can send customers <code>order_details</code> messages, then get notified about payment status updates via webhook notifications.</p> <div class="_57yz _57z1 _3-8p"><div class="_57y-"><p>This feature is only available for businesses based in Singapore and their Singapore customers.</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 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>. Now, with the Payments API, businesses can send customers a <em>bill</em>, so the customer can complete their order by paying the business without having to leave WhatsApp.</p> <div class="_57yz _57z1 _3-8p"><div class="_57y-"><p>Our payments solution is currently enabled by Stripe, a global third-party payments service provider. You must have a Stripe account in order to receive payments on WhatsApp. We expect more payment providers to be added in the future.</p> </div></div></div></div><div class="_4-u2 _57mb _1u44 _3fw6 _4-u8"><div class="_4-u3 _588p"><h2>How It Works</h2> <p>First, the business composes and sends an <code>order_details</code> message. An <code>order_details</code> message is a new type of <code>interactive</code> message, which always contains the same 4 main components: <strong>header</strong>, <strong>body</strong>, <strong>footer</strong>, and <strong>action</strong>. Inside the <code>action</code> 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 ID is used throughout the flow to track the order.</p> <p>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.</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> Customers send an order with selected products to the business either through simple text messages or using other interactive messages such as <a href="https://developers.facebook.com/docs/whatsapp/guides/commerce-guides/share-products-with-customers"> Single Product Message, Multi Product Message, and Product Detail.</a></li><li> Once the business receives the order, they send an <code>order_details</code> message to the user. When the user taps on <b>Review and Pay</b>, they will see details about the order and total amount to be paid. </li><li> When the user taps the <b>Secure Checkout</b> button, a secure in-app webview will appear for the user to pay for the order. </li><li> Once the payment has been confirmed, the business will be notified of the latest payment status using a webhook notification as shown in section 2 below. </li><li> Businesses can then send an <code>order_status</code> 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. </li></ol><p style="text-align:center;"><img class="img" src="https://scontent-hkg4-2.xx.fbcdn.net/v/t39.8562-6/10000000_1277882549479017_6190510402978338793_n.gif?_nc_cat=100&ccb=1-7&_nc_sid=f537c7&_nc_ohc=zbTtrgJWwRkQ7kNvgFVrb4e&_nc_zt=14&_nc_ht=scontent-hkg4-2.xx&_nc_gid=AIscpRsaa64NTnYAlQ4hJCc&oh=00_AYBnIYDtsstPTnqxWOM-yHrIkVs04Dv7xFTvyhfIpNN6iw&oe=67472E95" height="560" alt="" /></p></div></div><div class="_4-u2 _57mb _1u44 _3fw6 _4-u8"><div class="_4-u3 _588p"><h2 id="link-your-payment-account">Link Your Payment Account</h2> <p>To receive payments on WhatsApp, you must add a <em>payment configuration</em> to your WhatsApp Business Account. You can create a payment configuration for your WhatsApp Business Account using the 'Direct pay methods' page under 'Singapore' in your <a href="https://business.facebook.com/wa/manage/home">WhatsApp Business Manager</a> as shown below.</p> <p style="text-align:center"><img class="img" src="https://scontent-hkg4-2.xx.fbcdn.net/v/t39.8562-6/342615173_253770610436387_7773015588352851484_n.gif?_nc_cat=106&ccb=1-7&_nc_sid=f537c7&_nc_ohc=ou9f8_1_x4gQ7kNvgEKct_N&_nc_zt=14&_nc_ht=scontent-hkg4-2.xx&_nc_gid=AIscpRsaa64NTnYAlQ4hJCc&oh=00_AYAJS9CV0zCvE4edMgCJzg9ZIjpyd1i1fNXF8-ZabgKYOQ&oe=67474816" alt="" /></p><div class="_57yz _57z1 _3-8p"><div class="_57y-"><p>Only the business that owns the WhatsApp Business Account can connect their Stripe account to a payment configuration. We only support Embedded and Direct signups at this time.</p> <p>In addition, only Admin and Financial Editors of such a business can connect the Stripe accounts.</p> </div></div><p>A payment configuration allows you to link your Stripe account to WhatsApp. Each payment configuration is associated with a <em>unique name</em>. As part of the <code>order_details</code> message, you can specify the payment configuration to use for a specific checkout. WhatsApp will then generate a payment link using the associated Stripe account. This link opens up in an in-app webview so consumers can pay for their order.</p> <p>After linking your Stripe account, you must integrate with the Payments APIs below. This will allow you to send an <code>order_details</code> message to customers with the payment configuration to receive payments.</p> </div></div><div class="_4-u2 _57mb _1u44 _3fw6 _4-u8"><div class="_4-u3 _588p"><h2>Integration Steps</h2> <p>The steps outlined below assume that the business already knows what the user is interested in through earlier conversations.
