Confirm your phone number with a call

For various types of operations, such as password recovery, authorization in public Wi-Fi networks, confirmation of money transfers, logging in to your personal account, and so on, you need to send authentication data. Using our API, you can organize the procedure for confirming the phone number by calling the subscriber himself.

To create a request to receive a phone number, at which the subscriber will have to make a confirmation call, you need to call the address using the GET or POST method:<login>&psw=<password>&phone=<phone>
The following parameters are passed to the server:

OptionThe value
loginCustomer Login.
pswClient Password (you can add or change it on this page).
phoneThe phone number of the subscriber from which the confirmation call will be made.

If an error occurs, the Server returns the following string:
  • ERROR = N (description)

  • When fmt = 1:

  • When fmt = 2:

  • When fmt = 3:
    "error": "description",
    "error_code": N
N Ц error number, can take the following values:

The valueDescription
1Error in parameters.
2Invalid username or password. Also occurs when trying to send a message from an IP address that is not included in the list of allowed by the Client (if such a list was previously configured by the Client).
3Insufficient funds on the Client's account.
4The IP address is temporarily blocked.
5The specified phone number of the subscriber is in the black list of the Client.
9Attempt to send more than fifty identical requests to get a phone number for confirmation within a minute.
This error also occurs when you try to send fifteen or more requests simultaneously from different connections under the same username (too many concurrent requests).

If the request is successful, the Server returns a response in the form of a string.

  • when fmt = 0: phone = <phone>, all_phones = <all_phones>

  • when fmt = 1 (the first is the number to which the subscriber needs to call): <all_phones>

  • when fmt = 2:

  • when fmt = 3:
    "phone": "<phone>",
    "all_phones": [

<phone> Ц the phone number to which the subscriber must make a call within 15 minutes to confirm their phone number.
<all_phones> Ц a list of all possible phone numbers, one of which was assigned by the system to call the subscriber (depending on the country).

After the subscriber's call, the Server records the fact of the call in the form of an incoming message with the text "[waitcall] " and sends all the necessary information about this call to the Client's handler.

The server does not accept more than fifty identical requests to get a phone number for confirmation within a minute to reduce the load and protect against errors and loops in the Client-side program.
