deploy preproduction API

[Haransis]

Is your feature request related to a problem? Please describe.
Testing GET and POST locally is quite tedious.

Describe the solution you'd like
Deploy a preproduction API to send testing data to.

Describe alternatives you've considered
A mock server could also be used to serve this purpose.
However I think testing should be done without the use of a mock server, when releasing a new version.
