It's probably best to follow exactly one document, to avoid any confusion
from mixing things.
I think that you are following the second one here with its method number
2, using the stock nginx proxy_cache_bypass directive.

Your configuration for https://gsmanginxproxycachepurge.testapicraft.com
reads the $bypass variable if it is set; but it never sets it, so it will
be read as "empty", and the proxy_cache_bypass directive will *not*
cause the cache to be bypassed in this case.
If you want to use this method, you must ensure that your $bypass variable
is set for the one request that you are making.
Good luck with it,
