During campaign creation, under Campaign URL | Tracking Parameters, use the following parameters:

kendall_source=applovin&utm_campaign={CAMPAIGN_NAME}&kendall_campaign={CAMPAIGN_ID}&kendall_adid={CREATIVE_SET_ID}

If you’re appending this to an existing value, then make sure you add a & before pasting the above string of text.

So, the Final URL might look similar to:

<https://yourstorefront.com?utm_source=applovin&kendall_source=applovin&utm_campaign={CAMPAIGN_NAME}&kendall_campaign={CAMPAIGN_ID}&kendall_adid={CREATIVE_SET_ID}>
