Most PDF APIs stop at the file. Certly returns a branded certificate plus a hosted verification page, a QR code, and a tamper-proof ID, in a single call. Priced by volume, not per recipient.
POST the recipient, course, and date to the API, with your template.
Receive a branded PDF, a tamper-proof credential ID, and a hosted verification link with a QR code.
The recipient shares the link or scans the QR. Verifiers confirm it is authentic in one click, no login.
Developers call the API directly. No-code teams connect it in Make, Zapier, or Bubble in a few clicks. Once it is wired to your course, event, or training tool, every certificate is issued and made verifiable automatically. No one runs anything by hand.
