}

SDK Usage

import { BKeyClient } from '@bkey/sdk';

const bkey = new BKeyClient({
  clientId: process.env.BKEY_CLIENT_ID!,
  clientSecret: process.env.BKEY_CLIENT_SECRET!,
});

// Token is automatically obtained and refreshed

from bkey import BKeyClient

client = BKeyClient(
    client_id="your-client-id",
