Could you please provide documentation on the authentication mechanisms implemented within the fax callback (webhook)?
When passing the report destination details as:
'reports' => [
'type' => 'detail',
'report_destination' => [
[
'url' => "http://xxxx.yyy.zzz/callback"
]
]
]
What are the supported authentication mechanisms to implement on the report_destination url in order for a successful callback to occur (Basic Auth, oAuth 2.0, etc..)?
Thanks
