How to setup a TikTok Shop application


August 11, 2026

TikTok Shop uses different terminology than the standard OAuth2. There's no menu item labeled 'OAuth' — the OAuth 2.0 client is the 'app,' and the credentials are labeled App Key / App Secret rather than Client ID / Client Secret.

Here's the mapping and the exact path:

  • App Key = your OAuth2 Client ID
  • App Secret = your OAuth2 Client Secret
  • (You'll also see a Service ID on the same page — TikTok-specific, not part of standard OAuth)

Steps in Partner Center:

  1. Log in and make sure you're registered as an app developer (not just a seller account). If you skipped developer onboarding, the App & Service section won't behave as expected.
  2. In the left navigation, select App & Service, then click Create app & service in the top-right corner.
  3. Choose the app type. A Public app is for applications you plan to publish on the TikTok Shop App Store; a Custom app is for your own store or direct distribution to specific sellers. Both use the same OAuth 2.0 authentication and have the same level of API access. For a unified-API connector like yours, Public is the usual choice (you can convert a Custom app later if needed).
  4. Fill in name, category, target market, and set your Redirect URL to your callback endpoint. Enable API access.
  5. After creating, you land on the app detail page. Copy the App key (client ID), the App secret (client secret), and the ID / service ID shown below the app name.
  6. Separately, apply for the API permissions/scopes you need under Manage API — these are granted per-app and gate what data you can pull.

One important gotcha for you: region is split. The main Partner Center is partner.tiktokshop.com, but the US region has a separate center at partner.us.tiktokshop.com. Credentials aren't shared across them, so if your sellers span US and non-US, you may need an app in each.
