# Record that the recipient opened a Slack notification link

`POST /offer_deliveries/{uuid}/open`

Slack notification "Open in Rhythms" links carry from_notification=<offer delivery uuid>. The web app calls this once when such a page loads. Stamps opened_at (and delivered_at) on the recipient's offer delivery; later calls are no-ops. Only the notification's recipient may call it. This is the ignore signal for the offer.
