Send Carousel Messages

Build multi-card carousel messages directly in SendSeven and send them on WhatsApp, Messenger, and Instagram to showcase products and services.

Subtitle: Description or price (80 chars max)

Choose a category: Marketing or Utility. A carousel can never be Authentication

Give your template a name (lowercase, underscores only)

Text: Its own text per card, with numbered variables like {{1}}, {{2}}

Buttons: Up to 2 per card, at least one is required

The builder keeps the template valid while you work. Add sample values for your variables and they go along for review. The real values and the media are set per card when you send.

Templates are reviewed for compliance with WhatsApp's policies. Marketing templates have stricter requirements than utility templates.

Publicly accessible (no authentication required)

Promotional content in utility templates

Review Meta's feedback, adjust the carousel in the builder, and resubmit.

FAQ

Do I still need Meta Business Suite to build a WhatsApp carousel?

No. Since 28 August 2026 you build WhatsApp carousel templates directly in SendSeven, in the message composer, a campaign, or a flow. Meta still reviews the template, but you submit it from inside SendSeven and never leave the platform.

How many cards and buttons can a carousel have?

Up to 10 cards on WhatsApp, Messenger, and Instagram. WhatsApp carousel templates take up to 2 buttons per card, and at least one button is required. Messenger and Instagram allow up to 3 buttons per card.

Do Messenger and Instagram carousels need approval?

No. Both use generic templates, which send without pre-approval. You do need an open messaging window: the contact has to have written to you within the last 24 hours.

Can every card have its own image and text?

Yes. Each card carries its own image or video and its own text, with numbered variables such as {{1}} and {{2}}. You add sample values for the review, then set the real values and the media per card when you send.

Which category do I pick for a WhatsApp carousel?

Marketing or Utility. A carousel can never be an Authentication template. Marketing templates are reviewed more strictly, so keep promotional wording out of anything you submit as Utility.

Can I send the same carousel over RCS?

Yes. WhatsApp, Messenger, and RCS share one carousel format, so a carousel you have already built can also go out over RCS. RCS at SendSeven is in beta, available in Germany only and only to verified businesses, so access runs through [email protected].

How do I send a carousel through the API?

Post to /api/v1/messages/send/carousel with channel_id, contact_id, and a cards array. Each card takes a title, an optional subtitle and image_url, and its buttons. The endpoint accepts 2 to 10 cards and up to 3 buttons per card.
