  12. Currently your App is in Staging status, meaning that you don’t have access to the credentials which are necessary for the TikTok integration. In order to gain access, click on the Submit for review on the top right corner.
  13. A modal will appear where you should enter a text, that describes what you are going to do with the App. In this particular case, you will use it to offer TikTok login option for your visitors.
  14. Press the Submit button.
  15. Wait until your App gets approved. This can take a couple of days. If you scroll up to the top of the page you will be able to inspect the Status below the App details section. If you want to learn more about the App review process, you can find more information in the official documentation.
  16. Once the Status says Live in production, you will be able to reveal the Client Key and Client Secret by clicking on the eye icon next to these fields. You will need these credentials for the provider configuration.

2. App setup

Once your TikTok app is ready you’ll need to copy and paste the Client Key and Client Secret to the TikTok provider’s Settings tab.

Once your Client Key and Client Secret has been added you need to verify the setup first. This verification helps you identify possible problems with the app.

According to the TikTok Design Guidelines, the button need to comply with some requirements. At the buttons tab of the TikTok provider there are predefined skins, which comply with those requirements, but depending on the background color you might need to choose a different skin.
The Light skin has an outline so it is suitable for both dark and light backgrounds, however the Dark skin should be used only for light backgrounds.

Common error messages returned by TikTok during verification

Verify Settings popup displays the TikTok for Developers page

The URL of the Popup will look something like this:

The “Redirect domain” that you added to your App is not correct. Check the Getting Started section of the TikTok provider and make sure you added the suggested URLs to your App!

Verify Settings popup displays a broken authorization screen

The Authorization screen displays no icons, no texts and the buttons have no labels either.

The problem is that, the entered Client Key field is not correct for your app or maybe the app with the corresponding Client Key was deleted. Go to the TikTok Developers page and open your App, and make sure the Client Key that you copied is the same as the one that you entered into Nextend Social Login!


Error: {“data”:{“captcha”:””,”desc_url”:””,”description”:””,”error_code”:10013},”message”:”error”}

The Client Secret you copied from the TikTok app is invalid. Make sure the correct one was copied!


TikTok registers accounts without email address

The TikTok API can not return email address or phone number. For this reason we are not able to get these details, so we need to register the new accounts with no email address.
If you want to avoid the accounts with no email address, then you should set the Ask E-mail on registration to “When email is not provided or empty”. This way whenever a user registers with TikTok, Nextend Social Login will display an input field where the user will need to enter an email address manually before the registration.
