TikTok’s login kit provides a simplified way for users to authenticate with the application using the existing TikTok accounts.
Implementing a localhost introduces unique issues. This blog addresses some of the common problems and provides other troubleshooting tips. The common problems are as follows:
1. Redirect URI Mismatch
The Issue: TikTok’s Login is highly dependent on redirect URLs. Upon running the application on localhost, the redirect URL may not match the allowed URLs that have been configured in the TikTok developer console.
Troubleshooting: Firstly check the allowed URLs in the TikTok developer console itself and carefully review all the allowed redirect URLs in the application. Secondly you can update the allowed URLs by adding http://localhost:3000 or even your actual port to the list of allowed redirect URLs.
In case of there is a plan to run the application on different ports while development,add http://localhost:* as an allowed URL, and while following this process take care of the security implications as doing so the risk of unauthorized access might increase.
2. Missing or Incorrect Client Credentials
The Issue: The login kit requires TikTok application ID and application secret. The issue might happen when incorrect credentials are used and are not properly integrated into application code.
Troubleshooting: Start with double checking the credentials, verify that the application ID and application secret are correctly copy and paste it from the TikTok developer console. in case with the usage of environment, variables, that stores sensitive information, ensure the accessibility and setting with the application.
3. Network Problem
The Issue: The problem of network connectivity leads to disruption in the communication between the application and TikTok’s servers.
Troubleshooting: Check out for a stable internet connection with the device, temporary deactivate any antivirus software or firewalls that might block the network traffic. Lastly, if there is usage of proxy, then check the proxy settings, which the application is handling.
4. Code Errors
The Issue: Incorrect implementation of code beneath the application can lead to authentication failures.
Troubleshooting: Debug using development tools (debugging libraries,browser’s developer console) to go through the authentication flow and helps in identifying the error in the code. Refer and go through the official documents of TikTok login kit for codes and best pratices
5. TikTok API Rate Limits
The Issue: In the process of testing there might be excessive requests generated to TikTok API that leads to encounter rate limits.
Troubleshooting: Implementation of rate limit mechanisms within the application can avoid exceeding of the API rate limits. Usage of different accounts for development and testing leads to minimized impact on applications production usage.
6. Browser-Specific Issues
The Issue: There are specific limitations or caching issues associated with few browsers which can hamper the authentication process.
Toubleshooting: Testing the application using different browsers like chrome, safari or firefox to identify the browser specific issue, clearing browser cache and cookies can help to smooth the authentication process again.
Overall Tips
- Begin with the basics by the minimal implementation of the login kit to isolate the problem.
- Use efficient debugging tools to identify network requests,cookies, JavaScript code and more.
- Connect with the TikTok developer forum when the process is still stuck, assistance from the support team with the experienced developers might help.
Conclusion
Identifying the issue and then carefully reviewing the troubleshooting steps and following them, while keeping in mind TikTok’s login kit documentation, it becomes easy to implement the login kit on the localhost environment.
