Credential Issuer Metadata

The Credential Issuer Metadata, defined by the OID4VC spec, provides detailed information about the issuer's technical and operational capabilities, supported credential types, interaction endpoints, encryption standards, and localization options for display information.

Using the waltid-issuer-api/config/credential-issuer-metadata.conf file, you can customize the supported credential types. This way you can enable the issuance of any custom credential type. Simply add another row defining your custom credential to the supportedCredentialTypes array already defined in the config file.

Please make sure to restart the issuer API service for changes to take effect.

Custom Credential Type

CustomCredential = [VerifiableCredential, CustomCredential]
  • kye The name of the credential
  • array: Type of the credential. Every W3C credential type is represented by an array, where the first type is always VerifiableCredential followed by your custom credential name.

Example Config

You can also find it in walt.id repo.
