Support Needed - autoCreate API

I tried to hit this API: https://api.zoom.us/v2/users

Payload:
{
“action”: “autoCreate”,
“user_info”: {
“email”: “jag*****@gml.com",
“type”: 1,
“first_name”: “Terry”,
“last_name”: “Jones”,
“password”: "
*********”
}
}

but i am getting this response"
{
“code”: 200,
“message”: “No privilege.”
}

So few questions,
1.Is a developer account needed to do this to create user API ?
2. Is my account not a developer account ?
3. How to get a developer account ?
4. Shd we need to buy a pro account, to use these API’s ?
