After 6 months of beta, carousel templates (multiple product cards inline) are now generally available globally. Supports up to 10 cards per template with image + button per card.Implementation example (full guide here):

typescript
await zavu.messages.send({
  to: "+14155551234",
  channel: "whatsapp",
  messageType: "template",
  content: {
    templateId: "tpl_carousel_products",
    carouselCards: [
      { imageUrl: "...", text: "...", buttonText: "Buy now" },
      // up to 10 cards
    ]
  }
})

Voice message templates rollout

Templates can now include pre-recorded audio segments. Max length: 30 seconds. Audio counts toward 4MB total template size.

Quality score thresholds tightened

Numbers with block rates > 0.5% (was 1%) now enter throttling. Recovery procedure: 14 days of clean sending typically restores score.

Indian pricing adjustments

Marketing: ₹0.45 → ₹0.55 (+22%)Utility: ₹0.13 → ₹0.16 (+23%)Authentication: ₹0.10 → ₹0.10 (no change)

Stricter compliance on Marketing templates

Templates with "limited time", "expires", "today only" language now flagged for manual review. Auto-rejection in some cases.

Sub-account billing API

Meta released APIs to programmatically separate sub-account billing for BSPs serving resellers. Zavu sub-accounts already support this.

The status field on inbound messages no longer includes "read" state. Use message.read event instead.Migration:

if (event.type === "message.read") {...}
