Hi, There is no defined Interval that we require clients to follow. But for some calls like the Add/Revise there can be a limitation on 3-4 requests inn a few seconds. But this is defined based on a lot of rules and is client specific. You will get an error if the threshold is hit. We also recommend that each application does not spawn more than 18 simultaneous thread at any given point. Hope this helps. Cheers!! Cheers!!
