First, take a look at the structure of a UTM key-value pair: utm_campaign={{campaign.id}} (just for example)
The utm_campaign is the key and campaign.id is the value that will populate the key once generated. Each platform has their own way of looking at these keys and find the value associated with it. So technically you can combine both strings with an ampersand (&) like this: your_utm={{your.value}}&parkour_utm={parkour.value}} As long as your UTM strings don’t share any key with our string, you’re fine!
