The tool I customized，I don't know where to config parameters in requestBody.

✔️ Expected Behavior

The tool node should have a place that allows configuring the requestBody parameter.

❌ Actual Behavior

No response

Hi @HuYiyi-337! I'm Dosu and I’m helping the dify team.

Dify's custom tool node UI does not currently support configuring raw or plain text requestBody content, which is required by endpoints like /import. The UI only exposes parameters that can be mapped to form fields (like string, number, boolean), so there's no way to directly input a block of plain text or line-separated URLs as the request body in the workflow node. This is a known limitation and has been reported by other users as well (source).

As a workaround, you can use external tools (like curl or Postman) to call such endpoints, or, if possible, adjust your OpenAPI schema to expose the requestBody as a string parameter (though Dify's backend may still not render this as a plain text input in the UI). For now, there are no advanced options or hidden settings to inject arbitrary raw request bodies for custom tools in the UI (source).

Keep an eye on GitHub issues and release notes for updates, as this is a frequently requested feature.

To reply, just mention @dosu.
