The following Macros are supported by Buzz. These macros may be included in [Creative Templates](🔗), the content of the [Creatives](🔗) or the `click_url` field of the Creative. Macros are case-sensitive and should be surrounded by double curly brackets on both sides to be properly recognized. For example, the macro `FOO` should be represented in the creative as `{{FOO}}`, not `{{Foo}}`.
