Params Filter

[uncletone1]

Hi, I'm having a little success with the following (C#)

String Call = "{\"jsonrpc\": \"2.0\", \"method\": \"SportsAPING/v1.0/listEventTypes\", \"params\": {\"filter\}";

Which is bringing back all the eventtypes.

I'm trying to apply a filter to bring 'BPL' and its bringing erorr 32602. Can someone help point me in hte direction of filtering correctly.

String Call = "{\"jsonrpc\": \"2.0\", \"method\": \"SportsAPING/v1.0/listCompetitions\", \"params\": {\"filter\":{\"competitionIds\": \"31\"}}}";

filter is mandatory field, so it should be filter: {} in JSON. filter is object, empty object is {}

Thanks Algo.. It was my mistake i pasted it wrong from my code.

String CALL = "{\"jsonrpc\": \"2.0\", \"method\": \"SportsAPING/v1.0/listEventTypes\", \"params\": {\"filter\":{}}, \"id\": 1}";

This works OK. (The empty object).

I'm trying to now add some parameteres to filter my search down but i'm struggling to work out the layout and the formatting.

I took a look at
https://api.developer.betfair.com/se...s-MarketFilter

and figured i could add competitionIds into the filter to restrict it down. Have i formatted it wrongly? am i using the wrong naming?

String Call = "{\"jsonrpc\": \"2.0\", \"method\": \"SportsAPING/v1.0/listCompetitions\", \"params\": {\"filter\":{\"competitionIds\": \"31\"}}}";

Thanks

If you want my advice - stop to work with JSON as string and start to work with JSON as object then serialize it. When you prepare JSON string manually, you make lots of errors.

In you case, you miss '[' and ']' for arrays. "competitionIds" is plural but you provide a single id, I think array should be provided

Thanks Algo. I will give it a shot makin the parameters.

I'm attempting the string approach to get my head around JSON first (It might seem a little strange to some but I thought it should be "human readable" (to a degree)). Once i have the basic premise of how the string should look I will start on building objects and then serialisation.

Further Question not quite related, but as i've got your attention.

Is there a way to "Trace/View" the submitted query / Response when using the Visualiser? and if possible is there tools for this process??

Thanks.
