Notes

  • Current step, not every scan: SwiftX's tracker shows the full scan list only to someone who enters the last 4 digits of the recipient's phone number. Without them it gives the parcel's step on a five-step bar (Label created, Picked up, In transit, Out for delivery, Delivered) and when that step was last updated. lastscanned returns that step as one event (code is step 1 to step 5) and says so in message.
  • Statuses: Label created maps to label_created; Picked up and In transit to in_transit; Out for delivery to out_for_delivery; Delivered to delivered.
  • Time zone: SwiftX gives the update time with no zone, so only localTime is set and timestamp is null.
  • Bot wall: swiftx-express.com puts its tracker behind a Cloudflare challenge, so lookups run in a cloud browser and take about 10 to 15 seconds. A batch of up to 20 numbers shares one browser session.
