FAQ
Quick answers for developers and admins using the SAR ZONE WhatsApp API Middleware.
Where do developers send WhatsApp OTP requests?
Send requests to https://wa.sarzone.com/api/v1/whatsapp/send-template with the client middleware API key in the Authorization bearer header.
Do developers need Meta access tokens?
No. Developers use only the middleware API key and client code. Meta tokens stay encrypted inside the middleware.
How is an OTP verified?
Your own application generates and stores the OTP, sends it through this middleware, then compares the user-entered code with the stored code.
What if a message fails?
Open Message Logs and filter by failed status. The log keeps the Meta response and error message for troubleshooting.
Can one client use a different WhatsApp number?
Yes. Assign the client to the correct WhatsApp account in the client settings.
Can API keys be regenerated?
Yes. Admin users can regenerate a client API key from the client detail page.
