For create shared link API which business account supports advanced settings like password?

Thanks Greg.

I checked type of my account its a pro account and iam sending below request:

{
"path": "/Level1/Level2/Level3.txt",
"settings": {
"requested_visibility": "password",
"link_password": "abc",
"expires": "2017-12-15T15:50:38Z"
}
}

Still the endpoint gives below error:

{
"error_summary": "settings_error/not_authorized/",
"error": {
".tag": "settings_error",
"settings_error": {
".tag": "not_authorized"
}
}
}

What could be the reason for such behavior?

And if the Pro account expires does it still give the account_type as 'pro' by any chance?

Please guide me one this.

Thanks,

Akshata
