Why WhatsApp is Non-Negotiable in 2026

With over 3 billion active users, WhatsApp isn’t just a messaging app; it’s the primary operating system for commerce in many regions. For enterprises, the WhatsApp Business API offers capabilities far beyond the standard app.

Understanding the 24-Hour Session Window

One of the most critical concepts is the session window. When a user messages you, a 24-hour countdown begins. In this window, you can send free-form messages. Once it closes, you must use pre-approved Template Messages to re-engage.

Template Messages: The Key to Re-engagement

Templates are strictly regulated by Meta to prevent spam. They fall into categories like:

  • Utility: Order updates, account alerts.
  • Authentication: OTPs, login codes.
  • Marketing: Promotions, product launches (requires opt-in).

Getting the Green Checkmark

The coveted green badge signals trust. To qualify, your brand must be notable (often requiring press coverage) and your WhatsApp account must be verified in the Meta Business Manager. Dexra’s onboarding team helps guide you through this verification process.

Integrating with Dexra

Dexra’s API abstraction handles the complexity of Meta’s graph API. You simply connect your number, and we handle webhook events, media storage, and session management automatically.
