I have downloaded the WordPressPCL example project in https://github.com/wp-net/WordPressPCL.
What I need is to update a page or post of WordPress but I don’t find any example.
All I find are examples of how to get one or many pages or posts, or how to create a new page.

But how to update the date or title of a page?
In my attempts I receive BadRequest or NotFound responses.

I can get pages without problem doing this:

    public async Task<DataTable> LoadPagessAsync()
    {
        var client = new RestClient("https://myfoowebname.com/wp-json/wp/v2/"); //obviously this url is fake

        DataTable table = new DataTable();
        table.Columns.Add("ID", typeof(int));
        table.Columns.Add("Title", typeof(string));
        table.Columns.Add("Date", typeof(DateTime));

        int page = 1;
        bool morePages = true;

        while (morePages)
        {
            var request = new RestRequest($"pages?Authorization=Bearer{Web.Authorization}", Method.Get);
            request.AddParameter("per_page", 100);
            request.AddParameter("page", page);

            var response = await client.ExecuteAsync(request, Method.Get);

            if (response.IsSuccessful)
            {
                var pages = JArray.Parse(response.Content);
                foreach (var pageItem in pages)
                {
                    table.Rows.Add(pageItem["id"].Value<int>(), pageItem["title"]["rendered"].Value<string>(), pageItem["date"].Value<DateTime>());
                }

                if (pages.Count < 100)
                {
                    morePages = false;
                }
                else
                {
                    page++;
                }
            }
            else
            {
                Console.WriteLine("Error getting pages: " + response.ErrorMessage);
                morePages = false;
            }
        }

        return table;
    }

And I’m trying to update a page doing this:

    public async Task UpdatePageDate(int pageId, DateTime date)
    {
        var client = new RestClient("https://myfoowebname.com/wp-json/wp/v2/"); //obviously this url is fake
        var request = new RestRequest($"page/{pageId}?Authorization=Bearer{Web.Authorization}", Method.Post);
        request.AddJsonBody(new { date = date.ToString("yyyy-MM-ddTHH:mm:ssZ") });
        var response = await client.ExecuteAsync(request);

        if (response.StatusCode != HttpStatusCode.OK)
        {
            Console.WriteLine($"Error updating {pageId}: " + response.ErrorMessage);
        }
    }

Changing POST with PUT doesn’t work either.

Any idea how to do it?
