A phone verification API refers to several functions that deliver patented two-factor authentication code via phone to authorize access to accounts. The API can either deliver a voice message or an OTP text message with the verification code.
Usually, the verification code is sent in real-time with short expiry duration. If users type in the code within the time frame provided, they get access to their accounts. Otherwise, it times out, and they have to request another code.
