Get Signing Result

This endpoint allows the relying party (RP) to actively query the signing results and obtain the signed document after completion.

It is not recommended to use this endpoint for status polling as the webhook is more efficient. RPs do not need to invoke this API if the success signing webhook was captured.

Path

GET /sign-requests/:request_id/signed-doc

Headers

Name	Value
Content-Type	application/json
Authorization	<token>

Authorization token

RP should sign the signature parameter into a JWT token as authorization token.

• Token Type: Standard JWT (JSON Web Token)

• Payload:

  • exchange_code: The exchange_code returned when initiate sign request.

  • jti: Standard JWT ID, a unique identifier for the JWT, must be a UUID.

  • iat & exp: Standard Issued At / Expiration timestamp of JWT. Must issued within 2 minutes.

{
    "signed_doc_url": "XXXX",
    "signer_info": 
        {
            "signer_name": <Name as per the CN in the user certifiate>,
            "signer_partial_uinfin": "123A",
            "signed_at": <Timestamp of the user completing the sign request>
        }
    "exp": 1744190335
}

• signed_doc_url: Where you can download the signed document.

• signer_info : an object containing the following information:

  • signer_name : Name of the signer as per the user cert CN

  • signer_partial_uinfin : The last 4 alphanumerical value of the signer's NRIC

  • signed_at : Unix timestamp in milliseconds of when the user completed the sign request.

• exp: Expiration time (in UNIX second) of signed_doc_url .

Similar to the successful signing webhook, the signed_doc_urlwill only be valid for 2 minutes. RPs should download the document immediately for their own application. We do not recommend forwarding this URL to the user.
