| 404 | You’re trying to retrieve or work with a resource that does not exist. For example, you’re trying to get the customer with a specific ID, but a customer with such ID is not found in our records. Another example could be attaching a Plan to a product family, but the family you specified cannot be found. Also this status code is returned when there is no project with the project name. |
