# Object tags

Tag attributes allow you to match Treezor objects with objects stored in your own databases. These attributes are:

  • Strings (max 250 characters)
  • Always in the API's responses
  • Named as a concatenation of the object's class and the word "Tag" (camelCase)

Here are a few examples of tag attributes: userTag, cardTag, payinTag, walletTag.

Best practice – Tags must:

  • Be unique. Use a tagging convention that enforces uniqueness as to avoid tag collisions
  • Use alphanumeric characters plus / ! - _ . * ' ( ). Using other characters can have unexpected consequences.
