To change a campaign budget in Google Ads with Claude or ChatGPT, connect your Google Ads account to PaidSync.ai and ask the assistant to change the daily budget of a campaign, which sets the new daily amount in your account currency. A change of more than 50 percent needs an explicit confirmation, and every budget change returns as a preview first.

Which Tools Do the Work

The daily budget caps how much a campaign spends in a day. Claude reads the current figure first, then makes one change with one write tool:

get_campaign_details only reads your account. update_campaign_budget changes it.

How the Workflow Is Built

ToolWhat it does
get_campaign_detailsShows the current budget before you change it
update_campaign_budgetWrites the new daily budget after you confirm

The budget is in your account currency, and it must be greater than zero. The tool refuses to apply a change of more than 50 percent unless you confirm it, so a typo like 500 instead of 50 does not go through by accident.

How to Change a Campaign Budget in Google Ads With Claude in 5 Steps

These steps use Claude to change a campaign budget. PaidSync.ai also works in ChatGPT, and the prompts are the same.

1

Connect Google Ads to PaidSync.ai

Sign up at paidsync.ai, then connect Google Ads on Google's own sign-in screen. There is no developer token and no Google Cloud project. Use the Google login that has access to the account where you want to change a campaign budget.

2

Add PaidSync.ai to Claude

Install PaidSync.ai from Claude's connector directory and sign in. Ask "list my Google Ads accounts" and select the account to change a campaign budget in.

3

Read the current budget

Ask "What is the daily budget on my campaign Brand Search and how much did it spend yesterday?" Note the starting figure.

4

State the new budget

Tell the assistant the new daily amount. It runs update_campaign_budget as a preview and shows the old and new figures side by side.

5

Confirm the change

If the change is more than 50 percent, confirm it explicitly. The assistant then applies it and reads the budget back.

How to Check the Result

Ask for the campaign budget again and check it matches. Watch spend and the budget-limited share over the next days before moving it again.

Use these two prompts to change a campaign budget, in this order.

"What is the daily budget on my campaign Brand Search and how much did it spend over the last 7 days?"
Reads your account and changes nothing.
"Change the daily budget of Brand Search to 75 and show me the preview first."
Comes back as a preview and needs your confirmation.
