Before you can request a document to be timestamped, make sure the feature is activated on your account.
To request a timestamp, send a multipart/form-data request to POST /v1/timestamp/pades and pass the document in the file argument.
Note that we accept only PDF input format in a maximum size limit of 25MB.
curl
https://api.universign.com/v1/timestamp/pades \
-F file=@MyDocument.pdf
The request returns a 200 response that contains a PAdES document timestamp compliant with the ETSI EN 319 142-3 standard.
