Required parameter error when calling listMarketBook

[asp]

Calling listMarketBook with these parameters. The docs indicate that only marketIds are required (I've tried just that parameter). No idea what I'm getting wrong here. Any advice welcome.

[ { "jsonrpc": "2.0", "method": "SportsAPING/v1.0/listMarketBook", "params": { "filter": { "marketIds": [ "1.211451486" ] }, "orderProjection": [ "EXECUTABLE" ], "priceProjection": { "priceData": [ "SP_AVAILABLE" ] }, "matchProjection": [ "NO_ROLLUP" ] } } ]

This is the error:

{"jsonrpc"=>"2.0", "error"=>{"code"=>-32602, "message"=>"DSC-0018"}}

Cheers.

1. There is no "filter" parameter in listMarketBook.
2. Errors in "orderProjection" and "matchProjection" parameters.
Correct request:
{ "jsonrpc": "2.0", "method": "SportsAPING/v1.0/listMarketBook", "params": { "marketIds": [ "1.211451486" ] , "orderProjection": "EXECUTABLE", "priceProjection": { "priceData": [ "SP_AVAILABLE" ] }, "matchProjection": "NO_ROLLUP" } }

Cheers mate. Will rework and test today.

Thank you, all good now. I may even understand the docs now
