Lithic Webhooks

Lithic delivers events (card issuing, transactions, disputes, money movement) to your endpoint as webhooks. They implement the Standard Webhooks spec (powered by Svix), so verification is HMAC-SHA256 over {webhook-id}.{webhook-timestamp}.{rawBody} with a per-subscription signing secret.
