Overview

Requests a live DoorDash Drive delivery-fee quote for an order — the storefront-facing half of this extension (called from Spree::Calculator::Shipping::DoordashQuote during checkout, M3) and again at order.completed if the original quote expired (M4).

order.total at whichever moment this is called is what's sent as order_value — Spree recalculates on every checkout step already, and DoorDash isn't in the money path (Spree's own payment method still charges the customer; DoorDash only uses this for delivery-fee/ insurance math).

  # 409 duplicate_delivery_id, even though the first quote is still open
  # (not yet accepted or expired). Checkout recalculates shipping rates
  # on essentially every step, so calling this twice for the same order
  # is the normal case, not an edge case — a stable per-order id made
  # the DoorDash rate silently vanish (RequestError is rescued below,
  # same as any other unserviceable-rate case) after the very first
