Issue Credentials via CLI

Issuing Credentials via CLI​

Once the Issuer Node installation is completed, the following will walk you through issuing credentials via a CLI.

note

These steps can be done either via the API UI (http://localhost:3001) or directly in the UI (http://localhost:8088).

Create Identity​

note

This is an alternative to the following: Create Issuer ID.

# NOTE: dXNlci1pc3N1ZXI6cGFzc3dvcmQtaXNzdWVy is a Basic HTTP Authorization as base64(user-issuer:password-issuer) from our .env-issuer file
curl --location 'http://localhost:3001/v1/identities' \
--header 'Authorization: Basic dXNlci1pc3N1ZXI6cGFzc3dvcmQtaXNzdWVy' \
--header 'Content-Type: application/json' \
--data '{
    "didMetadata":{
        "method": "polygonid",
        "blockchain":"polygon",
        "network": "amoy"
    }
}';

# Expected Output:
#   {"identifier":"did:polygonid:polygon:amoy:2qPdb2hNczpXhkTDXfrNmmt9fGMzfDHewUnqGLahYE","state":{"claimsTreeRoot":"eb3d346d16f849b3cc2be69bfc58091dfaf6d90574be26bb40222aea67e08505","createdAt":"2023-03-22T22:49:02.782896Z","modifiedAt":"2023-03-22T22:49:02.782896Z","state":"b25cf54e7e648a263658416194c41ef6ae2dec101c50dfb2febc5e96eaa87110","status":"confirmed"}}

(Optional) View Existing DIDs (connections)​

A connection is a DID that is linked to the issuer when they authenticate via an issued credential.

note

You can check all the connections on the Issue Node UI.

Using a CLI​

This will output all DIDs (i.e. connections) that have been created with the issuer.

curl --location --request GET 'http://localhost:3001/v1/identities' \
--header 'Authorization: Basic dXNlci1pc3N1ZXI6cGFzc3dvcmQtaXNzdWVy' \
--header 'Content-Type: application/json' \
--data '{
    "did_metadata":{
        "method": "polygonid",
        "blockchain":"polygon",
        "network": "amoy"
    }
}';

# Expected Output (Results may vary based on number of DIDs created):
#   ["did:polygonid:polygon:amoy:2qMd3PtcVbzDNQZBiSDctaigbQtYW9KTqrLFoUm4Ur","did:polygonid:polygon:amoy:2qMeNWv9xSSvWyBpn5tDojzQ8sga4VtrfuAkV65zQa","did:polygonid:polygon:amoy:2qPdb2hNczpXhkTDXfrNmmt9fGMzfDHewUnqGLahYE","did:polygonid:polygon:amoy:2qLR2qA22RemPeQDsQwdrrMU3SM9CNLnRBhmQtzo5v","did:polygonid:polygon:amoy:2qHYtws8GQN3RniHLjPf5GuZUZtcD37o1MUgUmw287"]

Creating Credentials​

This will go through creating a KYCAgeCredential credential based on the following KYC Age Credential Schema.

note

Learn how to create credentials on the Issuer Node guide.

Using a CLI​

Before creating a credential, the identifier of the service/person is needed. To retrieve this, the identifier can be copied from the Polygon ID app to the clipboard.

"ID Within Polygon ID App"

note

The issuer node DID can be retrieved by looking at .env-api for ISSUER_API_UI_ISSUER_DID

curl --location 'http://localhost:3001/v1/did:polygonid:polygon:amoy:2qPdb2hNczpXhkTDXfrNmmt9fGMzfDHewUnqGLahYE/claims' \
--header 'Authorization: Basic dXNlci1pc3N1ZXI6cGFzc3dvcmQtaXNzdWVy' \
--header 'Content-Type: application/json' \
--data '{
    "credentialSchema":"https://raw.githubusercontent.com/iden3/claim-schema-vocab/main/schemas/json/KYCAgeCredential-v3.json",
    "type": "KYCAgeCredential",
    "credentialSubject": {
        "id": "did:polygonid:polygon:amoy:2qEsg1AeTohAq6Euc3hBaDapfLVfQiWS7DUfvutYEq",
        "birthday": 19960424,
        "documentType": 2
    }
}';

# Expected Output:
#   {"id":"b1eab5be-dea3-11ed-8f7d-0242ac1e0005"}

(Optional) Verifying Credentials Creation​

note

You can always check the created credentials on the Issuer Node UI.

Using a CLI​

Using the previously generated credential ID from Creating Credentials.

curl --location --request GET 'http://localhost:3001/v1/did:polygonid:polygon:amoy:2qPdb2hNczpXhkTDXfrNmmt9fGMzfDHewUnqGLahYE/claims/b1eab5be-dea3-11ed-8f7d-0242ac1e0005' \
--header 'Authorization: Basic dXNlci1pc3N1ZXI6cGFzc3dvcmQtaXNzdWVy';

Issuing Credential To Polygon ID Wallet User​

This will walk you through the steps of issuing a credential to the Polygon ID wallet app.

note

To learn how to issue credentials to a Polygon ID Wallet User, please refer to the Issuer Node Guide.

Using a CLI​

In order to get the credential on the Polygon ID App, the credential QR Code payload is needed.

curl --location 'http://localhost:3001/v1/did:polygonid:polygon:amoy:2qPdb2hNczpXhkTDXfrNmmt9fGMzfDHewUnqGLahYE/claims/b1eab5be-dea3-11ed-8f7d-0242ac1e0005/qrcode' \
--header 'Authorization: Basic dXNlci1pc3N1ZXI6cGFzc3dvcmQtaXNzdWVy';

# Expected Output:
#   {"body":{"credentials":[{"description":"https://raw.githubusercontent.com/iden3/claim-schema-vocab/main/schemas/json-ld/kyc-v3.json-ld#KYCAgeCredential","id":"b1eab5be-dea3-11ed-8f7d-0242ac1e0005"}],"url":"http://localhost:3001/v1/agent"},"from":"did:polygonid:polygon:amoy:2qPdb2hNczpXhkTDXfrNmmt9fGMzfDHewUnqGLahYE","id":"c01b66f1-d10b-4591-9dd6-8a94db1c112a","thid":"c01b66f1-d10b-4591-9dd6-8a94db1c112a","to":"did:polygonid:polygon:amoy:2qEsg1AeTohAq6Euc3hBaDapfLVfQiWS7DUfvutYEq","typ":"application/iden3comm-plain-json","type":"https://iden3-communication.io/credentials/1.0/offer"}

Take this JSON data, copy, and paste into https://qr.io.
