I’m unable to complete OAuth2 authentication with eBay’s Sandbox environment in N8N. After following all documented steps, the OAuth flow fails at the redirect stage with “we looked everywhere. looks like this page is missing.”
Deployment is self-hosted
Target Endpoint: Inventory API (/sell/inventory/v1/inventory_item)
The goal is to get Ebay store listing information to google sheets
Please give a step by step on how to get this connected. Thanks in advance
