CMS Performance

The CMS Performance API enables teams to monitor their HubSpot hosted pages for issues that may impact the experience of visitors on the website. These metrics include things like uptime, status, 1xx- 5xx errors, cache hits, total requests, and median response times, making it easy for administrators to take action quickly in the event of a problem.

Example use case: You want to pull a list of pages that are resulting in 404 errors.
