To add callout extensions in Google Ads with Claude or ChatGPT, connect your Google Ads account to PaidSync.ai and ask the assistant to add callout extensions, which show short selling points such as free shipping under your ad. You can attach callouts to one campaign or to the whole account. Each callout is capped at 25 characters, and PaidSync.ai previews the change before it is applied.
Callouts are short, non-clickable phrases that sit under your ad text, such as "Free Shipping" or "24/7 Support". PaidSync.ai has two tools for them, one for a single campaign and one for the whole account:
add_callout_extensions adds callouts to one campaign. Each callout can be up to 25 characters.add_account_callout_extensions adds callouts at account level, so they apply across the whole account instead of one campaign.list_account_extensions lists the account-level extensions already linked to the customer, so you can see what is in place first.list_account_extensions only reads your account. add_callout_extensions and add_account_callout_extensions change it.
| Tool | What it does |
|---|---|
| add_callout_extensions | Adds callouts to the campaign you named |
| add_account_callout_extensions | Adds callouts that apply to every campaign in the account |
| list_account_extensions | Reads the account-level extensions that already exist |
Pick the level on purpose. Account-level callouts show wherever no campaign-level callouts are set, so a short list of true claims works there, while a campaign-specific offer belongs on the campaign. Keep every callout under 25 characters or Google will reject it.
These steps use Claude to add callout extensions. PaidSync.ai also works in ChatGPT, and the prompts are the same.
Create a free account at paidsync.ai and approve Google Ads on Google's own sign-in screen. You do not need a developer token or a Google Cloud project, only a login with access to the account where you will add callout extensions.
Open Claude's connector directory, add PaidSync.ai and sign in. Ask "list my Google Ads accounts", then pick the account where you will add callout extensions.
Ask "List my account-level extensions and my campaign callouts." You see the callouts already running before you add more.
Give the assistant five to six short claims you can back up, such as free returns or same day dispatch, and say whether they go on one campaign or the account.
Ask the assistant to add them with the matching tool. It returns a preview with each callout and its level. Approve it and read the extension list again.
Read the extension list again after approval and check that each callout appears at the level you chose. A callout that does not show in the ad can still be under Google review.
Use these two prompts to add callout extensions, in this order.
list_account_extensions only reads your account, so the lookup before you add callout extensions changes nothing.add_callout_extensions and add_account_callout_extensions run as a preview by default, so you see the change before it is applied.add_callout_extensions and add_account_callout_extensions run.add_callout_extensions and add_account_callout_extensions can show a preview but not apply it. Tokens are encrypted at rest.add_callout_extensions and add_account_callout_extensions are applied, the change is logged, on a best-effort basis, with a before-and-after result.Every Google Ads tool PaidSync.ai offers is on the Google Ads MCP server page, including the tools used to add callout extensions.
Open Ads and assets in Google Ads, create a callout asset and link it to a campaign or the account. With PaidSync.ai, ask Claude or ChatGPT to add the callouts you listed and it previews them first.
Each callout can be up to 25 characters, which the tool states in its own input description. Longer text is rejected.
Yes. PaidSync.ai connects Google Ads to ChatGPT and to Claude, and the same tools run in both, so you can ask it to add callout extensions the same way you would in Claude.
A connected Google Ads account and the callout text, with each callout at 25 characters or fewer. For a campaign-level callout you also need the campaign. Account-level callouts need no campaign.
