Regarding Blockchain.info's Receive Payments API V2:

The 'Generating a Receiving Address' feature requires a callback\_url, to which they send a notification of EVERY confirmation. For every transaction, potentially thousands of notifications will be sent to the callback\_url.

1. When I use the 'Generating a Receiving Address' feature, can I receive a new address WITHOUT specifying a callback\_url?
2. If I must specify a callback\_url:
   a. Is there any way to cancel the callbacks?
   b. Can I limit the number of notifications that are sent?

2) your callback url must respond with the text `"*ok*"` without quotes and nothing else, just text. This will stop Blockchain.info from sending further notifications.
