Extending a PDF for long term archival (LTA)

Make a POST request to https://id.eideasy.com/api/signatures/extend with the following request body:

{
  "secret": "{{secret}}",
  "client_id": "{{client_id}}",
  "signed_file": {
    "fileName": "dummy-filename.pdf",
    "mimeType": "application/pdf",
    "fileContent": "{{signedFile}}"
  },
  "signature_form": "PAdES",
  "signature_profile": "PAdES_BASELINE_LTA",
  "validate_signature_extension": true
}

fileContent - a base64 encoded PDF document.

validate_signature_extension - if set to true, the request will succeed only if all of the signatures in the document can be successfully extended to the requested signature_profile. If set to false, the request will succeed even if some of the signatures cannot be extended.

Note: Don’t forget to set header Content-Type: application/json
