Common questions about ZapClaw.
ZapClaw is a lightweight WhatsApp message gateway that connects your business phone number to the official Meta Cloud API. It receives inbound messages and forwards them to your webhook URL, and lets you send outbound messages via a simple REST API.
Yes. ZapClaw uses Meta's official WhatsApp Cloud API. During the Embedded Signup flow, you'll connect your WhatsApp Business Account (WABA) and phone number. If you don't have one yet, the signup flow will guide you through creating it.
Coexistence mode allows you to connect a phone number that is already registered on a personal or business WhatsApp app. You can continue using WhatsApp on your phone while ZapClaw handles API messages in parallel.
When someone sends a message to your WhatsApp number, Meta delivers it to ZapClaw via webhook. ZapClaw then forwards the message payload to your configured webhook URL in real-time. If your endpoint is down, we retry up to 3 times with exponential backoff.

Yes. Access tokens are encrypted with AES-256-GCM, API keys are hashed with SHA-256, all communication uses HTTPS, and each customer's data is completely isolated (multi-tenant). We also validate Meta webhook signatures to prevent spoofing.
