Read and write describe what an operation does to your books, not how it is sent: some read operations are sent as POST requests and still only read. A write is posted to BUSY only through an operation built for it.

Every paid price is for an exact combination of billing period, companies, financial years and enrolled devices, in Indian rupees with 18% GST extra. Services you use through your own accounts, such as Pusher, Google or a messaging provider, have their own pricing.
