Limits in ChatGPT Ads

· An Ads API key is scoped to one ad account. Connect again for a second account.
· Reads never change anything. Pause and activate are the only writes, both run when enabled, and activating starts spend at the campaign budget.
· Archive, budget changes, spend limits, key creation and image uploads are not exposed. Image changes happen in Ads Manager.
· Disconnecting stops future gateway access. It does not undo a pause or activate that already ran.

What it looks like in Codex

Questions people ask first

How do I connect ChatGPT Ads?

Create an Ads API key in ChatGPT Ads Manager under Settings, open ChatGPT Ads in ApexGenius Connections, and paste it. ApexGenius checks it against the ad account before saving it encrypted.

Can my AI read spend and conversions?

Yes. Daily insights return spend, impressions, clicks and conversions by campaign, ad group or ad. Conversions count only the events attached to a campaign in Ads Manager.

Can my AI turn a campaign on or off?

It can pause or activate when the tool is enabled. Activating starts spend until someone pauses the campaign again.

Can it create ads or change budgets?

No. Creating campaigns or ads, editing budgets, spend limits, archiving and image uploads are not exposed through ApexGenius. Use Ads Manager for those.

Is this the same key as my website pixel?

No. The Conversions API key belongs to your site. The Ads API key is created separately in Ads Manager Settings and covers one ad account.
