A key can have read, write, both or no permission for a module. Read does not include write, and write does not include read.
Modules
Missing permission
If the token is valid but the key lacks the required permission for the module, the API returns 403:If your key’s permissions change, the change takes effect when you get a new token. Log in again to apply it immediately.
API permissions are independent of the role permissions of the user sent in
X-UserID. The user determines on whose behalf operations are made and which records are visible (sharing codes).
