In your project's How to integrate panel, there is a section called UTMs for Google Ads campaigns, with a ready-to-copy template. You only need to do this once, and it applies to the whole account:

  1. In Google Ads, click Admin (gear icon) and open Account settings.
  2. Expand the Tracking section and find the Final URL suffix field.
  3. Paste the code you copied and click Save.

That's it: every click now arrives with campaign, ad group and ad IDs, and sales appear in the UTM Purchases and UTM Revenue columns in Google Ads. If you prefer, you can also apply it per campaign under Campaign settings, Campaign URL options, Final URL suffix. The template uses Google's own variables, which are resolved at click time, so don't change the text.

You can also do this without opening Google Ads: in UTM Integrations, at step 3, click Include in Google Ads and choose In the entire account (recommended; campaigns with their own suffix don't inherit it, and the screen shows which ones) or In specific campaigns (up to 15 at a time).
