How to validate user and password oelo webView.

Dear,
I know it's not mandatory but could you guide me? able to see the generation of the firebase token but I could not understand how you pass this parameter to the backend, it is already necessary to check which user is linked to it. would it be through the header in the webView in the native App? Thanks in advance.

You have to save it in the user attributes. Check the official app.

Hi Anton,
I think I didn't express myself correctly. I know that it is saved inside the attributes object of the user, I would like to understand how you check in the App manager to be able to insert it in the correct user. Excuse my ignorance but I'm still not on a level like yours. I couldn't see the call to the API checking the username and password. Sorry if I'm not being clear. Thanks for always helping.

Traccar Manager calls a special method that the web app defines:

Thanks Anton,
I promise I will study and understand how it works. I will analyze App manager and also web app. thanks.
