Overview

Receives Uber Direct webhook notifications. HMAC-verified (see SpreeUberDirect::WebhookVerifier) rather than DoorDash's Basic-Auth string-echo. Does the least possible work synchronously: verify, record, ack, hand off to a job — same shape as every sibling WebhooksController in this codebase.

  # Uber's dashboard lets a webhook subscribe to three event kinds on
  # this one endpoint: `event.delivery_status` (the only one with a
  # `status` field — confirmed live), `event.courier_update` (a
  # courier GPS ping fired every 20s once a courier is assigned — no
  # `status` field, confirmed live), and `event.refund_request` (fired
  # when a refund is requested — no `status` field either, confirmed
  # directly against Uber's own webhook payload docs). Unlike a
  # courier ping, a refund notification carries real, unrecoverable
  # data (data.id, currency_code, total_partner_refund,
  # total_uber_refund, refund_fees, refund_order_items) — worth a
  # durable record even with no consumer yet, so it's persisted to its
  # own RefundEvent table before falling into the generic
  # blank-status drop below.

  # WebhookEvent's `status` column is specifically Uber's *delivery*
  # status (see its own model comment) and requires presence, so
  # acknowledge and drop anything else that doesn't carry one rather
  # than letting it fail validation and surface as a 404 to Uber's
  # webhook delivery system — a courier-location ping needs no
  # processing from this extension today.
