Create PHP / MYSQL Jet.com integration

General information for the business: Add / Update products and update their quantity
Description of requirements/functionality: We require an integration to be built for JET.COM - this needs to be done in PHP / MYSQL.

Part 1:
Product information will be stored in the MYSQL Database and these records need to be pushed to JET.COm by using their API.
The developer needs to built the Jet.com Database in MYSQL and create a table with all fields available according to their API documentation.

It needs to be possible to push each record separately as we will be populating this table ourselves over time. (do not use file upload, but rather the Products API)

PUT:
SKU Upload
Image Upload
Price Upload
Inventory Upload
Variation Upload
Shipping Exception Upload
Returns Exception
Archive SKU

Part 2:
From another table where we store only SKU / QTY (table name, productqty), we need to be able to bulk push all new QTY's for SKU's in that table to JET.COM and update all products with the new qty's. Use the File Upload API only for this operation.

Part 3:
Download in bulk all data for verification purposes - which items are listed and the state that they are in. See API for more informaiton: https://developer.jet.com/docs/overview
