IMPLEMENTATION

Call this tool

Connect a user's Langfuse account once, then configure and run Add Feedback from your backend or agent.

import { PipedreamClient } from "@pipedream/sdk"

const pd = new PipedreamClient({
  projectId: process.env.PIPEDREAM_PROJECT_ID!,
  clientId: process.env.PIPEDREAM_CLIENT_ID!,
  clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
  projectEnvironment: "production",
})

const result = await pd.actions.run({
  id: "langfuse-add-feedback",
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  configuredProps: {
    langfuse: { authProvisionId: "apn_xxxxxxx" },
    projectId: "Trace ID",
    objectType: "Object Type",
  },
})

console.log(result)
