Save an attribute for a traffic type ID. The attribute is created if it does not exist, and is overwritten completely with the provided attribute object if it does. This endpoint also accepts a PUT that behaves identically to the POST, but the POST is preferred. Use the PATCH endpoint for partial updates. The attribute ID must start with a letter followed by a combination of dashes(-), underscores(_), letters(a-z A-Z), or numbers(0-9).
