Joomla 3 Virtuemart 3. Make a confirmation for the change of personal data

What there is:
- Online store running on Joomla 3 Virtuemart 3
- Account on smsc.ru. We use it to send messages. Theres a pretty simple API out there
- A test area where you can experiment.

Since the store is implemented in such a way that it will no longer be possible to update, you can make changes directly to the code.
There is no need to make modules/plugins.

What you need:
- Implement SMS confirmation when changing personal data by the user.

Result of the work:
- File archive with modified files (with the preservation of the directory structure) and, if necessary, a list of changes in the site tables.

We will provide access to the Jumla admin panel and ftp of the test zone.
If necessary, we will send a file archive of the site and a database for deployment on your site.

TK in the LS to the performer.
