Xiaohongshu APIs - Share Link Convert (V3)

prod-global

GET

/api/xiaohongshu/share-url-transfer/v1

Converts a shared RedNote note short link into a normal (resolved) note URL. This is typically used to extract the note ID from a share link for downstream APIs (e.g., Note Details or Note Comments).

Typical use cases:

• Turning user-provided share links into structured identifiers (note ID)
• Normalizing links before fetching note details, media, or comments
• Automating workflows that start from share links

Parameters

Name	In	Type	Required	Description
token	query	string	Yes	Access token for this API service.
shareUrl	query	string	Yes	RedNote share link URL to be resolved (short link or shared URL).
