get https://api.certifier.io/v1/credentials//designs
Use this endpoint to list designs of a credential and available previews.
Important considerations
Preview URLs are immutable and versioned by a digest (hash) derived from:
- the design’s last update timestamp, and
- the resolved values of all rendered credential attributes
If you modify the design (layout,
fonts, colors, etc.) or any attribute value that appears in the design, the digest changes and previous preview URLs
will not automatically point to the new design. To get the newest preview after any change, you should fetch Get credential designs again and use the newly returned preview URL.
The digest-versioned URL (…/.png or .pdf) is permanent for that exact version. Treat it as cache-friendly and safe to store or share.
