        UserAuthResponse? userAuthResponse = System.Text.Json.JsonSerializer.Deserialize(MyUserData);
        string UserID = userAuthResponse.Data.UserID;

In order to retain values between GET and POST requests in Razor Pages, you can make use of hidden fields or session variables.
Use a hidden field in your Razor Page to store the value of userAuthResponse.Data.UserID.

In your POST method, you can retrieve the value of UserID from the form data:

public async Task OnPost(UC.ADC.Core.Entities.SQL.Branch branch)
{
    string userID = Request.Form["UserID"];
}

Alternatively, you can also use session variables to store the value of UserID between requests.

public void OnGet()
{
    string MyUserData = Request.Cookies["myUserData"];
    UserAuthResponse? userAuthResponse = System.Text.Json.JsonSerializer.Deserialize(MyUserData);
    string UserID = userAuthResponse.Data.UserID;

    HttpContext.Session.SetString("UserID", UserID);
}

public async Task OnPost(UC.ADC.Core.Entities.SQL.Branch branch)
{
    string userID = HttpContext.Session.GetString("UserID");
}

public async Task OnPost(UC.ADC.Core.Entities.SQL.Branch branch, string UserID)
{
    // Access the UserID value here
    // ...
}
