Media card carousel templates
Updated: Nov 4, 2025 Media card carousel templates allow you to send a single marketing template message accompanied by a set of up to 10 product media cards in a horizontally scrollable view:
When a user taps a media card’s URL button to buy a product, the URL mapped to the button is loaded in the device’s default web browser, thus taking the user out of the WhatsApp client experience. If you prefer to keep the user in the WhatsApp client, see Product Card Carousel Templates. Note that carousel cards are only available for marketing template messages.
Media cards
Carousel templates consist of a message body text and up to 10 product media cards. Each card in the template has an image or video header asset and can optionally include a body text and up to two buttons. Button combinations can be a mix of quick reply buttons, phone number buttons, and URL buttons. All cards defined on a template must have the same components.
WhatsApp users who place an order do so outside of the WhatsApp client, so no webhooks are triggered describing their order.
Creating media card carousel templates
Use the POST /<WHATSAPP_BUSINESS_ACCOUNT_ID>/message_templates endpoint to create a media card carousel template.Request syntax
It is necessary to define the exact number of product cards (minimum 2 and maximum 10) upon template creation. An approved template can only be used to send the same number of cards as defined during its creation. If any card in the carousel includes a card body text, then all cards must include a card body text to ensure consistent card heights.Request parameters

Request parameters
| Placeholder | Description | Example Value |
|---|---|---|
<BUTTON_INDEX>Integer | Required. Zero-indexed order in which button appears at the bottom of the template message. 0 indicates the first button, 1 indicates second button, etc.Note that if any buttons use variables, the type and order of buttons must match the type and order defined on the template, so you can’t use the index values to arrange the order of the buttons in the sent template. For example, if the template defines a phone number button first (which equates to index 0) and a URL button that supports a single variable second (which equates to index 1), if you attempt to send the template with the URL button index set to 0 , the API would return an error (“Parameter value for URL was expected but was not found”) because it’s expecting a button object with an index of 1 to be present in the post body payload. | 0 |
<CARD_BODY_VARIABLE>Object | Required if the template card body text uses variables, otherwise omit. Object describing a card body variable. If the template uses multiple variables, you must define an object for each variable. Supports text, currency, and date_time types.
