Answer 1

User access token Steps

#1 Check App Key

#2 Registry User

#3 Get User Token

#4 API call

#1 Check App Key after Registry App

https://developer.ebay.com/my/keys

#2 Registry User - once if not user registry

I tested in sandbox, If you use production, needs to change production URL

https://developer.ebay.com/sandbox/register

#3 Get User Token

Sign in from developer portal

https://developer.ebay.com/

Click Sign In

Enter e-mail of user

Enter password of user

Finally Got the user access-token

#4 API call

API call with #3 user access token. In this case, user can't get the inventory due to limited scope for inventory. But I shows how to use user-token to call API.

Using Postman

Using API explorer
