Request presentations over DIDComm

For wallets on the DIDComm rail, presentations run over Present Proof 2.0. You ask for specific attributes of a credential definition (AnonCreds) or of a schema credential (JSON-LD); the holder reveals only those.

Prerequisites​

  • An active Verifier accreditation for the schema, with the agent as VS operator.

Steps​

curl -s -X POST http://127.0.0.1:3000/v2/didcomm/presentation-request -H 'content-type: application/json' -d '{
  "requestedCredentials": [ { "credentialDefinitionId": "<credDefId>", "attributes": ["memberName","memberId"] } ],
  "requireNonRevocation": true,
  "autoAccept": true,
  "didcommVersion": "v2"
}' | jq '{proofExchangeId, shortUrl}'

Without a connection the agent returns an invitation and a short URL for a QR code; with connectionId it requests on the existing connection. For a JSON-LD credential, name the jsonSchemaCredentialId instead of a credential definition.

curl -s http://127.0.0.1:3000/v2/didcomm/presentations/<proofExchangeId> | jq '{state, verified, claims: .revealedAttributes, trust}'

The agent verifies the proof, then runs the trust decision on the issuer of each credential presented: the issuer must be a trusted Verifiable Service holding an active issuer accreditation for the schema now. With autoAccept off, accept the presentation on the didcomm.presentations.state-updated event.

Verify​

Request a credential issued by the playground's accredited demo issuer from Hologram Messaging on testnet: verified is true and the trust verdict is TRUSTED_AUTHORIZED.
