Sure you can do it via the API:

[https://developer.mautic.org/#create-contact](https://developer.mautic.org/#create-contact)

I wrote it a bit more in detail in this thread: [Update the segment and create a contact from the script - #3 by dirk\_s](https://forum.mautic.org/t/update-the-segment-and-create-a-contact-from-the-script/31491/3)

But if you use a mobile App - is there a server side part as well? I ask, because otherwise you would need to include the API key in the mobile App, which may not be the best idea in regards to security.
