TIMEBOX

[DONE] Use the 5-story point equivalent effort time to estimate whether the points below are achievable, extract the follow-up issues if needed
[IMPLEMENTATION] estimates much higher and was done in the scope of this ticket.

Base AC

• make sure that delivery endpoints dynamically alter their behaviour based on the state of the configuration env selected (implementation-wise)
• how does one communicate a desired configuration env from e.g. an http client request (e.g. i want to test my endpoint against several configurations, how do i communicate which config env to use with a request - over a request header? query param? cookie? ..)
