  -H 'Authorization: Bearer {yourToken}' \

  "requestUrl": "openid4vp://authorize?client_id=did:jwk:eyJrdHkiOiJPS1AiLCJjcnYiOiJFZDI1NTE5In0&request_uri=https://verifier.example.org/request/abc123"
}'

Path Parameters

• orgID String — Organization host alias.
• target resourceIdentifier — The wallet's resource path, e.g. waltid.tenant1.wallet.

Body Parameters — Wallet2PresentCredentialRequest

• requestUrl String — The OID4VP authorization request URL from the verifier.
• keyReference (optional) String — Full resource path of the key to sign the presentation with. Defaults to the first key in the wallet's linked KMS (or the service's configured static key if the KMS has none).
• key (optional) Object — Inline serialized key ({ "type": "jwk", "jwk": { … } }). Takes precedence over keyReference.
• did (optional) String — DID to present as. Defaults to the first DID in the wallet's linked DID Store (or the configured static DID).
• runPolicies (optional) Boolean — When true, applies configured holder policies before presenting and blocks if a policy denies it. Omitted or false skips policy enforcement.

Example Response — WalletPresentResult

{
  "transmission_success": true,
  "verifier_response": {
    "status": "received",
    "message": "Presentation received and is being processed."
  }
}

• transmission_success Boolean — Whether the wallet successfully transmitted the presentation to the verifier's response endpoint.
• verifier_response Object — The raw response returned by the verifier. For a direct_post verifier (e.g. Verifier2) this is { "status": "received", "message": "…" }; some verifiers instead return a redirect_uri.
• redirect_to String (optional) — Present only when the verifier returns a redirect URL to send the user to; absent for direct_post.
• get_url / form_post_html String (optional) — Populated instead of redirect_to for the redirect (get_url) or form_post (form_post_html) response modes.

Response Codes

• 200 — Presentation built and submitted.
• 400 — The presentation request could not be resolved (e.g. an unfetchable request_uri).
  When the request resolves but no stored credential satisfies the DCQL query, the call still returns 200 with "transmission_success": false and the verifier's DCQL-fulfillment error inside verifier_response — it does not return 400.

• 401 — Invalid authentication.
