Ошибка redirect uri mismatch

When exchanging a code for an access token, there are an additional set of errors that can occur. The format of these responses is determined by the accept header you pass.

Note: These examples only show JSON responses.

Incorrect client credentials

If the client_id and or client_secret you pass are incorrect you will
receive this error response.

{
  "error": "incorrect_client_credentials",
  "error_description": "The client_id and/or client_secret passed are incorrect.",
  "error_uri": "/apps/managing-oauth-apps/troubleshooting-oauth-app-access-token-request-errors/#incorrect-client-credentials"
}

To solve this error, make sure you have the correct credentials for your OAuth App. Double check the client_id and client_secret to make sure they are correct and being passed correctly
to GitHub.

Redirect URI mismatch

If you provide a redirect_uri that doesn’t match what you’ve registered with your OAuth App, you’ll receive this error message:

{
  "error": "redirect_uri_mismatch",
  "error_description": "The redirect_uri MUST match the registered callback URL for this application.",
  "error_uri": "/apps/managing-oauth-apps/troubleshooting-authorization-request-errors/#redirect-uri-mismatch2"
}

To correct this error, either provide a redirect_uri that matches what
you registered or leave out this parameter to use the default one
registered with your application.

Bad verification code

{
  "add_scopes": [
    "repo"
  ],
  "note": "admin script"
}

If the verification code you pass is incorrect, expired, or doesn’t
match what you received in the first request for authorization you will
receive this error.

{
  "error": "bad_verification_code",
  "error_description": "The code passed is incorrect or expired.",
  "error_uri": "/apps/managing-oauth-apps/troubleshooting-oauth-app-access-token-request-errors/#bad-verification-code"
}

To solve this error, start the OAuth authorization process again
and get a new code.

The error 400: redirect_uri_mismatch WordPress code exception usually compromises your programming experience when the system fails to recognize the callback URL. As a result, Google OAuth does not render and launch the obtained credentials for the project, as confirmed in the error message terminating your application.However, the error 400: redirect_uri_mismatch React invalid log can also occur when setting an authentication code running on Debian with standard inputs and command lines.

So, reading this guide is critical because it teaches how to fix error 400: redirect_uri_mismatch exceptions using advanced debugging techniques and methods you can apply to all documents regardless of rendered elements.

Why Is the Error 400: Redirect_URI_mismatch Message Happening?

The error 400: redirect_uri_mismatch Postman message is happening because the machine cannot recognize the callback URL. This inconsistency prevents Google OAuth from carrying out the processes for the primary credentials.

In addition, the error log is standard when setting an authentication code running on Debian, although other programs experience it too. For example, the system displays an error 400: redirect_uri_mismatch Laravel warning when your document does not recognize the Laravel authentication code.

Although this inconsistency is typical with short projects and scripts, it can appear in advanced projects, especially those requiring authentication inputs.

Nevertheless, the error 400: redirect_uri_mismatch Firebase indicates a flawed callback URL, which affects your main document and halts further code alterations, although some values are correct. In addition, the traceback calls to pinpoint the exact failed locations and paths, which should help you implement the debugging techniques after isolating the code snippet.

Therefore, replicating the error 400: redirect_uri_mismatch home assistant warning is essential when troubleshooting the commands and finding the cause. On the contrary, you will experience a similar incorrect exception when launching an authentication code running on Debian inputs, confirming the bug’s potent characteristics.

Furthermore, this error log can terminate the generated URL object, although most values and elements in the main code snippet are correct. Henceforth, let us reproduce the error 400: redirect_uri_mismatch Gmail API exception and pinpoint the cause before introducing and exemplifying the most sophisticated debugging techniques and solutions.

– Registering an Application With an Unrecognized Callback URL

Nothing replicates the error log better than registering an application with an unrecognized callback URL. The former chapter certified the bug happens when your machine fails to recognize the specific URL due to incorrect values.

As a result, we will exemplify the error message that could help you identify the broken API console. In addition, you can use this information to avoid further complications and obstacles.

You can learn more about the warning in the following example:

As you can tell, the application uses Google OAuth 2, which should run most projects error-free. However, the active API console fails to register the redirected URL, which the system indicates via the invalid message. So, lastly, we will provide the traceback calls with redirected warnings.

The following example provides the error log:

The message helps you identify the culprit and continue the next steps to overcome the inconsistency. Still, remember the values and visual output in each operating system or project differs, so you can remain calm if the message in your program indicates different procedures.

– Setting an Authentication Code Running on Debian

The introductory chapter explained that setting an authentication code running on Debian modules launches a similar warning in your program. As a result, we will exemplify the straightforward procedure before listing the traceback calls to help you identify the flaws. In addition, the first code snippet indicates an exceeded buffering capacity, affecting the primary commands.

You can learn more about the basic commands below:

This code snippet clarifies the failed locations and prevents further code alterations. Nevertheless, you will soon learn that repairing your program takes a few minutes because the solutions work for all operating systems.

How to Repair the Error 400: Redirect_URI_mismatch Code Exception?

You can repair the error 400 redirected URI mismatch code exception by entering the authorized redirected URIs and URLs. As a result, you will reenable the failed commands and render all inputs. On the flip side, you can enter various related URLs to overcome the error log.



This section explains overcoming the mismatch broken warning is relatively easy because you can keep the code identical. Namely, you can make the changes in the application by accessing the API console. However, you must also follow a few steps to complete the debugging procedure.

The following example teaches the necessary debugging steps:

1. Locate and open the API console on your computer.
2. The machine should display a new window. Select the correct project by checking the top left corner, where you can find all projects.
3. Navigate to APIs and Services and right-click the credentials from the drop-down menu.
4. Locate and click the OAuth Client ID created for the specific application. This should be different for all projects.
5. The API console displays several sections. Click the Authorized redirected URIs section to access the next step.
6. Click the Add URI field and provide the authorized redirected URI for your project. This should clear all inconsistencies and flaws.

You can use the same approach to enter the redirected URLs, although this is only sometimes necessary when repairing the mismatch. However, we suggest adding a variety of URLs if the error persists and terminates your program. In addition, this solution prevents further complications and obstacles.

– Adding a Variety of URLs With Correct Symbols

Another excellent debugging technique suggests adding several URLs with correct symbols. Namely, the error could happen due to a single trailing slash, although this is atypical. Nevertheless, this approach should repair your document and only consists of a few steps.

You can learn more about the debugging technique below:

1. Open the Authorized URIs section to enter the URLs regardless of their number. As a result, you can introduce every version under the URL input field. We suggest adding the following URLs: https://yoursite.com/, https://yoursite.com, https://www.yoursite.com, and https://yoursite.com.
2. Navigate and click the Save button to complete the changes.
3. Repeat the technique in the former chapter to provide the URIs and repair your program.
4. Reboot your machine to allow the system to render and run the changes.

Your application should no longer experience the error log after updating the URLs and their locations. In addition, this is an excellent opportunity to provide backup paths to prevent further complications, especially with complex projects and applications.

Conclusion

The error 400: redirect_uri_mismatch code exception happens when the machine cannot recognize the callback URL. In addition, this article taught the most sophisticated solutions, so let us summarize the critical points:

• Registering an application with an unrecognized callback URL or URI replicates the broken warning
• You can repair the error 400 redirected URI mismatch code exception by entering the authorized redirected URIs and URLs
• Another excellent debugging technique suggests adding several URLs with the correct symbols

After reading this detailed guide, the error log should no longer affect your programming experience. You will also make your project future-proof due to authentication upgrades.

How do you fix Error 400: redirect_uri_mismatch? This error generally appears if you’ve not registered an ‘Authorized redirect URI’ where the response is returned or registered incorrectly in the APIs console.  

This article will explain “error 400: redirect_uri_mismatch” and present three applicable methods to fix it.

What is “400: redirect_uri_mismatch”?

The “400: redirect_uri_mismatch” error occurs when adding the Client ID and Secret to SSA at the end of the process. Typically this error is related to the URL of your website needing to be entered correctly in the API console about the newly created Client ID and Secret.

It is a problem with the URL and not your fault; Google is very particular about URLs. A trailing slash can cause this issue.

How to Fix 400 Redirect_uri_mismatch?

This error typically occurs when you do not have an authorized redirect URI registered on the APIs Console or if you have registered an incorrect redirect URI in the APIs Console. This section will present three methods to fix the error 400: redirect_uri_mismatch in WordPress.

Method 1: Enter Authorized redirect URIs

Follow these steps to fix Google OAuth 400 redirect_uri_mismatch by entering an authorized redirect URIs:

1. Go to the API Console.
2. Check the top-left corner and select the correct project.
3. Go to APIs and Services and click on Credentials.

1. Click on the OAuth Client Id you created.

1. Go to the Authorized redirect URIs section.
2. Click on the Add URI button and add your authorized redirect URI.

Try the next method if this method does not work to fix the Google redirect_uri_mismatch error.

Method 2: Adding the URL from the Error Message

Adding the URL from the error message is another method to fix the “400: redirect_uri_mismatch” error. Follow these steps to use this method:

1. Add the exact URL you see in this error message.
2. Select Save and try again. 

If this does not help, please consider testing out a variety of URLs as the next method.

Method 3: Entering a Variety of URLs

As we mentioned above, Google is quite picky regarding URLs. A trailing slash may cause this error.

Therefore, follow these steps to use this method:

1. Enter various URLs into the Authorized Redirect URIs section. You are welcome to include every version of your URL under the Authorized Redirect URIs section. Enter the following URLs:

• Trailing slash vs. no trailing slash:

https://yoursite.com/

https://yoursite.com

• www vs. no www:

https://www.yoursite.com

https://yoursite.com

1. Click on the Save button and try again when you’re done adding the variety of URIs from above.

Ryan,

Looks like my URL got cut off, here it is with line breaks.

https://oauth2.constantcontact.com/oauth2/oauth/siteowner/authorize?

response_type=code&

client_id=API_KEY&

redirect_uri=https%3A%2F%2Flocalhost%2FPATH_TO_APPLICATION

As for other code, there is no other code that really matters. If you replace API_KEY in the URL above with my real API key, you can paste this into a browser and see that:

1. You correctly get taken to an OAUTH authorization page
2. After granting access, you are redirected to the following URL:

https://localhost/PATH_TO_APPLICATION?error=redirect_uri_mismatch&

error_description=Invalid%20redirect.

If things were working, I’d get redirected to:

https://localhost/PATH_TO_APPLICATION?code=AUTH_CODE

Note that I can change PATH_TO_APPLICATION to a real app location, same result. I can also use a server with a public hostname and not use localhost, same result.

Does that help?

Problem: When trying to authenticate a user using OAuth2 through a third-party service like (Google, Facebook, etc.), the following error occurs:

Solution: A redirect_uri_mismatch error occurs when the redirect URL defined for your application at the authorization service doesn’t match the value of parameter «redirect_uri» passed by your request.

When integrating with Spring Boot, the default value of redirect_uri is set to «<ip>:<port>/login». 

In order to solve this issue, you have 2 options:

1. Define “<ip>:<port>/login” as a redirect URL under the authorization service.

2. Use a custom redirect URL by setting the following attributes in application.properties:

security.oauth2.client.preEstablishedRedirectUri=http://localhost:9090/callback
security.oauth2.client.useCurrentUri=false

In the above configuration, we set a custom redirect URI as “http://localhost:9090/callback”.
