The Awasu API is fairly sophisticated and complex, so trial and error is going to be slow going
If you want to change a channel's setting, first use $channels/list
to find out what channels are in your Awasu and their ID's.
Then, call $channels/update
, specifying the ID(s) of the channel(s) you want to update (in the URL parameters), and what settings you want to change (in the HTTP POST data). In your case, if you want to change the min score setting, you need to include a <scoreCutoff>
To find out the format of the XML that needs to go in the HTTP POST data, call $channels/list
with a verbose=1
parameter, to get the full details for each channel. The XML structure that is returned is the same structure you need to submit when either creating new channels, or updating existing ones.
