How do I get Douyin and Xiaohongshu data into a Coze or Dify workflow without cookies?

The popular Coze workflow goes like this: paste the links of ten benchmark accounts (对标账号), collect their latest Douyin videos and Xiaohongshu notes into a Feishu table, then let the model rewrite the best ones. Step one of most tutorials says "copy your cookie from the browser and paste it here". It works for a few days. Then the cookie expires, the collection node returns nothing, and the workflow keeps "succeeding" with an empty table. Swapping that one node for an API call with a key fixes it for good.

The endpoints the workflow needs

• Douyin account profile: takes a profile URL or a v.douyin.com share link and returns the account, including its sec_uid (starts with MS4wLjABAAAA). The list endpoint needs this ID, not the 抖音号 shown in the app.
• Douyin account videos: newest videos with likes, comments and shares, about 20 a page.
• Xiaohongshu account notes: newest notes, about 20 a page, by the ID in the profile URL.

Look up each Douyin sec_uid once and store it in the table; after that the daily run only calls the list endpoints.

Registering the tool

• Dify: Tools → Custom → Create, import the schema from https://okdata.online/openapi.json, and set auth to API Key, header Authorization, type Bearer. Keep only the three or four operations you use, so the model does not pick the wrong one.
• Coze: create a plugin based on an existing service, base URL https://api.okdata.online, auth type Service with location Header, name Authorization, value Bearer okd_.... Add one tool per endpoint with id, fields and cursor as inputs.

Screen-by-screen steps for both are on the integrations page.

Cost of the benchmark-account workflow

Run	Calls	Cost
One-time sec_uid lookup, 10 Douyin accounts	10	$0.02
Daily: 10 Douyin + 10 Xiaohongshu accounts, first page	20	{{cost:douyin.users.videos.list10+xiaohongshu.users.notes.list10}}
30 days	600	{{cost:douyin.users.videos.list300+xiaohongshu.users.notes.list300}}

Test the call first

curl -G "https://api.okdata.online/v1/douyin/users/videos/list" \
  -H "Authorization: Bearer $OKDATA_API_KEY" \
  -d id=MS4wLjABAAAA... \
  -d fields=id,url,text,published_at,metrics.likes,metrics.comments

When this returns videos, the plugin or custom tool will too.

Gotchas

• Errors come back as JSON with code and message and are not charged. Add a branch for anything other than ok, so an empty table never looks like a quiet day.
• Douyin can pin older videos to the top of a profile; sort by published_at in a code node.
• Xiaohongshu hides view counts, so metrics.views is null.
• Recent Dify releases can also connect MCP servers. Whether yours can send a custom Authorization header depends on the version, so check before relying on it; the OpenAPI route works either way.
• The data is public posts only. Rewriting other people's content for your account is your call; copying it word for word is not a good one.

Other ways

The Coze plugin store has Douyin and Xiaohongshu plugins; some are free and some ask for your cookie, which brings back the original problem. Feishu's own automation can pull from an HTTP endpoint too. For ten accounts checked once a week, a person with a spreadsheet is still a fine answer. All workflow tools are covered under integrations.
