FAQ
After integration via the API, you can send us a request. In the
request, you must send your client's phone number and a 4-digit
code (if desired). Our service makes a call to the client from a
number where the last 4 digits are the code.
For example: You have sent the Vasya user number (you can pass
the client ID for easy search in statistics) 79991234567 and the
code 1255. We are making a call request from the number
X(XXX)XXX 1255. If a user on your site specifies this code, then
the ownership of his number is confirmed. It is extremely rare
that a call does not go through - you can request a replay of
the call for 5 minutes for free, while we are already dialing
from a different number capacity and country.
The call is made to the user's mobile phone, and then the request is transmitted to the server part of the provider for authentication of this user. Verification can happen automatically without even noticing the user through the SDK, or he can enter his phone number manually in the text field for verification.
