
            "type": "payment_link",
            "payment_link": {
              "uri": "https://my-payment-link-url"
            }
          }
        ],
        "currency": "BRL",
        "total_amount": {
          "value": 50000,
