Request Parameters

Name Type Required Description
query String The query is any value of a field within a Thing which is the search criteria used to return matching things. An @ (at) symbol is considered a word delimiter and will create an OR condition in the search. For example, """". For more information and few sample of the search criteria, see Using Search.
show Array An array of field names of the data columns to return. A list of valid options is returned in the fields entry in the response structure (see below).
offset Integer The starting list offset, used for pagination. Defaults to 0 if not specified.
limit Integer Limits the number of results returned. The maximum limit you can set is 2000. Defaults to 2000.
showCount Boolean   By default, it is set to true. If set to false, the response will not include the count. Setting it to false will improve the response time but you will not know the total size of the result set.
sort String A string indicated the direction (+ for ascending, - for descending) and column to sort the results by. To sort by the key descending, use "-key". Defaults to "+name".
hideFields Boolean If set to true, the response won't include the fields in the response parameters.
useSearch Boolean   When useSearch is set to true, it will improve the performance of the operation
In some cases there is a small delay between making changes and when they will be visible to the search database, this delay is typically less than 5 seconds. As such, if you perform an update call, and subsequently call a list, you may not see the results of your operation.
iterator String   iterator is used in conjunction with the useSearch to iterate through the returned results. Initial request should be given the value new. Further requests should be given the value got in from the response.For more information on iterator and useSearch, see the example in cdp.connection.list.

If the command is sent successfully a success message and the thing is returned. Otherwise, an error and error message will be returned.
