Wrap or Build my own mobile application for the client

Hi,

First of all I would like to thank all of you for your hard efforts!

I was wondering if I can build my own client app or wrap the current existing one with new framework. I want to either wrap the app with flutter or react native technologies or to build a simple client app in which I can send details to my deployed server.
I looked at the API documentation and it was well explained, but I could not understand it from client side and how to manage client app features to update location, post id and post server url.
If there is a way in which I can wrap the current app easily or get the minimum required API to use then this would be great.

Thanks!!

Traccar Client uses this format to upload the data:

I tried it using my deployed server and it is giving me 404 Not found error.

That probably means you haven't registered the device.

In fact I have the device registered and I have even changed the id to meet the device id registered in the server.

And are you using the correct port (5055)?

Just tried it and I got the same status 404 Not found.

What do you see in the server logs?

Thank you sir!
Really appreciate your effort, I have fixed the error.
Regards.

I see this:

GET / HTTP/1.1

Where the data? Where's the id?
