AMPscript Function Reference (Next)

The subset of AMPscript that Marketing Cloud Next supports — searchable and filterable, with the Core API version each function became available in and its Handlebars equivalent.

Next

Marketing Cloud Next runs a subset of the AMPscript surface that Engagement offers. This page lists only the functions the catalog marks as available on Next, together with the Core API version they arrived in and the Handlebars helper that covers the same job.

Availability is catalogued, behaviour is proven on Engagement

The API version column comes from the language catalog that also powers the SFMC Language Service and the ESLint rules. The Verified badge, however, means a runtime sweep on a live Engagement CloudPage — those linked pages document Engagement behaviour and have not been re-run on Next. Treat them as a strong indication, not as proof for Next.

Supported functions

Verified means the function completed a runtime sweep on a live Engagement CloudPage and has a reference page — the name links to it. A name without the badge is listed from the language catalog and has not been proven here; use ampscript.guide for those until a sweep reaches them.
