Delivers patented phone-based verification and two-factor authentication using a time-based, one-time passcode sent over SMS
An API that delivers patented phone-based verification and two-factor authentication (2FA) using a one-time passcode (OTP) sent over voice message in the event the end-user chooses the voice method, provides a landline or is not authorized to receive SMS messages in a specific country.
BotDelive is a cloud communication platform for developers. It allows developers to send and receive 2FA and Push Notification via chatbots.

As part of Twilio's account security offerings, the Twilio Verify API makes it simple to add phone verification to your web application. It supports codes sent via voice and SMS.
Over the years, businesses have relied on email verification to prove ownership of a new account. However, email verification alone does not provide the needed security to verify account ownership and prevent fraud. Therefore, in conjunction with Google, developers have created automated Application Programming Interfaces that require phone number verification to validate new account ownership.
Phone verification APIs are increasingly used by businesses that require a higher level of security. Phone number verification APIs generally make the sign-up and sign-in process friction-free for both users and the website or business owners.
These APIs are applications that deliver a patented phone-based verification and 2FA authentication featuring a voice and SMS using a one-time code. A user chooses whether they will receive the code through a voice call or via SMS, and in a timed session, they then send this back to verify they are real, and the account is authentic.
Here is how a phone number verification API works:
These codes are typically timed so that if the phone number does not belong to the users, it times out. The code can still be read to people using landlines in an automated voice through a call. But since most phones can receive text messages universally, the codes are sent to users via SMS unless otherwise noted.
These APIs are for any business and website that want to increase their account registration security and curb fraudsters. These APIs are mostly used by application developers, business websites, and payment processors who want to ensure secure lead verifications, transactions, and avoid spammers. Top companies such as Microsoft, Facebook, Twitter, and Google have incorporated phone number verification in their sign-up and sign-in processes.
There are several reasons why Phone verification APIs are important. They include the following:
These verification APIs give users the ability to integrate voice and SMS messages and end-to-end handling of phone numbers, building a database. It provides a communication link, and with SMS verification API, users can reach out to their customers after the sign-up with personalized messages to promote the relationship.
