Verify API 제공

The Verify API enables you to confirm that you can contact a user at a specific number.

  • Protect against spam, by preventing spammers from creating multiple accounts
  • Monitor suspicious activity, by forcing an account user to verify ownership of a number
  • Reach your users at any time, by ensuring that you have their correct phone number

The general workflow is shown in the following sequence diagram:

verify 자체개발 vs verify api 사용

  • verify 자체 개발시 난수발생(4자리,6자리) and 메모리db에 임시저장 확인시 조회 and 로그 자체기록

  • verify api 사용시 따로 메모리db 구축안하고 돈이 더 들어간다. 성공시 0.1 유로? 비싸다. 그냥 sms보내면 0.04유로
    대신 분석 및 로그조회가 가능하다
