Simpu's OTP API enables you to verify a mobile phone number with two-factor authentication. Create a new Verify object through the API to start the verification process of a recipient. Simpu will take care of creating a token and making sure that the message gets delivered to the recipient number.
The Verify API uses HTTP verbs and a RESTful endpoint structure with an Simpu API key that is used as the API Authorization. Request and response payloads are formatted as JSON using UTF-8 encoding and URL encoded values.
