01 Infrastructure

The Master Key (API Access)

To bypass the Google authentication gauntlet, we are using a Service Account. This file contains the robot credentials that allow your n8n nodes to communicate with our demo environment instantly.

n8n setup
  1. Open the text file and keep it ready.
  2. In your n8n Google node, set Authentication to Service Account.
  3. Copy the Email and Private Key (including the BEGIN and END markers) exactly as they appear in the file.
  4. Ensure both toggles at the bottom of the credential window remain OFF.
02 Data Acquisition

Download Mailchimp Brand Guidelines

We have meticulously shredded the Mailchimp Style Guide into high-precision Markdown (.md) silos. These files serve as the memory for your Brand Sentinel RAG library.

03 Record Keeping

The Brand Audit Ledger

A Sentinel without a record is a ghost. Use this Google Sheet to provide a digital paper trail of every audit your agent performs. This is your peace-of-mind dashboard for clients.
