[Feature request] Events/hook to other service

[anciaux]

Following the suggestion of M. Tournoy, I post here a request feature:

I would like to trigger events when a paper changes state, so that other services/servers/hooks could perform user defined actions.

For instance when a paper becomes tagged of the copy-editing stage, we usually create a directory within a gitlab repository. We store the latex sources and open review, ready to do some checks and also to perform finalization.
These simple operations could be scripted, and therefore could relieve the editors from these click-button tasks.

M. Tournoy suggested to have:

• an event containing the paper information sent to a user defined external server
• a documented version of the API, allowing the external server to retrieve all the information regarding the paper.

If that is somehow already possible, or if I could help somehow to put this in place, that would be very much appreciated.
