Declines an incoming call or ends an active call.

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 the callId of a call that is still ringing or in progress.

How it works

• Hangs up the call on WhatsApp and updates the call in the chat.
• The response's callStatus is REJECT for a declined ringing call and END for an ended call.
• Returns 422 if the call is not found, already closed, its number is disconnected, or another user is on the call.
• Browser (WebRTC) calls only: other calls return 400 Calling is not supported on this number.

Rate limit

• 60 requests per minute.
