# Cancel a running Assembly Cancels an Assembly that is still running. `DELETE` `https://api2.transloadit.com/assemblies/{assemblyId}` Cancels an Assembly (and upload if that is still in progress). The `assembly_ssl_url` field contains the unique URL returned when the Assembly was created. Cancellation sent to the API origin is forwarded to the owning uploader when it can be found. A running Assembly returns `ASSEMBLY_CANCELED`; an already finished Assembly retains its previous outcome. `ASSEMBLY_CANCEL_UNAVAILABLE` (HTTP 503) means the cancellation outcome could not be confirmed, not that cancellation definitely did not happen. Check the Assembly status before deciding whether to try again. The owner acknowledges cancellation after initiating job abortion. Persistence, notifications and accounting can continue afterward; the response does not wait for that bookkeeping. Use the returned `assembly_ssl_url` for a follow-up status read. Status at the API origin can lag while persistence finishes. `REQUEST_ABORTED` ends ordinary client waiting unsuccessfully, but work can still be active. An explicit cancellation therefore still contacts its owner. A terminal response does not promise that every worker has stopped or that all usage accounting has finished. If the owner is no longer available, an aborted or canceled outcome requires a final persisted snapshot. An ordinary cached status is not sufficient; a retained `REQUEST_ABORTED` outcome is not relabeled as canceled. > [!Warning] > Anyone who knows the `assembly_id` can issue this request. Treat Assembly IDs and > `assembly_ssl_url` values as secrets: do not publish them or share them with untrusted parties. > See [Are Assembly IDs secure?](/docs/faq/uuid.md). ## Request example Set `ASSEMBLY_ID` to your resource value without percent-encoding it. ```bash curl --fail-with-body -sS --request DELETE \ --url "https://api2.transloadit.com/assemblies/${ASSEMBLY_ID:?Set ASSEMBLY_ID}" ``` ## Path parameters * `assemblyId` (path segment), required. pattern: `^[a-z0-9]{32}$` ## Optional response query parameters * `callback` (JavaScript callback name). Wraps JSON responses in a JSONP callback. The callback name must match `^(?:_jqjsp[0-9]*|jQuery[0-9]+_[0-9]+)$`. Only the last occurrence is used; an empty value is ignored. Invalid callback names return HTTP 403. The transformed response uses HTTP 200. The callback is applied after response serialization. ## Request No additional request body or fields are required. ## Response Here’s an example response body: ```jsonc { "account_id":
