This page explains some key terms related to the Telesign Verify API, lists the verification methods it supports, and directs you to further usage instructions depending on the primary verification method you want to use.

Key terms

  • Verification process: A transaction that uses the Verify API to evaluate one recipient. This may include multiple attempts, sequentially using each of the verification methods configured in the applicable verification policy.
  • Verification policy: The account-specific configuration of the Verify API applied to a verification process. This includes which verification methods to use, in what order to use them, and the length of timeouts between attempts. Your account has a default verification policy, which you can contact your Telesign rep to change.
  • Verification method: One of the Telesign verification services that a given verification process may use (Silent Verify, SMS, etc.) We encourage specifying a backup verification method, such as SMS one-time passcode (OTP), in case your primary verification method fails.
  • Mobile app token: An access token that your instance of the Telesign Android SDK must include when making requests to the Verify API. Telesign provides this to you in the HTTP response to your original request to the Verify API that initiates a verification process. Each mobile app token expires after five minutes and is unique to one verification process.
  • Security factor: A token you pass on to Telesign, as an element to be used in the verification process. When using an OTP verification method such as SMS, the security factor is the end user's asserted one-time passcode (OTP).
