Definition
A webhook is an outbound callback: instead of you polling, Credicorp POSTs a signed event to your registered endpoint when something changes. Delivery is at-least-once, so duplicates are normal, and each carries a signature you must verify.
In plain terms
A push notification from the API to your server when an event occurs.
Why it matters here
Verify the signature, respond 2xx fast, and process idempotently. See webhooks and event delivery.
