Kolleges Developers

Automate certificate and digital badge issuance via API. Issued credentials are preserved forever as Open Badges 3.0 / W3C Verifiable Credentials.

15-minute tokens

OAuth2 client_credentials — no long-lived static keys. Exchange your client_secret for a 15-minute ES256 token and use that.

Idempotent issuance

Safe retries with Idempotency-Key. Single or batch, all through one endpoint.

Permanent credentials

Issued VCs are preserved forever as did:key · VC-JWT — verifiable even after the user or club is deleted.

Always-live spec

The API reference renders the OpenAPI the server emits in real time — zero doc drift.

Two APIs

Pick the API that fits your use case — each reference renders the OpenAPI the server emits in real time.

Open API v2 · Direct issuance

For customers using Kolleges directly. Issue, look up, and revoke your own club’s certificates and badges.

Partner API · Channel partners

For channel partners that operate multiple clubs on others’ behalf. Delegated per-club issuance under a partner scope.
