Rules and Display definitions are used to define a credential. You can read more about it in How to customize your credentials.

rulesModel type

Property Type Description
attestations idTokenAttestation and/or idTokenHintAttestation and/or verifiablePresentationAttestation and/or selfIssuedAttestation defines the attestation flow(s) to be used for gathering claims to issue in the verifiable credential.
validityInterval number represents the lifespan of the credential in seconds
vc vcType verifiable credential types for this contract

The attestation type example in JSON. Notice that selfIssued is a single instance while the others are collections. For examples of how to use the attestation type, see Sample JSON rules definitions in the How-to guides.

"attestations": {
  "idTokens": [],
  "idTokenHints": [],
  "presentations": [],
  "selfIssued": {}
}

idTokenAttestation type

When you sign in the user from within Authenticator, you can use the returned ID token from the OpenID Connect compatible provider as input.

Property Type Description
mapping claimMapping (optional) rules to map input claims into output claims in the verifiable credential
configuration string (url) location of the identity provider's configuration document
clientId string client ID to use when obtaining the ID token
redirectUri string redirect uri to use when obtaining the ID token; MUST BE vcclient://openid/
scope string space delimited list of scopes to use when obtaining the ID token
required boolean (default false) indicating whether this attestation is required or not
trustedIssuers optional string (array) a list of DIDs allowed to issue the verifiable credential for this contract. This property is only used for specific scenarios where the id_token_hint can come from another issuer

idTokenHintAttestation type

This flow uses the ID Token Hint, which is provided as payload through the Request REST API. The mapping is the same as for the ID Token attestation.

Property Type Description
mapping claimMapping (optional) rules to map input claims into output claims in the verifiable credential
required boolean (default false) indicating whether this attestation is required or not. Request Service API will fail the call if required claims are not set in the createPresentationRequest payload.
trustedIssuers optional string (array) a list of DIDs allowed to issue the verifiable credential for this contract. This property is only used for specific scenarios where the id_token_hint can come from another issuer

verifiablePresentationAttestation type

When you want the user to present another verifiable credential as input for a new issued verifiable credential. The wallet allows the user to select the verifiable credential during issuance.

Property Type Description
mapping claimMapping (optional) rules to map input claims into output claims in the verifiable credential
credentialType string (optional) required credential type of the input
required boolean (default false) indicating whether this attestation is required or not
trustedIssuers string (array) a list of DIDs allowed to issue the verifiable credential for this contract. The service defaults to your issuer under the covers so no need to provide this value yourself.

selfIssuedAttestation type

When you want the user to enter information themselves. This type is also called self-attested input.

Property Type Description
mapping claimMapping (optional) rules to map input claims into output claims in the verifiable credential

claimMapping type

Property Type Description
inputClaim string the name of the claim to use from the input
outputClaim string the name of the claim in the verifiable credential
indexed boolean (default false) indicating whether the value of this claim is used for searching; only one clientMapping object is indexable for a given contract

type string (optional) type of claim

vcType type
