Its a good idea to also allow configuring global options on the component level so you DRY on each endpoint. This can often by login parameters, url to servers etc. And in this case the url/token/etc to the 3scale admin portal.
You can then also have these settings on the endpoint level, so its 2-tiered, and you can then configure on either level, or mix them. and let endpoint override component level.
Also a bonus is that component level options can easily be configured in spring boot auto configuration.
