Up Tags API
Tags are custom labels that can be associated with transactions on Up. Within the Up application, tags provide additional insight into spending. For example, you could have a "Take Away" tag that you apply to purchases from food delivery services. The Up API allows you to manage the tags associated with transactions. Each transaction may have up to 6 tags. Tags are identified by their labels, which are unique strings, so the tag "Holiday" has also the `id` `"Holiday"`.
