Campaign / UTM Parameters
Attach plan-controlled campaign values without rebuilding every destination URL.
Configuration
Add parameter name/value pairs in the authenticated link form or the API parameters array. Common names include utm_source, utm_medium, and utm_campaign.
Resolution
A value replaces a matching placeholder in the destination; otherwise it is appended or merged into the query string. The same parameters are also applied to mobile attempts and fallbacks.
Limits
The active plan controls whether campaign parameters are retained. Treat URLs as public: never place tokens, emails, or private identifiers in campaign parameters.
