Definition
At-least-once is the delivery guarantee for Credicorp webhooks: retries mean an event may be delivered more than once and occasionally out of order, but it will not be silently dropped. The trade is that consumers must handle duplicates.
In plain terms
Every event definitely arrives, but you might get it more than once.
Why it matters here
De-duplicate on the event ID and order by state, not arrival. See building an idempotent consumer.
