Frequently asked questions

How is the DataSign signature generated?

DataSign is created by concatenating the request content (un‑encoded) with the APIKey, then applying MD5, Base64, and finally URL‑encoding the result.

Which encoding and content type should be used for API calls?

Use UTF‑8 encoding and set the content type to application/x-www-form-urlencoded;charset=utf-8.
