Create and manage RMA (Return Merchandise Authorization) labels and track return shipment status via EasyPost

Steps

1. Create a return shipment via POST /shipments with is_return set to true; swap the to_address and from_address compared to the original outbound shipment so the label routes back to your warehouse
2. Purchase the return label using the desired carrier and service; retrieve the label_url for PNG or PDF format and the tracking_number
3. Send the label URL or a QR code representation to the customer via email; for boxless returns, use the EasyPost QR code label feature if the carrier supports it
4. Associate the return tracking number with the original order in your OMS using EasyPost's Tracker API; create a Tracker object if one is not automatically created at label purchase
5. Subscribe to tracker.updated webhook events filtered to the return tracking number to receive real-time status updates (in transit, out for delivery back to warehouse, delivered)
6. Trigger receiving workflows in your WMS when the tracker status transitions to delivered so the returned item can be inspected and dispositioned
