Variables

Rebrandly provides a set of perticular query parameter values that can be used as variables.
If you place a variable as parameter value this will be replaced with a run-time-computed value when the link is navigated to. Variables can be used both in Presets or while composing the link's destination query string.

The table below indicates or the available variables

Variable	Description
req.client.agent.browser.code	Browser (e.g. `firefox`)
req.client.location.country	Country code (e.g. `gb`, `it`)
req.client.agent.device.code	Device (e.g. `desktop`, `mobile`)
req.client.language	Lenguage (e.g. `it`, `en`)
req.client.agent.os.code	Platform (e.g. `macos`)
req.referral.hostname	Referral: contains the absolute or partial address from which a resource has been requested. (e.g. `yoursite.com`)
req.referral.origin.name	Source (e.g. `direct`, `other`)
req.timestamp	Timestamp in JSON format (e.g. `2022-11-18T15:12:27Z`)

These variables values must be enclosed in curly braces when used as parameter value and NOT URL-encoded.

For example, a query parameter like ?country={req.client.location.country} will replace the country code of the person who clicked navigated the short link.

A variable can also be concatenated to form a value:
?time=clickedAt_{req.timestamp}
