To buy your Amazon Prime shipping labels on Amazon you must initially take the following actions in your Seller Central

Accept delivery methods
Enable "Shipped by Seller" API access

Then, you can perform the following actions via the Lengow orders API.

Step 1: Call the available delivery methods on an order via the action set_eligible_shipping_methods" when your Prime order is awaiting shipment.
Step 2: Save the settings "shipping_service_offer_id" and " shipping_service_id " on the delivery label you want to buy.

Note: If you already know the parameters "shipping_service_offer_id" and "shipping_service_id" of the label you want to buy, it is not necessary to make this call.

Step 3: Buy the delivery label. Call the "buy_shipment_label" corresponding to the delivery method selected in the previous step.

This call will return the delivery label in the "documents" parameter of the Lengow Orders API as a URL.

There is no need to do the "ship" action because the order will automatically be set as "shipped" by Amazon following the buy_shipment_label action.

Contact our Support team for more details on the overall purchase of delivery labels procedure. We also advise you to read the Lengow technical documentation on the subject.
