Frequently asked questions
Is Wathook an official Meta service?
No. Wathook is an independent service that connects through WhatsApp's linked-device (WhatsApp Web) protocol. It is not affiliated with or endorsed by Meta or WhatsApp, and it is not the official Cloud API. Account restrictions or protocol changes can affect availability.
Do I need message templates or an approval to start?
No template approval flow is involved. Once your number is paired with a session, you can send and receive through the API. Use it only with people who have agreed to hear from you; WhatsApp can restrict accounts that behave like spam.
How do I connect my WhatsApp number?
Open your session and scan the QR code from WhatsApp → Linked devices on the phone that owns the number, or use a pairing code when available. If WhatsApp asks for passkey linking, Wathook cannot complete it; restart the session to try again.
Can I keep using WhatsApp on my phone?
Yes. The API works as a linked device, so the phone and WhatsApp Web keep working alongside it. WhatsApp may occasionally reset linked devices and ask you to pair again.
What can I send?
Text, images, video and documents (PDF, spreadsheets and other files). You can also read available chats, groups and messages, and receive incoming messages, delivery and read updates and session changes by webhook.
How does pricing work?
You pay for each WhatsApp session (one number) on its own, for 1, 3 or 12 months, and each session has its own expiry date. There are no per-message fees. The session is created once your payment is confirmed; nothing renews automatically.
Is message delivery guaranteed?
No. Each message is sent immediately and the response reports the result from WhatsApp. Sent is not a delivery receipt: delivered and read updates arrive later by webhook. A timeout may still have sent the message. Wathook does not resend it or block your next request.
Can I resell it under my own brand?
Yes. Partners buy prepaid session credits in the dashboard. The Manager API creates sessions from those credits and deletes owned sessions. Give each client only its own session token.
