Step 1: Get the API Key

To get the API key, contact support@igrant.io.

Step 2: Receive Verification

Copy the presentation definition received from a known verifier as per OpenID4VP. This could be obtained by out-of-band means such as email or by logging into the verifier's system. Use this endpoint to receive the verification.

Step 3: Filter Credentials

Use this endpoint to filter stored credentials against the received presentation definition.

Step 4: Send Presentation

Use this endpoint to send the selected credentials to the verifier.
