Validate destination mappings and configuration with workspace write access, without creating a workflow. The result reports readiness, unresolved fields, discovery instructions, and a fingerprint for mapped import with the same choices. Imported provenance never authorizes or queries a source workspace.
OAuth scope: api:write.
/api/v2/workflows/import/previewSend 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.
In: header
Request examples use an API key. For OAuth, replace the X-API-Key header with Authorization: Bearer YOUR_ACCESS_TOKEN.
