Send weekly local review intelligence digests from Google Maps via MintAPI and OpenAI

Description

Quick overview
Monitor local competitor reviews from Google Maps, summarize complaint themes with OpenAI, and email a weekly action digest for local SEO, reputation management, and marketing teams.

How it works
Runs on a weekly schedule or is started manually.
Searches Google Maps via MintAPI for businesses matching your query, region, language, and maximum business limit.
For each business found, fetches the newest Google Maps reviews via MintAPI up to the configured per-business limit.
Filters and structures reviews to highlight low ratings and keyword-matched complaints, then builds a single prompt for OpenAI.
Sends the prompt to the OpenAI Chat Completions API to generate a Markdown report, falling back to a raw Markdown summary if OpenAI fails.
Emails the final digest to the configured recipient using your SMTP/email connection.

Setup
Create a MintAPI account and API key at https://mintapi.dev.
In n8n, create an HTTP Header Auth credential named MintAPI x-api-key header with header name x-api-key and your MintAPI API key as the value.
Create an HTTP Header Auth credential named OpenAI Authorization header with header name Authorization and value Bearer YOUR_OPENAI_API_KEY
Configure the email node with your SMTP or email credential.
Open Template Settings and update the search query, region, language, business limit, review limit, alert keywords, sender email, and recipient email.
Run the workflow manually once to verify the output, then activate the weekly schedule.
