I created and prepared eBay API (another freelancer here did that)
It was fronted with.
However, Fronted wasn't done.
Here's what you'll need to check and do the rest of the work.
A REST API was created, but I don't know Password anymore.
Example [login to view URL] (opens login)
eBay API interface connection.
You have to prepare the connection for eBay interface.
Each interface must be explained in detail.
I will integrate this interface with Fronted.
The eBay interface must be detailed.
Example of how the product is exported, imported, scheduling, message API, opening and closing cases.
so many other functions.
The interface must be understandable for other programmers.
Otherwise he can't do Fronted.
I have a developer eBay account and API section was made there.
But you must check how far it is.
