Subscribes are limited to 4 calls per device:
NOTE: A device can register up to 4 event handlers. This means you can call Spark.subscribe() a maximum of 4 times; after that it will return false.

A user may create up to 20 webhooks in total.
Due to the ‘complexity’ of webhooks, several other limits are in place, which can be found here.
