Obtain NOM151 certificate

In order to access all the properties of a document, as well as its list of versions and signers, it is necessary to obtain it through the document id, performing a GET to /documents/:document_id.

The attribute we need to check to perform the ASN1 file download process is adv_str_constance within the file {} properties.

If this variable has values we can proceed to generate the file, for this we must add the following value data:application/octet-stream;base64, plus the value found in adv_str_constance. Once having the complete string, the extension of the file for download is attached, which is .asn1, leaving a final string like this:

data:application/octet-stream;base64, + adv_str_constance + asn1

curl  --location --request GET 'https://sandbox.api.cincel.digital/v1/documents/0' \  --header 'x-api-key: my_secret_key' \  --header 'Content-Type: application/json' \
