Transloadit

Retrieve Assembly Notifications

Lists the original Assembly Notification and saved manual replay records.

GEThttps://api2.transloadit.com/assembly_notifications/{assemblyId}

Returns Webhook delivery details without additional authentication.

The list contains the original Notification record, when present, and saved manual replay records, ordered by their start time. Automatic retries update the same record; they do not produce separate entries or a history of every delivery attempt.

Check the recorded status and response_code to determine the delivery outcome. A 2xx response_code acknowledges delivery; replay API success alone does not confirm delivery.

Notification list entries do not expose the replay response’s notification_id, and concurrent replays can share a start timestamp. An older successful record does not confirm delivery of the replay you just requested. To identify a particular replay, include a unique application-defined marker in the query string of an explicit notify_url and match the recorded url with your receiver’s delivery logs. Use a non-secret marker; URL fragments are not sent to your receiver.

Request example

Set ASSEMBLY_ID to your resource value without percent-encoding it.

curl --fail-with-body -sS --request GET \
  --url "https://api2.transloadit.com/assembly_notifications/${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:

  "notifications": [
    {
      "assembly_id": "0fce5b1063e611e88d8eb130f7921d8a",
      "error": null,
      "response_code": 204,
      "response_data": "",
      "start": "2026-09-12T10:00:00.000Z",
      "status": "successful",
      "url": "https://example.com/webhooks/transloadit"

FieldType and description
notifications[].app_id
null | string

The workspace identifier, retained under the historical field name app_id.

string

The Assembly whose Notification was delivered.

notifications[].duration
number | null

Elapsed delivery time in seconds, including automatic retry attempts and the delays between them.

notifications[].error
null | string

The recorded delivery error, when available. A failed delivery need not include this field; inspect status and response_code as well.

notifications[].response_code
number | null

The recorded HTTP response status from your Notification URL. A 2xx response acknowledges delivery; this is not the status of the API request that lists or replays Notifications.

notifications[].response_data
null | string

The recorded response body from your Notification URL. Long responses are truncated.

notifications[].start
null | string

When delivery started, as a GMT date string. Automatic retries retain the original start time.

notifications[].status
"error" | "processing" | "successful" | null

The delivery state recorded for this Notification, including its automatic retries.

notifications[].url
null | string

The URL used to deliver this Notification.
