platform to WhatsApp. Businesses can send customers invoice(<code>order_details</code>) messages, then get notified about payment status updates via webhook notifications from Payment Gateway.</p> <div class="_57yz _57z1 _3-8p"><div class="_57y-"><p>This feature is not publicly available yet. Please reach out to the Meta Business Engineering teams to know more.</p> </div></div></div></div><div class="_4-u2 _57mb _1u44 _3fw6 _4-u8"><div class="_4-u3 _588p"><h2>Overview</h2> <p>Currently, customers browse business catalogs, add products to cart, and send orders in with our set of commerce messaging solutions, which includes <a href="https://developers.facebook.com/docs/whatsapp/guides/commerce-guides/share-products-with-customers">Single Product Message, Multi Product Message, and Product Detail Page</a>.</p> <p>With the WhatsApp Messaging API, businesses can send customers a bill to complete the order with one of the supported payment instrument.</p> </div></div><div class="_4-u2 _57mb _1u44 _3fw6 _4-u8"><div class="_4-u3 _588p"><h2>How It Works</h2> <p>The business must send an <code>order_details</code> 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: <strong>header</strong>, <strong>body</strong>, <strong>footer</strong>, and <strong>action</strong>. Inside the <strong>action</strong> component, the business includes all the information needed for the customer to complete their payment.</p> <p>Each <code>order_details</code> message contains a unique <code>reference_id</code> provided by the business, and that unique number is used throughout the flow to track the order. This <code>reference_id</code> is used to generate the payment link from Payment Gateway.</p> <p>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 client through interactive order status(<code>order_status</code>) message.</p> <p>Updating user 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 merchant. This is shown with an example in subsequent sections.</p> </div></div><div class="_4-u2 _57mb _1u44 _3fw6 _4-u8"><div class="_4-u3 _588p"><h2>Purchase Flow in App</h2> <p>In the WhatsApp customer app, the purchase flow has the following steps:</p> <ol><li>Customer sends an order with selected products to the business or business identifies the products that the customer has shown interest to purchase. </li><li> After receiving the order or identifying the product, if a business accepts payment methods other than UPI, such as credit cards and payment wallets, etc. then business will send a message to the user to get their preferred payment method for the order. <div style="text-align:center;margin-bottom:20px;padding:20px"><img class="img" src="https://scontent-nrt1-1.xx.fbcdn.net/v/t39.8562-6/387124171_1078308003601084_1774404025771017675_n.png?_nc_cat=106&ccb=1-7&_nc_sid=f537c7&_nc_ohc=DmsRDbwn600Q7kNvgHHM78G&_nc_zt=14&_nc_ht=scontent-nrt1-1.xx&_nc_gid=AlaN2O6xxp7J8e4lKzWafEq&oh=00_AYBN5Cnr_m_CNU4ezemewG3nnWmTOcSTuJZd5Wc2rvquNw&oe=674C3423" width="200" alt="" /></div></li><li> When consumers want to pay using other payment method option, the business should generate the payment link by calling Payment Gateway by providing the unique "reference-id" and other information like amount, validity etc, then business can use the generated payment link to construct the order details message and send to the consumer. <div style="text-align:center;margin-bottom:20px;padding:20px"><img class="img" src="https://scontent-nrt1-1.xx.fbcdn.net/v/t39.8562-6/387176936_1058468541948735_2638528636968595331_n.png?_nc_cat=108&ccb=1-7&_nc_sid=f537c7&_nc_ohc=kVM5MRVwaQwQ7kNvgFdjmhb&_nc_zt=14&_nc_ht=scontent-nrt1-1.xx&_nc_gid=AlaN2O6xxp7J8e4lKzWafEq&oh=00_AYDGWFLHFfm07bjii6IF4e9vQNVjx3AHdUNhmQxMdKjaQg&oe=674C4BC9" width="200" alt="" /><img class="img" src="https://scontent-nrt1-2.xx.fbcdn.net/v/t39.8562-6/387841991_294802253336240_1543316033861124454_n.png?_nc_cat=102&ccb=1-7&_nc_sid=f537c7&_nc_ohc=JCiSLI_L_WkQ7kNvgEHg963&_nc_zt=14&_nc_ht=scontent-nrt1-2.xx&_nc_gid=AlaN2O6xxp7J8e4lKzWafEq&oh=00_AYCEyKvjbLtLFZiuDGV1UccV8papGDiAVc8ah-oRbU1Dag&oe=674C323B" width="200" alt="" /></div></li><li> When the consumer taps the Pay now/continue button, consumer will be redirected to the payment link within specially designed In-App browser to present with the list of supported payment options such as credit card, debit card, wallet or UPI apps.
