1.) Do you already have a tutorial on the blocking/non-blocking topic?
2.) How can I log the response body for debugging for failing requests?

Thanks Dan. What if the header to be passed on every request is not static, such as a bearer token that has to be replaced when it expires? I wonder if you might have covered that in one your spring security videos?

Hello! Well http interfaces is a cool substitution for feign client. But migrating from feign on my production project I have tackled with an issue that http interface does not support fallbacks out of the box. But feign does. What is more appropriate way to implement fallback just like on feign. We want to make a decorator arond the client. Do you have any better solution?
