"code": "Unauthorized",

"message": "{\"errorCode\":3,\"message\":\"Not logged in.\"}"

"code": "Unauthorized",

"message": "{\"errorCode\":3,\"message\":\"Session expired.\"}"

1
{
2
"code": "InvalidCredentials",
3
"message": "{\"errorCode\":3,\"message\":\"Invalid login or password.\"}"
4
}

2
"code": "Unauthorized",

"message": "{\"errorCode\":3,\"message\":\"Invalid API token.\"}"

If you encounter one of these errors, check if your login credentials are correct or make sure that a session ID/token was not deleted and is still valid.

"message": "User doesn't have required permission (expected one of: modify-objects, manage-objects)."
4
}

message field describes what permissions you need to have to make requests to this method.If you encounter this error, ask an administrator to check whether you have the required permissions and active them if necessary.
404 Not Found
This error happens when you try to make a request to a method that requires the ID of some item to be specified but the item with this ID doesn't exist. In such a case, a response will be similar to this:
1
{

"code": "ResourceNotFound",
3
"message": "Entity not found: User(42)"
