/api/v2/workflows/{workflowId}/versions/compareCompare two deployment versions of the same workflow with workspace read access. The comparison excludes layout changes and withholds credential-bearing values while reporting their changes. Connections include stable block and port IDs. The combined snapshots and the comparison result must each fit within 16 MiB.
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.
