How to interface to Ebay ecommerce system?

[amorosik]

How can I automatically communicate with an Access-based management system and e-commerce systems, such as eBay, from a seller's perspective?

By 'communicate,' I mean:
- create sales listings
- receive purchase order notifications
- manage tracking messages for shipped items

Depends on whether or not the site provides api’s to allow you to do what you actually want.

Each will be different, some are provided free, others you pay for a license

eBay API - PublicAPI

eBay API provides Sell and Buy on eBay

Search sitename api for others
Search ‘rest api in vba’ for how to implement in access

As usual, your phrase ‘automatically communicate’ is vague. Automation will typically be from the access end to poll the site. So far as I am aware it is not possible for the site to automatically send reports, although you could get email
notifications of sales and other transaction events - use outlook automation or rules to process these

Edit - some sites regularly change the nature of what you download- content, name and location so be prepared to be fully involved with updating your processes to manage this - you should receive notifications from the site (or visit regularly) to keep abreast of any changes
