Generating Http API Access PassKey:

For Accessing Dial2Verify Http API, You would first need to get an API PassKey generated for you.
Obtaining API PassKey is an Easy & Free process.

Give a missed call to 0-4466-9494-99 using your mobile number and You should immediately receive your API key in an sms.


Sample API call:

API V2.5 generates an Image / JSON response providing a Random Dialing Number ( A random number, to which, user must give a missed call )

=JSON&cn=UK




API Parameters:

  • version : Specifies API Version number. ( This is an optional parameter, with API v2.5, support for API v1 has been removed. )
  • mobile : Specifies the telephone number to be verified. ( Ideally it should be a 10 digit Indian mobile number, But Dial2Verify API provides you with the facility to virtually validate any phone number with up-to 12 digit length)
  • passkey : Specifies the unique API Access key allotted to the developer. ( For all the versions of APIs, you can reuse the same API Access key )
  • notify : This parameter allows you to specify your custom URL, where you wish to receive acknowledgement data for once the user gives missed call to Dial2Verify verification system

    ( As soon as user gives a missed call to the allocated Dialing Number, Dial2Verify server would send a verification data to the Notification URL set above, This way, you can get Real time update of your customer verification and can Integrate the verification information to your custom databases / CRM Systems )


    Please note, URL set should be publicly available and Notification would only be sent if the missed call is received within 2 minutes of the API SID generation. In case you do not wish to receive back information, then specify 'NA' as your Notify URL
  • e-notify: With APIv2.5, you can set email notifications for every or selected missed call requests. ( this is an optional parameter )
  • out : Specifies the output response format. API v2.5 supports, JSON & IMG response.
  • cn : cn Stands for Country Name, In the recent revision to the API ( API V 2.5 ), We expanded the reach to India/ United States / United Kingdom /Italy. Hence the valid values for this parameter are,
    IN – Which generates Indian local number for missed call verification
    US – Which generates USA local number
    UK – Generates UK local number &
    IT –  Which generates Italy local number for receiving missed call
