Enter a public network URL, for example, http://example.com/notification/action. HTTP/HTTPS subscribers must confirm their subscriptions. For details about HTTP/HTTPS messages, see Introduction.
SMS
Enter a valid mobile number preceded by a plus sign (+) and a country code.

Note
To prevent malicious users from attacking subscription endpoints, SMN limits the number of confirmation messages that can be sent to an endpoint within a specified period of time. For details, see Traffic Control over Subscription Confirmation.
SMN does not check whether subscription endpoints exist when you add subscriptions. However, subscribers will not receive notification messages until they confirm their subscriptions.
After you add a subscription, SMN sends a confirmation message to the subscription endpoint. The message contains a link for confirming the subscription. The subscription confirmation link is valid within 48 hours. Confirm the subscription on your mobile phone, mailbox, or other endpoints in time.
