Assembly Status response
Transloadit uses a single response format for creating and querying Assemblies, appending responses to upload forms, and sending Notifications.
The following is a full example of a Transloadit response. Since files are processed in parallel,
the ordering for results does not necessarily follow the same order as uploads. There could
also be multiple results for a single upload. To match results with uploads, you can use the
original_id field, which is present in both items.

errorkey below is used instead of this key.errorIndicates an error status. This key is only present if the Assembly failed.
messageA human-readable message explaining the state of this Assembly. This is not always present.
assembly_idThe unique ID of this Assembly. You can store this in a database when an Assembly is created, and use it to match incoming Notifications.
assembly_urlThe unique URL used to query the current status of this Assembly.
assembly_ssl_urlThe unique URL used to query the current status of this Assembly, but ready to be used over SSL/HTTPS. All API requests that are sent to the
assembly_urlcan also be sent to theassembly_ssl_url.companion_urlThe URL to the Companion server that this Assembly may communicate with.
websocket_urlThe URL to a Websocket (uses Socket.IO) server from which you can get realtime status updates of this Assembly.
tus_urlThe URL to the tus server used by this Assembly for resumable uploads.
bytes_receivedThe number of bytes that have been uploaded to this Assembly so far. This is primarily used by clients to display upload progress.
bytes_expectedThe number of bytes that this Assembly expects to be uploaded.
bytes_usageThe total number of bytes that this Assembly processed that count towards your usage bill. The sum of
bytes_usageof all of your Assemblies equal your total monthly usage.client_agentThe user agent (browser) used by the uploader.
client_ipThe IP address of the uploader.
client_refererThe referrer URL of the uploader.
start_dateThe date and time at which upload started for this Assembly.
upload_durationThe time taken by the uploader to upload files, in seconds.
execution_durationThe time taken by Transloadit to execute this Assembly, in seconds.
fieldsA key/value map of any additional fields present in your form, for integrations can not use
<form>encapsulation (like Uppy).uploadsAn array of files uploaded for this Assembly. For more information, see the metadata docs.
resultsThe result files that Transloadit has produced so far. Each key of this object is the name of the Step that produced a particular file. As storage robots do not produce files, their Step names are not included here. In case of an
errormay contain partial results.
