Hi @Jujusticier, webhook.site is a great starting point for inspecting your requests and would also show the token attached by n8n when using OAuth2-authenticated requests.
n8n’s logging itself is unfortunately somewhat limited, especially around OAuth2, so I am not aware of other ways to increase visibility here I am afraid (beyond simply throwing additional logging statements in the code and thus building a custom version of n8n).
When you mention webhook.site doesn’t get the HTTP Requests you are making, are you sure you are using the right URL? These requests would have to go to your personal and unique URL:
Ok I found the solution. If you are trying to connect to Qonto API : go look for the community node here Qonto node (especially if you are working in the sandbox) or put the authentication in Body not Header Issue with qonto.com and OAuth2 callback
Now I am going to try to contribute to this node !! thank you for everything @MutedJam
