This is how to find why an ad was rejected in Microsoft Ads with AI: connect your Microsoft Ads account to PaidSync.ai, then ask Claude to list rejected ads and show why they were rejected, with whether each can be appealed. It only reads and changes nothing.
Rejections hide behind a status. These tools surface the reason and the offending term:
list_ms_ads_by_editorial_status lists the ads in an ad group that hold one editorial status, such as disapproved.get_ms_editorial_reasons returns the reason code, the offending term, where it sits and whether it can be appealed, for ads, keywords and assets.get_ms_editorial_evidence_bundle builds a portable record of why Microsoft rejected the entities.list_ms_ads_by_editorial_status, get_ms_editorial_reasons and get_ms_editorial_evidence_bundle only read your account, so you can find why an ad was rejected as often as you need.
| Tool | What it does |
|---|---|
| list_ms_ads_by_editorial_status | Finds the rejected ads |
| get_ms_editorial_reasons | Reads the reasons |
| get_ms_editorial_evidence_bundle | Builds a record to share |
An empty list is not proof that nothing was disapproved. The response names which of three cases applies. Read the offending term first, because the fix is often one word in the ad.
These steps use Claude to find why an ad was rejected in Microsoft Ads. PaidSync.ai also works in ChatGPT, and the prompts are the same.
Start at paidsync.ai, then link Microsoft Ads through Microsoft's own sign-in screen. Use a Microsoft login that can reach the account where you plan to find why an ad was rejected.
Add PaidSync.ai from Claude's connector directory and sign in. Ask "list my Microsoft Ads accounts" and choose the one to find why an ad was rejected in.
Ask for ads with a disapproved status in each ad group you care about.
Ask for the reasons and appeal status for those ads.
Edit the ad if the term is the problem, or appeal if the rejection looks wrong.
List the ads by status again after the fix and see whether the rejection is gone.
Use these two prompts to find why an ad was rejected in Microsoft Ads, in this order.

Not necessarily. The response says whether there were no ads with that status, no ads of that type or a failed read.
Yes. The tools used here only read, and PaidSync.ai reports on Microsoft Ads in the ChatGPT app as well as in Claude, so you can find why an ad was rejected there with the same prompt.
