Server doesn't update tracker id automatically

Hello,

when I insert a new device with its id into the database the server doesn't write the positiondata into it. Only after restart of the traccar server all works fine. Could anyone give me a hint what I can do?
In the log files I see this error messages:

Traccar for iOS (unclear for me what this means)

You need to use API instead of changing database directly. As for Traccar Client issue, it looks like you are using HTTPS instead of HTTP.

Thanks for your support. I understood that I can't insert devices diretly to my db. That's what I'm currently doing.
I'm a rookie to api technologies and I don't know how to use it. Do you know a page where I can find more detailed information and help how to implement it and doing the http calls?

It's a pretty standard REST API. There is plenty of information online. You can also just check what official web app sends.

One more, hopefully not a stupid question. Which username and password must be used for the REST call? E-Mail address and password of a user with admin permission?

Any user that has access to the data that you want to change.
