Verify Credential

Verify a W3C Verifiable Credential using cheqd Studio.

Last updated 7 days ago

Was this helpful?

Once you have issued your credential and have a JWT as part of the credential proof, you can use the /credential/verify API to check that the JWT has not been tampered.

Step 1: Obtain Credential to Verify

To verify a Credential, you can either pass the full Credential body or the JWT proof. These can be either obtained from a or from a Verifiable Presentation presented to the user.

Step 2: Configure Verification Parameters

The user is able to set verification parameters to filter whether they want to verify certain aspects of a Credential, including:

verifyStatus
  • true (indicates that the user wants to verify the Credential Status, requiring a credentialStatus property to be present in the Credential)

  • false (Default. Indicates that the user does not want to verify the Credential Status.

fetchRemoteContexts

When dealing with JSON-LD type Verifiable Credentials you also MUST provide the proper contexts within a Credential body. Set this to true ONLY if you want the @context URLs to be fetched in case they are a custom context.

  • true

  • false (default)

Step 3: Pass the Credential to the API

Simply paste the JWT or the full credential body into the request field of the /credential/verify API, and the API will give you a response including the following verification policies:

  1. Whether the Credential has been tampered

  2. Whether the Credential has a valid issuance date

  3. Whether the Credential has expired

  4. Whether the Credential Status is valid
