Resolving 'Invalid Redirect URI' Error in Stytch

Understanding Stytch and Its Purpose

Stytch is a modern authentication provider designed to simplify the process of integrating secure authentication methods into applications. It offers a variety of authentication solutions, including passwordless login, OAuth, and more, to enhance user experience and security.

Identifying the Symptom: Invalid Redirect URI

When integrating Stytch into your application, you might encounter the 'Invalid Redirect URI' error. This error typically manifests when attempting to authenticate users, and the application fails to redirect them to the intended page post-authentication.

Common Observations

• Users are unable to complete the login process.
• An error message stating 'Invalid Redirect URI' appears.

Exploring the Issue: What Causes 'Invalid Redirect URI'?

The 'Invalid Redirect URI' error occurs when the redirect URI used in your authentication request does not match any of the URIs registered in the Stytch dashboard. This mismatch prevents Stytch from redirecting users to the correct location after authentication.

Root Cause Analysis

The root cause of this issue is often a misconfiguration in the Stytch dashboard or an incorrect URI used in the application's authentication request.

Steps to Fix the 'Invalid Redirect URI' Error

To resolve this issue, follow these steps:

Step 1: Verify Registered Redirect URIs

Log in to your Stytch dashboard and navigate to the 'Redirect URIs' section. Ensure that the URI you are using in your application is listed here.

Step 2: Update the Application Code

Check your application's authentication request code to ensure the redirect URI matches one of the registered URIs. For example, in a JavaScript application, your code might look like this:

const redirectUri = 'https://yourapp.com/callback';

Ensure 'https://yourapp.com/callback' is registered in the Stytch dashboard.

Step 3: Test the Authentication Flow

After making the necessary changes, test the authentication flow to confirm that the issue is resolved. Users should be redirected correctly after authentication.
