Incorrect API Key after 100 or so quick requests

[RegularRefunds]

Hi,

I have an application that queries the Betfair API (listMarketBook) potentially thousands of times, but it gets into about 100 records, and it throws an exception with error:

"INVALID_API_KEY"

Any ideas on what the problem is? Is there a limit on how many calls I can make in a certain amount of time?

The limit for listMarketBook for any market is five times per second. Betfair only updates each market five times per second, so requesting the data more frequently is pointless.

The requests are not made for the same markets, but different markets, would this make any difference?

Hi,

Are you logging in and creating a new session before making each listMarketBook request?

Thanks

Hi Neil,

I am not logging in for every request, it is all done on the same session token. After so many requests like this my account is locked out for over 15 minutes (I'm unable to even log in to the Betfair site).

Thanks in advance


EDIT :: I am using the API-NG-sample-code project. I retrieve the session key once, which is then used for the whole procedure, however, when checking my login attempts here : https://myaccount.betfair.com/accoun...rity?showAPI=1 - there are many attempts at the same time which seems to suggest otherwise?

I'd expect a more relevant error message if you were overdoing it.

Your image with lots of logins at the same time is strange. I've looked at mine and they're all single occurrences.

I've checked our records and can confirm that you are hitting the 100 successful logins per minute ban. I'd therefore review your code and check why you might be logging in so frequently.

Thanks

Thanks for pointing me in the right direction Neil, I thought this might be the case from looking at my account, I've attached my code below. I only ever make one call for a session token, but numerous calls to listMarketBook:

private String getSessionToken()
{
String SessionToken = "";

try
{
const string postData = "username=#########&password=##########";
X509Certificate2 x509certificate = new X509Certificate2("c:\\ssl\\client-2048.p12", "#########");
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://identitysso-api.betfair.com/api/certlogin");
request.UseDefaultCredentials = true;
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.Headers.Add("X-Application", "###########");
request.ClientCertificates.Add(x509certificate);
request.Accept = "*/*";
request.Proxy = null;
using (Stream stream = request.GetRequestStream())
{
using (StreamWriter writer = new StreamWriter(stream, Encoding.Default))
{
writer.Write(postData);
}
}
using (Stream stream = ((HttpWebResponse)request.GetResponse()).GetRespon seStream())
{
using (StreamReader reader = new StreamReader(stream, Encoding.Default))
{
var jsonResponse = Newtonsoft.Json.JsonConvert.DeserializeObject<Logi nResponse>(reader.ReadToEnd());
if (jsonResponse.loginStatus == "SUCCESS")
{
SessionToken = jsonResponse.sessionToken;
}
else {
System.Media.SystemSounds.Exclamation.Play();
}
}
}
}
catch (System.Exception ex)
{
System.Media.SystemSounds.Exclamation.Play();
String getData = ex.Data.ToString();
}

return SessionToken;
}


public void UpdateSoccerMarkets()
{

// Loop through all Soccer markets
JsonRpcClient client = new JsonRpcClient(Url, APIKey, getSessionToken());

MarketFilter marketFilter = new MarketFilter();

// Set projections to be returned
ISet<MarketProjection> marketProjections = new HashSet<MarketProjection>();
marketProjections.Add(MarketProjection.COMPETITION );
marketProjections.Add(MarketProjection.EVENT);
marketProjections.Add(MarketProjection.EVENT_TYPE) ;
marketProjections.Add(MarketProjection.RUNNER_DESC RIPTION);

// Set football market
ISet<string> eventTypeIDs = new HashSet<string>();
eventTypeIDs.Add("1");
marketFilter.EventTypeIds = eventTypeIDs;

// Loop through all competitions
foreach (String Competition in CompetitionIDs())
{
// Set filter for Competition
ISet<string> CompetitionID = new HashSet<string>();
CompetitionID.Add(Competition);
marketFilter.CompetitionIds = CompetitionID;

var marketSort = MarketSort.FIRST_TO_START;

// Get markets for this Event Type / Competition
IList<MarketCatalogue> Markets = client.listMarketCatalogue(marketFilter, marketProjections, marketSort, "1000");

// Update database
EFUpdateMarkets(Markets);
}
}


I really can't understand why I am logging in repeatedly?

FIXED.

I discovered another call later in my procedures that grabbed a new session token, my bad.

Thanks for the help guys

Your code in UpdateSoccerMarkets logs in EVERY time you make the call.

You are creating a new RPC client every time you make a call to UpdateSoccerMarkets. Initialising the client calls getSessionToken which logs you in each time in order to retrieve the session id.

You should create and initialise a single RPC client outside of UpdateSoccerMarkets. You can then pass that client as a parameter to UpdateSoccerMarkets so that you are re-using the existing session.
