Thank you Dennisedson,

I tried to add the parameters and make the call. In response it said it expects an offset from the previous call. Then I called again without any parameters but only the api key ‘demo’. It returned an offset at this time. Then I added the offset to the actual call with other parameters and it returned the inteded list.

The question is, is it the right way (getting offset value without other parameters, then adding that parameter with the actual call) to obtain the subscription list for a given timespan? It looks like the first call without any parameters obtains a key (offset), which is to add to the second call so that it opens the door of the subscription list for a given timespan. Is that the way it is, or am I making any mistake?

Best regards,

Mehedi
