Overview
Plaid connects to user bank accounts and exposes transaction data — key-based (a GET to a POST route returns a structured 404, verified).
Quick Start
Requires client_id + secret + access_token (POST):
curl -X POST "https://sandbox.plaid.com/transactions/sync" \
-H "Content-Type: application/json" \
-d '{"client_id":"YOUR_ID","secret":"YOUR_SECRET","access_token":"YOUR_TOKEN"}'{ "error_code": "NOT_FOUND", "error_message": "invalid route: /transactions/get" }Authentication
- Register at plaid.com → client_id + secret (sandbox keys free).
- POST JSON with client_id/secret (wrong route → structured 404, verified).
Rate Limits & Notes
- Sandbox free; production is paid per Plaid’s pricing.
- Transactions, balances, identity, auth.
FAQ
Is Plaid free? Sandbox free; production paid.
Why 404? The route was wrong for the method (verified) — use the docs’ POST routes.
What’s the auth style? client_id + secret in JSON body.
