Here are the steps to send and verify credentials using OpenID for Verifiable Presentation (OID4VP).

Step 1: Get the API Key​

To get the API key contact support@igrant.io.

Step 2: Create Verification Request (Verfier/Relying Party)​

Copy the code block below to create the verification request. Execute the API available here.

Filter by credential type
{
  "presentationDefinition": {
    "id": "046acbac-ea8d-4f95-8b57-f58dd178132b",
    "format": {
      "jwt_vc": {
        "alg": [
          "ES256"
        ]
      },
      "jwt_vp": {
        "alg": [
          "ES256"
        ]
      }
    },
    "input_descriptors": [
      {
        "id": "ef91319b-81a5-4f71-a602-de3eacccb543",
        "constraints": {
          "fields": [
            {
              "path": [
                "$.type"
              ],
              "filter": {
                "type": "array",
                "contains": {
                  "const": "VerifiableLegalPersonalIdentificationData"
                }
              }
            }
          ]
        }
      }
    ]
  }
}

The presentation definition provided adheres to the specifications outlined in the DIF Presentation Exchange standard, as detailed here.

Step 3: Receive Verification Request (Holder)​

The holder wallet can receive the verification request in the following ways:

  • Using your Data Wallet (or any other Digital Wallet: From the response, use the vpTokenQrCode and generate the QR code here using plain text option
  • Using your Organisation Wallet (or similar).

Step 4: Send and Receive Verifiable Presentation (Holder)​

The holder wallet accepts (consents) to send the requested credentials.

Step 5: Send and Receive Verifiable Presentation (Verifier/Relying Party)​

  • The Verfier (Relying Party) receives the requested credentials and can verify it. They may read the received credential by executing the Read Verification History API.
  • From the response received, the vpTokenResponse can be decoded using JWT.IO Decoder.
  • From decoded response, the verifiableCredential inside the 'vp' can be further decoded to view the received credentials.
