Securitygrens

This documentation covers the stable external integration contract only. Platform internals, administrative routes, schema-level discovery, and partner-only capabilities are intentionally withheld from the public surface.

Routenamen, tokenvoorbeelden en transportdetails blijven in canoniek Engels zodat ze exact overeenkomen met het publieke contract.

Sandbox environment

Issue short-lived sandbox tokens (aud=sandbox) and route the entire v2026.4 surface to deterministic mock connectors at https://sandbox-api.knogin.com. Dual gate prevents leak between sandbox and live.

POST

/v1/platform/apps/{client_id}/sandbox-token

Issue a sandbox token

Mints a short-lived sandbox token (aud=sandbox) for the requested app. Sandbox tokens route to deterministic mock connectors at https://sandbox-api.knogin.com.

Host: https://auth.knogin.com
Auth: Bearer token
Doelgroep: Klantadmins
Stabiliteit: Stabiel

Requires the `argus:platform:admin` scope to mint sandbox tokens. Sandbox tokens themselves cannot mint further sandbox tokens.
`ttl_seconds` is clamped to the inclusive range [60, 86400]; values outside are normalised before signing.
Optional `scenarios` array pins the sandbox to specific scenario IDs so the same client_id consistently sees the same canned data.
The returned token carries `aud=sandbox`. Use it against the sandbox host `https://sandbox-api.knogin.com`; live hosts reject sandbox tokens with 403.
Sandbox tokens carry the issuing tenant's `tenant_id` and `organization_id` so audit and rate-limiting remain tenant-scoped.

Auth: Bearer token
Doelgroep: Externe integrators
Stabiliteit: Stabiel

Requires a sandbox token (`aud=sandbox`); a live token returns 403.
Hosted on `https://sandbox-api.knogin.com`; calling the same path on the live API host returns 404.
Scenario IDs returned by this endpoint are the canonical values accepted by the `scenarios` field on `POST /v1/platform/apps/{client_id}/sandbox-token`.
Sandbox responses also carry `X-Argus-Sandbox: true` so partner debugging tools see at a glance that the response is synthetic.

GET

/v1/discovery/data-schemas

List visible data schemas for the caller

Reflective endpoint listing the JSON schemas the caller's tenant and clearance can reach right now, with optional COI federation.

Host: https://api.knogin.com
Auth: Bearer token
Doelgroep: Externe integrators
Stabiliteit: Stabiel

Requires the `argus:discovery:read` scope on a bearer token.
Tenant scoped: results are filtered by `tenant_id` and `organization_id` from the auth context. Schema visibility is additionally clamped against the caller's `secrecy_level` clearance.
Optional query parameter `include_federated=true` extends the listing with upstream sources reachable via approved Communities of Interest (COI) channels.
Optional query parameter `secrecy_max=` clamps results to a clearance level; the default is the caller's own clearance.
Each schema entry advertises its canonical `schema_url` under `/.well-known/schemas/{id}.json` for offline contract pinning.
Audit event `discovery.schemas.read` is emitted on every call.
