Certificate generator

Landscape Letter, bordered, with a seal, credential id and signature lines.

One template, three wordings. kind picks between a course or CEU certificate, a certificate of completion for work finished on a job, and a workmanship or product warranty — each with its own default heading and body. Everything else is the same layout, which is usually what you want: a company issuing all three should not have three different-looking documents.

The credential id in the footer is the field that makes a certificate verifiable. Put something you can look up in it, not a random number.

Up to three.

Issuing these in bulk

A course provider issuing certificates at the end of a cohort wants POST /v1/render/batch — up to 50 at a time, each with its own payload, with per-item errors returned inline so one bad row does not lose the run.
