What HTTP status code should my webhook server return?

Your server should return a `200 OK` or `204 No Content` HTTP response code promptly (within 5 seconds) to acknowledge successful receipt.

Can I replay a webhook event if my server was down?

Yes! You can navigate to the Webhook Logs in your Chatofy dashboard, locate any failed delivery attempt, and click "Replay Event" to resend it.

Can I filter which events are sent to my webhook URL?

Yes. You can subscribe to specific event categories (e.g. only inbound customer messages or only delivery status receipts) to reduce unnecessary traffic.

Do I need an existing WhatsApp Business API account?

No, you can apply and set up your WhatsApp Business API account directly through Chatofy during onboarding.

Can I use my existing WhatsApp number?

Yes, you can migrate an existing WhatsApp number to the API with Chatofy's WhatsApp Coexistence architecture without losing your chat history.

Where can I find the OpenAPI specification for Chatofy?

Chatofy publishes OpenAPI 3.0 specifications at https://chatofy.in/openapi.json and https://chatofy.in/api/openapi.yaml.
