Amazon MWS, Product Update (Shipping Group, Min/Max Price)

***** NOTE This requirement is for a developer with great Amazon API skills and with your *OWN* Developer credentials. If you cannot demonstrate or provide evidence that you are able to bring these two CORE requirements and you respond with 'Copy and Paste responses about the WooCommerce websites you have developed then you will have little to no chance of this project being awarded. Thank you for your understanding ***** I have a basic requirement to make changes to products on my Amazon account.  The changes are against a SKU for 3 fields (initially) and subscribed Maketplaces (UK,DE,FR,IT,ES). More Specifically Partial Updates for ; 1) Merchant Shipping Group 2) Minimum Price 3) Maximum Price Data is supplied in a formed json file which is located on the same server.  A vhost has been commissioned blank for the project already and you are expected to have your own Amazon developer credentials for the project (which of course will be authorised to access our account). This is a test project to find a freelancer to work with on an expansion of this project. If you have worked with Linnworks and their API that would also be great as the next project will be to update Amazon with dates for expected delivery of more stock, querying Open Purchase Orders in Linnworks to obtain detail of stock that is due and average lead times, etc. Thanks for looking in Stuart
