DSS offers  REST and SOAP WebServices  with the following functions :

• Document validation
  • Validate a document (signed or timestamped);
  • Retrieve an original signed document.
• Certificate validation
  • Validate a certificate.

These services hide the signature complexity (CAdES, PAdES, XAdES, JAdES, ASiC) and made integration easier.

Since DSS v5.6, the REST WebServices are compliant with OpenAPI Specification.
