Is UI Automation (Puppeteer/Playwright) Safe for Bulk GPSR Updates on Seller Central? Account Risk?

Hello everyone,

I’m an arbitrage/wholesale seller dealing with the upcoming GPSR compliance. Like many others, our catalog has thousands of ASINs. We tried updating the “Manufacturer Address” via Flat File (Bulk Upload), but we keep getting continuous template errors (like Error 5995 and 100632).

Since doing this manually for over 10,000 products would take months, I consulted a developer to automate the UI process. They created a custom script using Node.js, Playwright-extra, Puppeteer-extra-plugin-stealth, and fingerprint-injector.

Basically, the script logs into Seller Central and physically mimics human behavior—moving the mouse, clicking the compliance tabs, typing in the manufacturer details, and saving, all while I am away from the PC.

My main concerns before running this are:

  1. Account Health / TOS Violation: Does Amazon strictly monitor and ban for UI automation/macros on Seller Central? Even with stealth plugins and fingerprint spoofing, is there a high risk of triggering a Section 3 suspension?
  2. Detection: Has anyone successfully used similar UI automation for tedious data entry on Amazon without getting flagged by AWS WAF/bot detection?

We know the SP-API is the official route, but it seems overly complex for just a one-time data entry task. I would really appreciate any insights from tech-savvy sellers who have navigated UI automation on Amazon.

Is this a smart workaround or a ticking time bomb for my account? Thanks in advance!
