Ebay API Workflow

Questions
1

Hey, as my first AI Agent n8n Workflow I wanted to make the Ebay descriptions of my articles a bit more useful.
I wanted an AI Agent to fill out all the important product details. Claude already coded a better template for me but to manually create every description would be too much work.

That´s why i wanted to create a n8n workflow for this. But to implement the Ebay API in a HTTP Request Node seems impossible. Are here any people who already did something else or know a solution to that problem? The main problem is the OAuth Redirect URL in the Node I think, because i can´t change that. And Ebay only gives me a RuName and no URL.

I also tried out some Community Nodes on a self hosted n8n but they didn´t work out as well.

1.95.3
n8n cloud

I would be very happy about helping ideas or fellows who already use similar Workflows.

Thanks!

I followed this tutorial here: Need access token from oauth2 Auth Code Flow to access ebay's Trade API - #5 by ricor
There was a couple of things missing though. I didn’t know where to put the n8n callback link. you put it here under the “Your auth accepted URL”.

You need to set up the credentials properely first and log in using OAuth. http request node is just the matter of using right endpoints and setting up correct headers and other parameters - which can be tested on the API Explorer (Sign in or Register | eBay Developers Program)

I even managed to connect it to MCP server and use this server within claude code so it’s definitely doable
