If someone asks for specific ways we use the MWS, it's okay to tell them which sections we use. We can't share how we use them or how we manage throttling. I asked Jon when a user asked just to be sure what we can/can't share:
We use the Product, Orders, Finance, Fulfillment Inbound Shipment. The throttling limits are referenced in the AWS documentation. The management of throttling issues depends upon how each software product handles it (ours does this extremely well) and which API's are being used.
Throttling: https://docs.developer.amazonservices.com/en_US/dev_guide/DG_Throttling.html
MWS documentation: https://developer.amazonservices.com/gp/mws/index.html/147-1532506-2206608
I wouldn't want to give away the way we use them and how we manage the throttling.
