Its editor offers drag-and-drop design, branding, dynamic fields, and 200+ templates. Teams can issue personalized credentials in bulk from CSV or Google Sheets data, or through the API. Each credential receives a unique verification URL and dynamic QR code, and recipients can check it from a printed copy. Teams can revoke and re-issue credentials, with status updated on verification pages. Recipients can share credentials to LinkedIn, X, and Facebook or add them to LinkedIn’s Licenses and Certifications section.
