How to automatically send an SMS to the user when he visits a specific page of the site?

Question

API

Such functionality is very necessary:
​​1. The user receives a unique code (just a sequence of letters), for example adf3.
2. The system stores in memory the tablet:
adf3 -
www.abc.com/3567dh6 adf3 - www.abc.com/3g6f8j adf3 -
www.abc.com/iuh7hj
3. The user enters a special page.
4. Enters your mobile phone number into the fields, for example [phone], and the adf3 code.
5. The system completes the plate by writing a phone number in each line. In total, the table takes the form:
adf3 - www.abc.com/3567dh6 - [phone]
adf3 - www.abc.com/3g6f8j - [phone]
adf3 - www.abc.com/iuh7hj - [phone]
6. The user visits the www.abc page .com/3567dh6
7. The system looks in its plate, which phone number is registered for this page.
8. The system sends a pre-prepared SMS to this number. Sends, of course, through the SMS provider's API, for example smsaero.ru.
9. User receives SMS.
When the user enters the page again, the SMS is sent again. You can come up with a mechanism so that SMS is not sent again, but this is the next step.
Gentlemen, how can such a mechanism be implemented?
