Questions

FAQ

How do I use the Douyin Direct Message Deep Link API?

Send a POST request to https://api.sandbase.ai/v1/api/douyin/app-v3/open-app-to-send-private-message with your SandBase API key in the Authorization header (Bearer) and the parameters as a JSON body. You can also try it in the Playground on this page without writing code.

How much does the Douyin Direct Message Deep Link API cost?

$0.0015 per call. Every organization gets 100 free calls per UTC day, shared across eligible SandBase APIs including this one; after that each call is billed at this price from your SandBase balance. There is no subscription.

What parameters does the Douyin Direct Message Deep Link API accept?

Required: sec_uid (string) and uid (string). The Parameters table and the Playground on this page list every field.

What does the Douyin Direct Message Deep Link API return?

A JSON response returned in the same HTTP request (synchronous). The README on this page includes a sample response.

Do I need a Douyin developer account or API key?

No. Douyin Direct Message Deep Link runs through SandBase, so one SandBase API key covers this endpoint and every other API and model in the catalog. You do not need to apply for Douyin API access separately.
