Get Export Status
Poll the status of an asynchronous export task.
Returns is_terminal=False while the export is still running (with a
suggested retry_after_seconds); is_terminal=True once it
completes or fails. The signed url is set on completion.
The canvas_id in the path must match the canvas that the task
targets — mismatches return 404 (we don’t leak which canvas a task
actually belongs to).

Headers
Calendar-dated API version pin. New integrations should pin 2026-05-01 to opt into the newest response shapes. For back-compat the server also accepts requests with no header and resolves them to the current default (today: 2026-04-12); that default advances on each sunset date. Any unsupported value returns 400 unsupported_version.
2026-04-12, 2026-05-01 "2026-05-01"
Path Parameters
Prefixed cvs_ wire ID (Crockford base32 body) — the canonical, recommended form. For back-compat, a bare UUID string is also accepted in both path parameters and JSON request bodies (older integrations that stored raw UUIDs keep working). Both are permanent, supported inputs.

Query Parameters
Export task ID returned by /export when status='in_progress'.
Response
Successful Response
Response for GET /canvases/{id}/export-status.
The export task ID.
queued, running, completed, or failed.
True when status is completed or failed.
Prefixed canvas identifier the export targets.

Full URL to open the source canvas in the Moda editor.
Delivered format — png, jpeg, pdf, pptx, or zip. Multi-page PNG/JPEG exports surface as zip (per-page files inside).
Signed download URL once the export completes. null while running.
Failure detail when status='failed'.
Typed failure code when status='failed' and the export lane reported one — e.g. no_renderable_content (terminal: the canvas rendered 0 pages, so a retry without changing the canvas cannot succeed) or native_export_declined (terminal: the render lane has no path for this content). null when no typed code is available.
Set when status='failed': false for terminal render failures (retrying the same canvas cannot succeed — fix the content first), true for transient faults where a fresh export attempt can succeed. A failed status is itself terminal for THIS task; retryable says whether starting a new export is worthwhile.
Set while is_terminal is False — suggested poll interval.
Total page count for the source canvas (set on completion).
Quality caveats about the delivered file, set once status='completed' — the same list the synchronous export response would have returned. Empty while running, on failure, and whenever nothing was degraded.
