WhatsApp API pricing is different from traditional SMS. It’s based on 24-hour conversation sessions. Here is everything you need to know to budget effectively.

Two Main Cost Components

  1. Meta Conversation Charges: Paid directly to Meta (usually via your BSP).
  2. Platform Fees: Paid to your solution provider (like Text-World) for the software interface.

Understanding Conversation Categories

Meta charges differently based on who starts the conversation and the intent:

  • Marketing: Promotional offers (Highest cost).
  • Utility: Transaction updates like shipping alerts.
  • Authentication: OTPs for login.
  • Service: User-initiated support conversations (Lowest cost, sometimes free).

The 24-Hour Window

Once a conversation starts, a 24-hour window opens. You can exchange unlimited messages of that category within this window for a single charge.

Free Entry Points

Conversations starting from Click-to-WhatsApp ads or Facebook Page buttons are currently free for the first 72 hours.

Tip for Cost Saving

Focus on encouraging user-initiated conversations (Service category) by using clear CTAs on your website and social media.
