order.paid, subscription.created, or checkout.updated events?Polar follows the Standard Webhooks spec. Each request
carries three headers — webhook-id, webhook-timestamp, and webhook-signature — and the
signature is an HMAC-SHA256, base64-encoded, over {webhook-id}.{webhook-timestamp}.{body}.
Always verify against the raw request body — don't JSON.parse first.
Use Polar's official SDK helpers, which parse and verify in one call:
Node (@polar-sh/sdk):
const { validateEvent, WebhookVerificationError } = require('@polar-sh/sdk/webhooks');
try {
// rawBody: Buffer/string of the raw HTTP body; headers: the request headers object
const event = validateEvent(rawBody, headers, process.env.POLAR_WEBHOOK_SECRET);
// event.type -> e.g. "order.paid"; event.data -> the resource
} catch (err) {
if (err instanceof WebhookVerificationError) {
// invalid signature -> respond 400/403
}
}
Python (polar-sdk):
from polar_sdk.webhooks import validate_event, WebhookVerificationError
try:
event = validate_event(body=raw_body, headers=request.headers,
secret=os.environ["POLAR_WEBHOOK_SECRET"])
except WebhookVerificationError:
... # invalid signature -> respond 400/403
Secret gotcha: The Standard Webhooks spec expects the secret to be base64-encoded before signing. The Polar SDKs base64-encode your dashboard secret for you, so pass the secret as-is. For a manual verifier, base64-encode the secret first (see references/verification.md). Polar secrets are user-set or randomly generated — they are not
whsec_-prefixed.
For complete handlers with route wiring, event dispatch, and tests, see:
| Event | Triggered When |
|---|---|
checkout.updated | A checkout session changes state (e.g. confirmed) |
order.created | A new order is created (purchase or subscription renewal) |
order.paid | An order is fully paid |
order.refunded | An order is refunded |
subscription.created | A new subscription is created |
subscription.canceled | A subscription is set to cancel at period end |
subscription.revoked | A subscription ends and access should be revoked |
customer.state_changed | A customer's state changes (subscriptions/benefits) |
For the full list of 30+ events, see Polar Webhook Events.
POLAR_WEBHOOK_SECRET=your_webhook_signing_secret # From the endpoint settings in Polar
# Start a tunnel to your local handler (no account needed)
npx hookdeck-cli listen 3000 polar --path /webhooks/polar
Polar also ships a first-party tunnel: polar listen http://localhost:3000/, and a sandbox
environment (sandbox.polar.sh) for test purchases without real charges.
