Improve logging for API errors

Problem/Motivation

currently when the API returns an http response different from 200 (201 for POST) or 302, the htt[ response body is simply logged as info message, without any additional context.

This clearly lacks context and additional information, at the very least having the response code would be helpful.

Steps to reproduce

Proposed resolution

• Add request URL, response code and other useful information.
• Perhaps use php exceptions in case of 50x errors returned from the api?
• Log 40x/50x as warning instead of notices
