Quick overview This workflow audits Meta (Facebook) Pixels for potential duplicate conversion counting by comparing browser Pixel vs Conversions API (server) activity and highlighting events active campaigns optimize for, then uses Anthropic Claude to generate pixel-by-pixel verification next steps and prints a prioritized audit report. How it works Runs manually to start the audit. Calls the Meta Graph API to list ad account pixels and fetch ad sets to identify the optimization events used by ACTIVE campaigns. Selects which pixels to audit (prioritizing pixels tied to optimization events, optionally overridden by a dataset ID list) and limits the scope to reduce API calls. For each selected pixel, queries the Meta Graph API for browser-vs-server event source totals and per-event counts. Classifies each pixel’s tracking setup (browser-only, server-only, or dual-source) and prioritizes pixels where optimization events may need deduplication verification. Sends the flagged pixel stats to Anthropic Claude to produce a concise JSON summary and a concrete “verify dedup” action per pixel focused on the optimization events.

Generate AI videos using Havis AI Grok Imagine

Havis AI - Grok Imagine n8n Workflow Summary This n8n workflow submits a video generation job to Havis AI Grok Imagine, waits for processing, polls task status, and returns result data when the job completes. Who is this for? Creators who want a reusable no-code generation form. Agencies building client-facing AI automation. Developers who want an importable API test workflow. n8n users connecting Havis AI output to storage, Slack, Sheets, Airtable, webhooks, or a CMS. What this workflow does Opens an n8n Form Trigger for Grok Imagine inputs. Builds a clean JSON payload and removes empty optional fields. Sends a POST request to https://havis.ai/api/grok-imagine. Waits 8 seconds, then polls https://havis.ai/api/task/{task_id}. Loops while the task is processing. Returns task ID, status, result URLs, credits used, and submitted payload. Returns a clean error object if the task fails. Setup Import the JSON workflow into n8n. Open the Form Trigger URL. Enter your Havis API key in api_key. Use only the key value; the workflow adds Bearer automatically. Fill in the model inputs and submit. For production, store the API key in n8n credentials or environment variables instead of typing it

Search Xiaohongshu users by keyword and get profile details with JustOneAPI

Use this n8n workflow to search Xiaohongshu users from a keyword and get profile details with JustOneAPI. Who’s it for This template is for creator research teams, marketing teams, creator operations teams, and automation builders who want to turn a Xiaohongshu keyword into structured user profile data inside n8n. What this workflow does The workflow starts from one keyword and searches Xiaohongshu users with the V2 user search endpoint. It extracts unique user IDs from the returned results, keeps the first unique user ID by default, fetches user profile details with the user profile endpoint, and returns a structured output for downstream use. This makes it useful for creator discovery, account research, brand research, and competitor monitoring workflows. How to set up Import the workflow into n8n. Open the Prepare API and Research Inputs node. Add your JustOneAPI token. Update keyword. Optionally adjust page and maxUsers. Leave maxUsers at 1 if you want to fetch only the first unique user result by default. Run the workflow and review the final output node. Requirements A JustOneAPI token An n8n environment with HTTP Request support How to customize the workflow You can increase
