@deploybaseline/plaid

Plaid API emulator for Baseline: Link tokens and a hosted Link page with sandbox logins, public token exchange, items, accounts and real time balances, Auth ACH numbers, transactions sync and get over deterministic sandbox data, institutions, the sandbox helpers, and webhooks signed with an ES256 Plaid-Verification JWT.

Part of Baseline: local drop-in replacement services for CI and no-network sandboxes.

Usage

npx @deploybaseline/cli start --service plaid

import { createEmulator } from "@deploybaseline/cli";

const plaid = await createEmulator({ service: "plaid" });
// Point your client at plaid.url
await plaid.close();

The official plaid Node SDK works against it once basePath points at the emulator:

import { Configuration, PlaidApi } from "plaid";

const client = new PlaidApi(
  new Configuration({
    basePath: plaid.url,
    baseOptions: {
      headers: { "PLAID-CLIENT-ID": "6650f1c0d1e2f3a4b5c6d7e8", "PLAID-SECRET": "baselinesandboxsecret000000000" },
    },
  }),
);
