Salesforce Error: redirect_uri_mismatch – Comprehensive Solution Guide

Error Overview

The error message “Salesforce error=redirect_uri_mismatch&error_description=redirect_uri” typically indicates that there is a mismatch between the redirect URI specified in your application settings and the one that Salesforce is receiving. This error often arises during the OAuth authentication process, where Salesforce needs to redirect users back to your application after successful login.

When this redirect URI does not match the configured URI in Salesforce, it prevents the authentication process from completing successfully. Understanding this error is essential for developers and administrators who handle integrations with Salesforce.

Common Causes

Several factors can lead to the “Salesforce error=redirect_uri_mismatch&error_description=redirect_uri”. Here are some common causes:

1. Incorrect Redirect URI: The redirect URI configured in your application does not match the one registered in Salesforce.
2. Missing Protocol: The URI might be missing the protocol (http/https) or using a different one than expected.
3. Trailing Slashes: A trailing slash at the end of the URI in one of the configurations but not in the other can cause a mismatch.
4. Environment Configuration: Different environments (development, testing, production) may have different redirect URIs.
5. Typographical Errors: Small typographical errors in the URI can lead to this mismatch.
6. Session Issues: If the session expires or is invalidated, it may trigger the error upon redirection.
7. Salesforce Changes: Changes in Salesforce settings or updates might inadvertently affect the redirect URI configuration.
8. Multiple Applications: If there are multiple applications within Salesforce, ensure that you are checking the correct application settings.

Solution Methods

To resolve the “Salesforce error=redirect_uri_mismatch&error_description=redirect_uri”, follow the methods below:

Method 1: Verify Redirect URI Configuration

1. Log in to your Salesforce account.
2. Navigate to Setup.
3. In the Quick Find box, type App Manager and select it.
4. Locate your connected app and click on it.
5. Under the OAuth section, find the Callback URL.

7. Protocol (http vs. https)
8. Trailing slashes
9. Any typographical errors
10. Update and save any changes made.

Method 2: Update Application Code

1. Open the configuration file or code where the redirect URI is defined.

5. Test the application by attempting the authentication process again.

Method 3: Restart and Update Application
