Remove an ad account from a website in Settings › Website › Connections: open the account, go to Danger zone and click Delete. To pause ClickGuard for a while instead, turn off the account's Click detection toggle. The account itself stays untouched on the ad platform.
Disconnecting an ad account removes it from one website in ClickGuard. ClickGuard stops protecting that account's campaigns for the website. Nothing changes in the account on the ad platform itself.
If you only want to stop ClickGuard for a while, you don't need to disconnect the account. Turn off its click detection instead:
ClickGuard stops seeing that account's clicks, and its ad spend no longer counts toward your usage. The account stays connected with all its settings, so you can switch click detection back on at any time.
You need permission to edit the website's connections. If the Delete button is greyed out, ask the workspace Owner.
Disconnecting an ad account doesn't revoke the sign-in access you gave ClickGuard on the ad platform. To remove it too, see How to remove ClickGuard's OAuth access.
