I’m trying to create a signup call to the Auth0 API, but I keep getting ‘connection not found’ when I use Postman to submit the call.

This is the URL I am using:  
https://{my domain}/dbconnections/signup

And this is the data I’m sending:  
{  
“client\_id”:“{my client id}”,  
“[email":"john@jk950.com](mailto:email%22:%22john@jk950.com)”,  
“password”:“test1234”,  
“connection”:“con\_{16 digit alphanumeric code}”,  
“username”:“jk950”,  
“given\_name”:“John”,  
“family\_name”:“Doe”,  
“name”:“John Doe”,  
“nickname”:“Johnny”  
}

Returns:  
{  
“error”: “connection not found”  
}

Hi @kingjon90, I believe the `connection` parameter should be the name of your connection, not the connection\_id.

Let me know if that works!
