You didn't mention in the post, but you tagged the question with [Dukt oAuth](https://dukt.net/oauth).

If you're trying to connect with that, Channel Advisor isn't a 1st or 3rd party Dukt oAuth provider. You can see a list of the available ones here: <https://dukt.net/oauth/providers>

You'd need to right an oAuth Channel Advisor [Craft plugin](https://craftcms.com/docs/plugins) in order for it to work.
