Restamps

The signatures of a diploma must remain verifiable long after the certificates that created them expire. Each signed XML file therefore carries an archive timestamp (ICP-Brasil AD-RA policy), whose own validity ends when the certificate of the timestamp authority expires. Before that happens, Digiploma restamps the file (renotarização): it adds a new archive timestamp, which extends the preservation of the signatures.

This happens automatically, for the signed XML files of:

• diplomas (the diploma XML and the academic documentation XML);
• final academic transcripts and second copies (not partial transcripts);
• curriculums;
• registration requests (the diploma XML signed by the registrar), only when the instance enables it.

When a document is concluded, Digiploma creates a restamp record with the expiration date of its archive timestamp. A daily job, at night (Brasília time, by default), restamps the files whose expiration is less than 180 days away (by default), then creates a new record for the new expiration date. On premises, these defaults are configurable. A restamp that fails is retried on the following days. Restamping is on by default; the instance administrator can turn it off for an organization. Diploma revalidation explains why it is needed, with a diagram of the cycle.

List restamps

GET /api/restamps returns a page of the organization's restamp records. It requires the ViewRestamp permission.

Parameter	Description
DocumentTypes	Document types, repeatable: Degree, AcademicDocumentation, Registration, AcademicTranscript, Curriculum.
Status	Restamped (applied), NonRestamped (pending) or WithError.
RestampFilterField	The date that StartDateUtc, EndDateUtc and the order refer to: ExpiringDate (default), the expiration of the archive timestamp, or RestampDate, when it was restamped.
StartDateUtc, EndDateUtc	From StartDateUtc (inclusive) until EndDateUtc (exclusive).
Q	Text in the identifier.

Besides the paging parameters.

Field	Description
id	The record.
documentType, documentId	The document. For Degree and AcademicDocumentation, documentId is the diploma's id.
identifier	The student's CPF, or the code of a curriculum.
archivingExpiringDate	When the current archive timestamp expires.
date	When the file was restamped; null while pending.
errorReason	The error, if the record could not be created or the restamp failed.
creationDate, updateDate

Webhooks

RestampCreated, RestampUpdated, RestampApplied and RestampApplyingError report the progress of each record, but they are disabled by default and are sent only when the instance enables them. See Webhooks.
