# W3C Credentials

A `W3CCredential` is a member of the `Credential` union type, representing a credential which follows the W3C Verifiable Credentials Data Model 1.1 specification. W3C credentials can be managed using the same queries and mutations as for any credential.

## View W3C credentials

View held W3C credentials, with pagination and filtering options. Returns a `nextToken` which can be passed into the same query in order to fetch subsequent pages.

```graphql
query MyQuery {
  credentials(
    page: {
      nextToken: null
    }
    filter: {
      credentialFormats: [W3C]
    }
  ) {
    items {
      __typename
      ... on W3CCredential {
        id
        credentialJson
      }
    }
    nextToken
  }
}
```

Alternatively, view a single W3C credential, referenced by its unique ID.

```graphql
query MyQuery {
  credential(
    credentialId: "19d8917d9fd44d09b93eb5a1a71282dd"
  ) {
    __typename
    ... on W3CCredential {
      id
      credentialJson
    }
  }
}
```

## Delete a W3C credential

Delete a held W3C credential.

```graphql
mutation MyMutation {
  deleteCredential(
    credentialId: "19d8917d9fd44d09b93eb5a1a71282dd"
  )
}
```
