Test Plaid webhooks
Plaid sends webhooks for transactions updates, item status changes, and auth events, verified with signed JWTs. Capture them on a free webhooks.cc endpoint to see exactly what Plaid sends — or fire realistic sample payloads at your own handler without touching a production account.

How to test Plaid webhooks
- 1
Create a webhook endpoint
Sign in free with GitHub or Google to create a persistent endpoint — or grab an instant guest URL at webhooks.cc/go without an account.
- 2
Point Plaid at your URL
Paste the endpoint URL into Plaid: Set the webhook URL when creating a Link token (or via /item/webhook/update).
- 3
Inspect what arrives
Each delivery appears live in the dashboard with method, headers, body, query parameters, and source IP.
- 4
Forward to localhost or assert in CI
Run whk tunnel <port> to forward webhooks to a local server, or use the TypeScript SDK to wait for and assert on deliveries in tests.
