MyOTPApp SMS API Documentation

Welcome to the MyOTPApp API! This API allows you to generate and verify One-Time Passwords (OTPs) for user authentication. This page will guide you through the two main endpoints of our API: generate_otp and verify_otp.

API Key

 To use the MyOTPApp API, you’ll need an API key. This key should be included in the header of each request as X-API-Key.

Endpoints

1. Generate OTP (POST /generate_otp)

This endpoint generates an OTP and sends it to a specified phone number.

Features:

  • Generate OTPs of a specified length (between 3 and 8 digits).
  • Set the validity period for the OTP (between 30 and 1800 seconds).
  • Use a specific message template (ID) for the OTP. This is optional.

Limitations:

  • The phone number must be between 7 and 15 digits long and cannot start with a 0.
  • The user must have sufficient balance to cover the cost of sending the OTP.

2. Verify OTP (POST /verify_otp)

This endpoint verifies an OTP.

Features:

  • Verify OTPs using either the phone number or the message ID.
  • Receive detailed status messages indicating whether the OTP verification was successful, whether the OTP does not match, or whether the OTP has expired.

Limitations:

  • The OTP must be between 3 and 8 digits long.
  • Either the phone number or the message ID must be provided.

Error Codes​

Our API uses standard HTTP status codes to indicate the success or failure of a request. Here are some of the most common codes you might encounter:

  • 200: Success. The request was successful.
  • 400: Bad request. The request could not be understood or was missing required parameters.
  • 401: Unauthorized. Authentication failed or user does not have permissions for the requested operation.
  • 402: Payment Required. User balance is insufficient.
  • 500: Internal Server Error. An error occurred on the server.
