Accepts an incoming WhatsApp call and joins its session from your WebRTC client.

Before you call

• Your organization needs a calling licence or add-on, and the API key's user needs permission to receive calls for the call.
• Send callId of the ringing call, with your WebRTC sdp and sdpType; deviceId is optional.
• The call must still be ringing; set reconnect to true only to rejoin a call you already answered.

How it works

• Answers the call on WhatsApp and marks it in progress; the response includes callStartedAt, chatId and the customer's details.
• Answering through the API does not assign the chat to you.
• Returns 422 if the call is not found, already answered or closed, its number is disconnected, or you are already on another call.
• With reconnect, only the user already on the call can rejoin.
• Browser (WebRTC) calls only: other calls return 400 Calling is not supported on this number.

Rate limit

• 60 requests per minute.
