# Generate Ad Previews

> Generates shareable Pinterest ad preview URLs for one or more ad groups

Generates shareable Pinterest ad preview URLs for one or more ad groups. Each URL opens in any browser without Ads Manager access and always reflects the current creative; no need to regenerate after edits. URLs expire after 30 days. Returns one preview per ad or product group promotion in each ad group.
