How to link API key to user

[ErikDB87]

I'm setting up Reitti, and I think I've completed the flow to transfer location data from openHAB to Reitti. (I've made an openHAB rule that sends a HTTP POST request with JSON payload. In that payload, there's either API key A, if the location comes from my phone, or API key B, if the location comes from my girlfriend's phone. I've also made two users in Reitti (obviously one for me, and one for her).

But I can't figure out how to link API A to "my" user, and API B to her. And without doing that, I assume Reitti treats all location updates as for the same person.

Thanks in advance for any help!

And seconds later I had an idea... Instead of creating the API keys as the administrator, why not try creating one as each respective user. ;)
