Openapi Esignature

Openapi eSignature & time stamping

Bearer token required (see the openapi-auth skill). Signing and stamping are paid, legally binding actions — confirm with the user before submitting documents.

eSignature — https://esignature.openapi.com

eIDAS-compliant signatures with European legal validity.

Signature types

• POST /EU-SES — Simple Electronic Signature for one or more signers, secured via OTP
• POST /EU-QES_otp — Qualified Electronic Signature with remote OTP certificate
• POST /EU-QES_automatic — massive automatic QES (high volume)
• POST /EU-QES_eseal — qualified electronic seal (legal-entity seal)
• POST /verify — verify an existing signature

Certificates and results

• POST /certificates/namirial-otp / POST /certificates/namirial-automatic — purchase signing certificates
• GET /certificates, GET /certificates/{id} — list/inspect certificates
• GET /signatures — list signature processes
• GET /signatures/{id}/{actionType} — download the signed document, details, audit trail, or validated document
• DELETE /signatures/{id} — delete signature artifacts

Typical flow: ensure a certificate exists → create the signature request with the PDF and signer details → signers complete via OTP where applicable → download the signed document and audit trail.

Time Stamping (Marche Temporali) — https://ws.marchetemporali.com

Purchase qualified timestamps and apply them to documents (buy batches, stamp a document, verify stamps).

Legacy Digital Signature (ws.firmadigitale.com — Infocert/Aruba kits) is deprecated; use eSignature for new integrations.
