Replay Assembly Notification
https://api2.transloadit.com/assembly_notifications/{ASSEMBLY_ID}/replay
Warning
assemblies:write
scope.Replays an Assembly Notification, sending the POST request containing the
Assembly result JSON again to the notify_url
that was specified when the
Assembly was created.
POST fields
- Passing
signature
is required. For more information, please check Signature Authentication. - Passing
params
is required. It should contain a JSON encoded object with the keys as shown in the table below.
Supported keys inside the params
field
auth
— requiredobject
Contains at least your Transloadit Auth Key in the
key
property.If you enable Signature Authentication, you must also set an expiry date for the request in the expires property:
{ "key": "23c96d084c744219a2ce156772ec3211", "expires": "2009-08-28T01:02:03.000Z" }
We strongly recommend including the
nonce
property — a randomly generated, unique value per request that prevents duplicate processing upon retries, can aid in debugging, and avoids attack vectors such as signature key reuse:{ // … "nonce": "04ac6cb6-df43-41fb-a7fd-e5dd711a64e1" }
The
referer
property is a regular expression to match against the HTTP referer of this upload, such as"example\.org"
. Specify this key to make sure that uploads only come from your domain.Uploads without a referer will always pass (as they are turned off for some browsers) making this useful in just a handful of use cases. For details about regular expressions, see Mozilla's RegExp documentation.
The
max_size
property can be used to set a maximum size that an upload can have in bytes, such as1048576
(1 MB). Specify this to prevent users from uploading excessively large files.This can be set as part of the Assembly request or as part of the Template.
The file size is checked as soon as the upload is started and if it exceeds the maximum size, the entire upload process is canceled and the Assembly will error out, even if it contains files that do not exceed the
max_size
limitation.If you want to just ignore the files that exceed a certain size, but process all others, then please use 🤖/file/filter.
