API Overview - WhatsRB Cloud

Base URL: https://whatsrb.com/api/v1 — All requests require Authorization: Bearer YOUR_API_KEY

Resources

Connect and manage WhatsApp Business accounts via the official Meta API. Supports the embedded signup flow.

Send text, images, documents, and template messages to your customers at scale.

Create, sync from Meta, and send pre-approved message templates with dynamic variables.

Manage WhatsApp Web sessions for the session-based channel (no Meta approval required).

Monitor your plan limits, message throughput, and delivery metrics.

Every request must include your API key as a Bearer token:

Authorization: Bearer wrb_live_xxxxxxxxxxxxx

Generate your key from the WhatsRB Dashboard under Settings → API Keys.

Keep your API key secret. Never expose it in client-side code or public repositories.

    "waba_id": "123456789",
    "business_name": "Acme Corp",
    "status": "active"
  }
}

List endpoints include a meta key with pagination info:

{
  "data": [...],
  "meta": {
    "total": 42,
    "plan_limit": 10
  }
}

Errors return a JSON object with a human-readable error key:

{
  "error": "Business account not found"
}
