Stuck with passing parameters other than MarketFilter

[NickB]

Hi

I have implemented Python code to successfully call most of the API functions and return data. I have all these working when supplying a MarketFilter parameter but I am stuck on other parameters.

Here's a working example:

response = requests.post(url='https://beta-api.betfair.com/rest/v1.0/listEventTypes/', data='{"filter":{ }}', headers='snipped because private')

I have similar code working for most of the API functions but the first one I tried which has a mandatory parameter fails:

response = requests.post(url='https://beta-api.betfair.com/rest/v1.0/listTimeRanges/', data='{"filter":{ }, "timeGranularity":["HOURS"]}', headers='snipped because private')

Which returns this error.
{"detail":{},"faultcode":"Client","faultstring":"D SC-0018"}

I am guessing a simple syntax error in the way I specified timeGranularity.

Thanks for any help.

And the answer is obvious once I've reread the documentation a few times.

I should use "granularity" not "timeGranularity".
