Writes to existing campaigns: an owner switch per account

What it does

Three independent conditions must hold for a write to an existing campaign: the ad account is on the server's list of accounts allowed for writes, the owner has turned on “Writes to clients' existing campaigns” for that account with the second factor, and the client's policy allows the change. Each is checked both in the database and in the application.

Campaigns the service created itself are writable without the switch. Shared Google budgets are refused, because a change would affect other campaigns. Turning the switch off stops queued changes for that account.

Why it helps

• Start safely: explore and propose without risk to live campaigns.
• Enable writes account by account as trust grows.
• A clear, logged owner decision for every account.

How to set it up

1. Open Integrations and find the ad account card.
2. As the owner, turn on writes to existing campaigns and enter the one-time code.
3. Review the client's policy level shown next to the switch.
4. Propose changes to existing campaigns as usual.
