§ Products

Four building blocks to prove the origin, integrity and date of your documents.

Use each service on its own or combine them, through the same API and the same conventions.

POST /v1/signatures

Electronic signature

Collect your users’ consent on a document, with a signing flow embedded in your application or driven entirely by API.

What you get

  • A PAdES-signed PDF, readable in common PDF readers
  • An evidence file tracing every step of the flow
  • Webhook notifications at every step

Use cases

  • Commercial contracts and quotes
  • Employment contracts and HR documents
  • Mandates, authorisations and membership forms

POST /v1/seals

Electronic seal

Automatically apply your organisation’s seal to the documents you issue, to guarantee their origin and integrity.

What you get

  • A PAdES-sealed PDF, on behalf of your organisation
  • A timestamp embedded in the seal, on request
  • Fully automated processing, with no human intervention

Use cases

  • Invoices and credit notes
  • Certificates, attestations and diplomas
  • Statements, reports and regulatory exports

POST /v1/timestamps

Timestamping

Prove that a file existed in a given form at a specific date, with a token issued by a time-stamping authority.

What you get

  • A token compliant with RFC 3161, detached or embedded in the document
  • The SHA-256 fingerprint of the timestamped file
  • A reliable date, verifiable independently of Docacert

Use cases

  • Proof of prior existence: source code, creative work, lab notebooks
  • Sealing of logs and log files
  • Timestamping documents before sending them

POST /v1/verifications

Verification

Check the validity of a signature, seal or timestamp, including on documents produced outside Docacert.

What you get

  • A clear status: valid, invalid or indeterminate
  • Details of the certificates and their chain of trust
  • An exportable validation report

Use cases

  • Checking documents received from partners
  • Verification at the entry point of a processing pipeline
  • Audits and compliance checks
