-- Describes the connectors vended by Amazon AppFlow for specified
-- connector types. If you don\'t specify a connector type, this operation
-- describes all connectors vended by Amazon AppFlow. If there are more
-- connectors than can be returned in one page, the response contains a
-- @nextToken@ object, which can be be passed in to the next call to the
-- @DescribeConnectors@ API operation to retrieve the next page.
