Create 3 API's

Creating a web app Together with Caspio Platform (non code app builder)
and entering some custom code builders.

The main focus is creating a workable Link between Amazon, 2 other warehouses.
the link is through an API that gets the specific information from each platform:

Amazon:
1. should get the daily inventory per Product each day
2. cross-check a few Shipment id from App and retrieve their status from Amazon
3. get sales per product per day

Warehouse one:
Inventory per product
Shipment Status
Drop-off Status

Warehouse 2:
Inventory per product
Drop-off Status

i will provide the API keys for the 2 warehouses
the data should be entered in a Caspio Table

the other parts of the Webbapp is already done, so the second part is transferring it into a website through Caspio Bridge and designing ita little bit so it would look nice an intuatuve
