What the detail says

The detail explains the occurrence; it can read, for example:

• This contact has not allowed calls from your business. Send a call permission request first.

Handling it

The request is well-formed but its values are not accepted; fix them before retrying.

Example

{
  "type": "https://docs.nexafone.so/errors/whatsapp.call_permission_missing",
  "title": "Unprocessable Entity",
