  }
}

401: Unauthorized Invalid Signature or API_KEY

403: Forbidden Privacy Consent Not Allowed

400: Bad Request Invalid Request Payload

This endpoint will return an auth token and an access token. Your dApp needs to combine them into one encoded string, delimited by a : and base64 encoded, in order to use it as an X-Access-Token header to fetch PII data.

Privacy Access Tokens are one time use tokens. If you attempt to reuse an access token, you will receive a 401 Unauthorized error.

NodeJS

const buffer = require('buffer');

const privateKeyDer = '...';
// You can find `getPrivateKeyFromDer` in "How to sign API"."Full Example" page
const privateKey = await getPrivateKeyFromDer(privateKeyDer);

const walletAddress = '...';

// You can find `makeRequest` in "How to sign API"."Full Example" page
const json = await makeRequest({
    method: 'get',
    privateKey: privateKey,
    path: `/api/v1/privacy/access/${walletAddress}`
});
const { data: { authToken, accessToken } } = json;

const xAccessToken = Buffer
    .from(`${authToken}:${accessToken}`)
    .toString('base64');
