List workflow versions

GET/api/v2/workflows/{workflowId}/versions

List saved deployment versions, newest first, with workspace read access. Each version pins an immutable graph; its name and release note can be updated.

OAuth scope: api:read.

Authentication

Send a personal or workspace API key in X-API-Key. See key types and access; operations that reject workspace keys say so in their description.

Send X-API-Key in the request header.

Alternatively

Send a Sim OAuth access token in Authorization: Bearer. See OAuth authentication and scopes.

Authorization: Bearer YOUR_ACCESS_TOKEN

Required scopes: api:read
