Question

I\'m receiving the error:

If your request is larger use multipart/form-data instead:

using (var content = new MultipartFormDataContent())
{
    foreach (var keyValuePair in data)
    {
        content.Add(new StringContent(keyValuePair.Value), keyValuePair.Key);
    }

    // send POST request
    using (var client = new HttpClient())
    {
        return client.PostAsync(identifier.IsirUrl + uri, content).GetAwaiter().GetResult();
    }
}
