Betfair Free API

[Trilobite]

Here is the xml as it is sent (token not real), without the VB6 Quote handling stuff i have to use :

<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><logout xmlns="https://api.betfair.com/global/v3/BFGlobalService"><request><header><clientStamp>0</clientStamp><sessionToken>0123456789</sessionToken></header></request></logout></soap:Body></soap:Envelope>

To me it doesn't look in any way like a proper response to the Logout call (even a wrong one). The only thing I suggest is...

set http header SOAPAction to https://api.betfair.com/global/v3/BF...Service/Logout

and send http post request to https://api.betfair.com/global/v3/BFGlobalService

I think yours is different to this but I've just had a quick look.

[arcadia00]

Sorry, do you have the API6 reference guide?

http://bdphelp.betfair.com/API6/6.0/...tml/wwhelp.htm

Look at

The Connection End-point URLs for the API

you seem to be using an old old one with
https://api.betfair.com/betex-api-public-ws/BFService

I'm slightly confused as you've said Login & GetMarketPricesCompressed is working for you so I'd've thought they might not work too if you're POSTing to an old URL.

[Trilobite]

That did it mate

It was the MakeSOAPRequest "POST" function that was wrong.

changed it from :

oHTTP.open "POST", "https://api.betfair.com/betex-api-public-ws/BFService", False

to

oHTTP.open "POST", "https://api.betfair.com/global/v3/BFGlobalService", False

and was logged out OK



Return was :

<?xml version="1.0" encoding="UTF-8"?> <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:n2="http://www.betfair.com/publicapi/types/global/v3/" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><n:logoutResponse xmlns:n="http://www.betfair.com/publicapi/v3/BFGlobalService/"><n:Result xsi:type="n2:LogoutResp"><header xsi:type="n2:APIResponseHeader"><errorCode xsi:type="n2:APIErrorEnum">OK</errorCode><minorErrorCode xsi:nil="1"></minorErrorCode><sessionToken xsi:nil="1"></sessionToken><timestamp xsi:type="xsd:dateTime">2008-05-17T10:27:39.169Z</timestamp></header><minorErrorCode xsi:nil="1"></minorErrorCode><errorCode xsi:type="n2:LogoutErrorEnum">OK</errorCode></n:Result></n:logoutResponse></soap:Body></soap:Envelope>

So do we need to change the "POST" url address for different API requests then ?

Or will that one now cover getting the horse racing market, getting the pricescompressed and placing the bet ?


Thanks again mate

Yes both login and pricecompressed working fine, updating fine in-running using that old address .

Iam using Betfair Sports Exchange API 5.5 Reference Guide.chm

There are 3 URLS one for global calls like login logout keepalive, one for exchange calls which is most others, and one for australian events like if you want GetMarketPrices for the Melbourne Cup. Which is just daft.

https://api.betfair.com/global/v3/BFGlobalService

▪	https://api.betfair.com/exchange/v5/BFExchangeService

▪	https://api-au.betfair.com/exchange/...xchangeService

Thanks, just reading The Connection End-point URLs for the API Services part now.

So its a simple update to make two MakeSOAPRequest functions, one for Global and one for Exchange url's.

Cheers

[Trilobite]

Ok that was a quick change, all ok now using 2 functions for the 2 url's

I wonder if the old url i was using has an advantage being that everyone else will be using the proper url that is documented ?

Its something i will keep in mind if there are problems using the proper url !

[Trilobite]

Does this look like a working placeBet call ?

Does it work? What's there looks right, if it doesnt work, you may need to add fields for betCategoryType & betPersistanceType. See the ArrayOfPlaceBets structure in the docs.

Day 4 i think, and i learn a bit more

If you right click the Sports API 6 (UK Exchange Services) WSDL link on the Free Access API developers page and Save As....

You end up with a file called BFExchangeService.xml

Open this in Iexplorer and you get to see all correct format to send the XML in, and also see the responses you can expect to get back.

Ive been using the API 5.5 help file, which doesn't have the placeBet format as the API 6 below.

- <xsd:complexType name="PlaceBets">
- <xsd:sequence> <xsd:element name="asianLineId" nillable="false" type="xsd:int" /> <xsd:element name="betType" type="types:BetTypeEnum" /> <xsd:element name="betCategoryType" type="types:BetCategoryTypeEnum" /> <xsd:element name="betPersistenceType" type="types:BetPersistenceTypeEnum" /> <xsd:element name="marketId" nillable="false" type="xsd:int" /> <xsd:element name="price" nillable="false" type="xsd:double" /> <xsd:element name="selectionId" nillable="false" type="xsd:int" /> <xsd:element name="size" nillable="true" type="xsd:double" /> <xsd:element name="bspLiability" nillable="true" type="xsd:double" /> </xsd:sequence> </xsd:complexType>

Thanks for all the help on this thread, iam up and running now, did my first trades last night


I thought i would post the placeBet xml string i successfully used, just in case anyone has found their way to this thread via google etc


Its the same string for the Lay bet, you just change the betType xmlns part from a B to an L and make sure the bspLiability xmls covers the LAY Liability amount.



placeBet:

<?xml version="1.0" encoding="utf-8"?> <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <soap:Body> <placeBets xmlns="https://api.betfair.com/exchange/v3/BFExchangeService"> <request> <header xmlns=""> <clientStamp>0</clientStamp> <sessionToken>01234567890=</sessionToken> </header> <bets xmlns=""> <PlaceBets xmlns="http://www.betfair.com/publicapi/types/exchange/v3/"> <asianLineId xmlns="">0</asianLineId> <betCategoryType xmlns="">E</betCategoryType> <betPersistenceType xmlns="">IP</betPersistenceType> <betType xmlns="">B</betType> <bspLiability xmls="">2.00</bspLiability> <marketId xmlns="">99999999</marketId> <price xmlns="">3.3</price> <selectionId xmlns="">99999</selectionId> <size xmlns="">2.00</size> </PlaceBets> </bets> </request> </placeBets> </soap:Body> </soap:Envelope>

The Return xml from the server:

( iam not sure why the success xsi:type part came through split by a CrLf, but i will have that covered by stripping out invalid characters like that )

<?xml version="1.0" encoding="UTF-8"?> <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:n2="http://www.betfair.com/publicapi/types/exchange/v3/" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <soap:Body> <n:placeBetsResponse xmlns:n="http://www.betfair.com/publicapi/v3/BFExchangeService/"> <n:Result xsi:type="n2:PlaceBetsResp"> <header xsi:type="n2:APIResponseHeader"> <errorCode xsi:type="n2:APIErrorEnum">OK</errorCode> <minorErrorCode xsi:nil="1"/> <sessionToken xsi:type="xsd:string">0123456789=</sessionToken> <timestamp xsi:type="xsd:dateTime">2008-05-19T18:10:33.153Z</timestamp> </header> <betResults xsi:type="n2:ArrayOfPlaceBetsResult"> <n2:PlaceBetsResult xsi:type="n2:PlaceBetsResult"> <averagePriceMatched xsi:type="xsd:double">3.3</averagePriceMatched> <betId xsi:type="xsd:long">999999999</betId> <resultCode xsi:type="n2:PlaceBetsResultEnum">OK</resultCode> <sizeMatched xsi:type="xsd:double">2.0</sizeMatched> <success xsi:type="xsd:boolean">tru

[arcadia00]

Maybe you can help me. Let me ask you the question without poisoning your mind with what I am doing wrong. How would you set up a single PlaceBets call so that you requested a normal lay; then have any unmatched portion (or all if none at all was matched) become a BSP (Betfair Starting Price) lay at off time.

[Trilobite]

Iam not sure, is that handled by the betPersistenceType
