    Definitions of Input and Response Parameters

    • Limit and Offset
      These parameters are used for paging control. "Limit" indicates the maximum number of entries returned at a time, and "Offset" is the offset value. If the number of results exceeds the Limit, the number of returned results equals to the value of Limit.
      For example, if Offset=0 and Limit=20, the 0th to 19th entries are returned; if Offset=20 and Limit=20, the 20th to 39th entries are returned; if Offset=40 and Limit=20, the 40th to 59th entries are returned and so on.

    • topic.N
      Format for inputting multiple parameters at a time. The format below indicates an array parameter, which means multiple parameters can be input at the same time. The inputting format is:
      topic.0=test1&topic.1=test2&topic.2=test3, and so on (start with the subscript 0).
