DEEP_LINK_INVALID Invalid Deep Link

The deep link URL configured for your app install or app engagement ad is malformed, unreachable, or doesn't match the app registered in TikTok's system.

What causes this error?

The deep link URL configured for your app install or app engagement ad is malformed, unreachable, or doesn’t match the app registered in TikTok’s system.

How to fix it

1. Test the deep link: Verify it opens the correct screen in your app using a testing tool.
2. Format: Ensure the URI scheme matches your app registration (e.g., myapp://product/123).
3. Fallback: Configure a web fallback URL for users who don’t have the app installed.
4. Deferred deep links: If using deferred deep linking, verify your attribution partner integration.
