GA4 AI Reporting Assistant for Slack
Give your team faster access to Google Analytics 4 insights without requiring everyone to navigate GA4 reports. The GA4 AI Reporting Assistant for Slack is an importable n8n workflow that turns a Slack mention into a structured analytics answer. A team member asks a question in a designated Slack channel, the AI agent selects the appropriate GA4 report, retrieves live metrics from the buyer's own property, and posts a concise response in the same Slack thread. The workflow includes three dedicated Google Analytics tools: a quick performance overview, a flexible custom report, and a field-discovery fallback for unfamiliar metrics or dimensions. The tuned English prompt adds date-range mapping, error recovery, Slack mrkdwn formatting, and rules that prevent unsupported comparisons, benchmarks, and causal claims. Ideal for marketing teams, agencies, founders, e-commerce teams, and analysts who want repeatable GA4 reporting inside Slack. Key capabilities: - Ask natural-language GA4 questions from Slack. - Retrieve sessions, active users, page views, engagement, traffic sources, devices, countries, pages, events, and other supported GA4 fields. - Receive the answer in the original Slack thread. - Use predefined reporting periods for the last 7, 30, or 90 days, today, or yesterday. - Recover from invalid field names by checking the available GA4 report fields. - Keep credentials outside the distributed workflow file. The buyer connects their own n8n, Slack, Google Analytics, and OpenRouter accounts. No seller API keys, property IDs, channel IDs, or OAuth credentials are included.
