[ Prerequisites: ] [ Installation: ] [ Calling API-NG with JSON-RPC protocol ] [ Calling API-NG with Rescript protocol ]

This documentation refers to the code available at https://github.com/betfair/API-NG-sample-code/tree/master/python.

Prerequisites:

  1.  python v 2.7.2  - http://www.python.org/getit/releases/2.7.2/

  2.  urllib2 python module  - http://docs.python.org/2/library/urllib2.html

  3.  json python module - http://docs.python.org/2/library/json.html

  4.  datetime python module - http://docs.python.org/2/library/datetime.html

  5.  sys python module - http://docs.python.org/2/library/sys.html

A note on Python3:

We have added a python3 version of the json-rpc script, which is in the python subdirectory of the github sample code repo named ApiNgDemoJsonRpc-python3.py. This functions exactly the same way as the python 2.7X sample, but with compatibility tweaks for Python 3. The documentation below reflects the python 2.7X code, but the 

Installation:

You only need to clone or download the repository linked to above. If you do not have a valid Python 2.7.X installation already then please follow the download and installation instructions from the python wiki.

Run the scripts

Change to the directory where you cloned the repository to and run the sample of your choice as follows:

JSON-RPC  → 

python ApiNgDemoJsonRpc.py <appkey> <sessiontoken>

Rescript  → 

python ApiNgDemoRescript.py <appkey> <sessiontoken>

 Note:  If the command line arguments for application key and session token are not provided then the script will prompt for application key and session token

Calling API-NG with JSON-RPC protocol

Method and param values need to be changed based on the required service operation.You can execute multiple service operation together with a single call using batch json-rpc call where you can correlate the responses with value of the id.

URL = url = "https://api.betfair.com/exchange/betting/json-rpc/v1"
jsonrpc_req = '{"jsonrpc": "2.0", "method": "SportsAPING/v1.0/listEventTypes", "params": {"filter":{ }}, "id": 1}'
headers = {'X-Application': appKey, 'X-Authentication': sessionToken, 'content-type': 'application/json'}

def callAping(jsonrpc_req):
    try:
        req = urllib2.Request(url, jsonrpc_req, headers)
        response = urllib2.urlopen(req)
        jsonResponse = response.read()
        return jsonResponse
    except urllib2.URLError:
        print 'Oops no service available at ' + str(url)
        exit()
    except urllib2.HTTPError:
        print 'Oops not a valid operation from the service ' + str(url)
        exit()

        return jsonResponse

    except urllib2.URLError:
        print 'Oops there is some issue with the request'
        exit()
    except urllib2.HTTPError:
        print 'Oops there is some issue with the request' + urllib2.HTTPError.getcode()
