Dharmendra Sometimes Refresh token expired while retrieving new access token.
Hi,
I'm receiving refresh token expired/invalid error while retrieving the new access token. This issue is occurring sometimes (as per what I've noticed it is occurring when no action is taken for last 1 day or more.) otherwise it works.
Please suggest me to solve this issue.
Below is code sample for retrieving the new access token using existing refresh token.

string grant_type = "refresh_token";
string data = "client_id={0}&refresh_token={1}&grant_type={2}&granularity={3}";
HttpWebRequest request = HttpWebRequest.Create(_loginUrl) as HttpWebRequest;
string result = string.Empty;
string param = string.Format(data, _clientId, refreshToken, grant_type, "best");
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ProtocolVersion = HttpVersion.Version11;
var bs = System.Text.Encoding.UTF8.GetBytes(param);
using (Stream reqStream = request.GetRequestStream())
{
reqStream.Write(bs, 0, bs.Length);
}
using (WebResponse response = request.GetResponse())
{
using (var sr = new StreamReader(response.GetResponseStream()))
{
result = sr.ReadToEnd();
sr.Close();
}
}
if (!string.IsNullOrEmpty(result))
{
var jsonSerializer = new JavaScriptSerializer();
var tokenData = jsonSerializer.Deserialize<SalesForceAccessModel>(result);
return tokenData.Access_Token;
}
