Hbase rest API of adding new data in table dont work - rest

Question

Truying to put some data inside the table (table is already exist) here is code (C#):
async Task AddData(HttpClient httpClient, string tableName, string columnName, string columnFamilyName, string key, string data)
{
using (var request = new HttpRequestMessage(new HttpMethod("PUT"), $"http://localhost:8080/{tableName}/{key}"))
{
request.Headers.TryAddWithoutValidation("Accept", "application/json");
var keyInBase64 = Convert.ToBase64String(Encoding.UTF8.GetBytes(key));
var columnInBase64 = Convert.ToBase64String(Encoding.UTF8.GetBytes(columnName));
var dataInBase64 = Convert.ToBase64String(Encoding.UTF8.GetBytes(data));
var columnFamilInBase64 = Convert.ToBase64String(Encoding.UTF8.GetBytes(columnFamilyName));
var FamilyAndColumnInBase64 = Convert.ToBase64String(Encoding.UTF8.GetBytes(columnFamilyName + ":" + columnName));
request.Content = new StringContent($"<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?><CellSet><Row key=\"{keyInBase64}=\"><Cell column=\"{FamilyAndColumnInBase64}=\">{dataInBase64}==</Cell></Row></CellSet>");
request.Content.Headers.ContentType = MediaTypeHeaderValue.Parse("text/xml");
var response = await httpClient.SendAsync(request);
Console.WriteLine(response);
Console.WriteLine(await response.Content.ReadAsStringAsync());
}
}
using (var httpClient = new HttpClient())
{
await AddData(httpClient, "players", "nicknames", "playerData", "somekey", "CoolGuy");
}
And here is what i got:
I already search thru google and saw a lot of github repositories but didn't find an answer.
Request of creating table and deleting it works fine.
Any ideas? Is my request correct?
Thanks.

<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?><CellSet><Row key=\"{keyInBase64}=\"><Cell column=\"{FamilyAndColumnInBase64}=\">{dataInBase64}==</Cell></Row></CellSet>
need to be
<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?><CellSet><Row key=\"{keyInBase64}\"><Cell column=\"{FamilyAndColumnInBase64}=\">{dataInBase64}</Cell></Row></CellSet>
I miss to delete "="....
