Open a presentation request DIDComm message​


import { isPresentationRequestJwm } from "wallet-sdk-react-native";
const openResult = await wallet.did.messaging.openDidCommMessage(message);

if (openResult.isErr() || !isPresentationRequestJwm(openResult.value)) {
    return;
}

const presentationRequest = openResult.value;

const credentialData = [
    { id: "a", credential: credentialA },
    { id: "b", credential: credentialB },
];

const filterResult = await wallet.credential.webSemantic.filterCredentialsByQuery({ credentials: credentialData });

Create and send presentation​


const createPresentationResult = await wallet.credential.webSemantic.createPresentation({
    challenge: presentationRequest.body.challenge,
    domain: presentationRequest.body.domain,
    credentials,
    holder: did,
});


if (createPresentationResult.isErr()) {
    // Handle error from createPresentationResult.error 
    return;
}

const presentaiton = createPresentationResult.value;

const sendPresentationResult = await wallet.credential.webSemantic.sendPresentationResponse({
    presentationRequest,
    presentation,
});
