Hi Kirlos, as you can see from the response's message field, there are two elements (id and name) underneath, you need to append .id to specify the first search field for id, so change the "message.from" to "messsge.from.id" should solve this problem.

Oh okay, I understand.
Yeah I was already trying to use the C++ SDK, and I will also be waiting for the Obj-C one.

Thank you!
