This section provides a comprehensive overview of potential error codes returned by the OTPLESS API, their meanings, possible causes, and suggested corrective actions.

Error Codes

OTPLESS provides a modern approach to authentication and access management, designed for developers who prioritize both security and user experience. Our platform simplifies integration and enhances user interaction, allowing you to transcend traditional authentication with ease.

Introduction

Welcome to OTPLESS

Before you begin integrating OTPLESS into your application, complete the following initial steps to set up your environment.

Prerequisites

Get started with integrating OTPLESS by choosing the right tools for your project. Select from our range of Plugins, SDKs, and APIs to match your development needs.

Quick Start

The OTPLESS API provides a secure, efficient, and seamless way to authenticate users without the need for traditional passwords and OTPs.

A Redirect URI is a critical component in the authentication process, acting as the endpoint to which users are directed after authentication. In mobile apps, these often take the form of deep links, which bring users back to the app from a web-based authentication flow.

What's Redirect URI?

Webhooks are a powerful mechanism for receiving real-time notifications about events occurring within the OTPLESS system. By integrating webhooks into your application, you can gain valuable insights into user authentication activities and system health, enabling efficient tracking and reporting.

Integrating Smart Authentication into Your Application

Authentication via Whatsapp utilizes the WhatsApp platform to verify and identify user identity, leveraging it as a means of verification.

Authentication via WhatsApp

Authentication via Whatsapp

Initiates the authentication process by sending a magic link to the user's email address or mobile number. The magic link enables passwordless login. At least one contact method (mobile number or email) must be provided. The client must also specify a redirect URI to which the user will be directed after authentication.

Send magic link

Exchanges an authorization code for an access token, which can be used to authorize subsequent API requests.

Token Exchange

User Information

Sends an OTP to the user's mobile number or email through the specified channel. This endpoint supports sending OTPs via WhatsApp, SMS, or Email, providing flexibility in how users receive their one-time password.

Send OTP

Resend OTP

Verifies the OTP provided by the user against the orderId to authenticate. The endpoint supports verification via mobile number or email.

Verify OTP

Sends messages across different channels like WhatsApp, SMS, or Email based on the provided parameters.

Send Message

Validates user details by exchanging the token obtained from the otplessUser object for the user's information. This server-to-server call requires authentication using the client ID and secret.

Verify token
