How do I pass UTM parameters to outbound Link Message URLs?
Category: Channels & embeds
Incoming UTMs on the Flow URL are captured for Console analytics. They are not copied onto outbound Link Message or Open Graph URLs unless you turn that on in Studio.
Open the Link Message (or Open Graph link), enable Forward UTM & click IDs, and publish. The destination then receives incoming utm_* keys plus ad click IDs (gclid, fbclid, msclkid, ttclid, wbraid, gbraid).
The toggle is off by default. Parameters already on the destination URL are kept. Empty values are skipped. Studio preview does not forward.
