Meta Ads API Monitoring

Guardrly includes 50 semantic rules for the Meta Marketing API, covering campaigns, ad sets, audiences, pixels, and more.

Why Monitor Meta Ads Agents?

• Make too many API calls too fast
• Delete and recreate campaigns rapidly
• Modify audience targeting frequently

...can trigger account suspensions with no warning.
