The API key is created here: app.lemonsqueezy.com.

Webhook

The exact URL — including this project's id — is shown in the product after you connect. Copy it from there rather than building it by hand.

https://www.seiton.online/api/webhooks/lemonsqueezy?website_id={WEBSITE_ID}

Events worth enabling:

order_created
subscription_updated
subscription_cancelled

website_id is not optional

The signature is verified against the vault secret of that specific project. Without the query parameter the endpoint refuses the request rather than guessing which project a payload belongs to.

Worth knowing

Lemon Squeezy keys expire after roughly a year. A revoked key shows as an error on the Integrations page, not as a silent zero.

Disconnecting

Disconnect from the Integrations page. Seiton deletes the stored credentials, removes any webhook endpoint it created in your account, and strips the fields this provider owned out of your snapshots — those metrics go back to insufficient data rather than freezing at their last value.

Revoking the token or OAuth grant inside Lemon Squeezy works just as well and stops reads immediately. The connection then shows as revoked on the next sync, with the reason.
