Create an undeployed workflow from a portable export object, bare draft state, or JSON string. Requires workspace write access. The empty-state example creates a draft that needs runnable blocks before execution.
Mapped imports require a preview with the same choices, its previewFingerprint, and a stable requestId. Unresolved required configuration creates nothing. Identical retries return the committed result; reusing the ID with changed inputs returns 409. The result includes regenerated graph IDs and an operation receipt. Workspace folder trees exceeding 10,000 folders return 413.
OAuth scope: api:write.
/api/v2/workflows/importSend 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.
