Listing, Variation and A+ Edits via SP-API with Claude for Amazon Sellers

What they did

With Claude wired to SP-API and the Ads API on his own account and no third-party tool, the seller reads sales, sessions, CVR, inventory, returns with comments, every ad search term, SQP and finances. Claude writes changes to titles, bullets, backend keywords and size attributes, created new variations (6 sizes and 2 colors on existing parents), updates A+ modules, changes budgets and negatives, and creates campaigns. Every write is logged and verified by reading it back.

How it went

He reports Claude rebuilds a full dashboard daily in about 20 minutes, published to a private page he can open on his phone, with 100% search-term coverage where his old tool showed 39%.

We only report what the source says. Results are self-reported unless noted.

Worth knowing

His rule is that Claude never changes anything in Seller Central or Ads without his explicit yes.

Copy-paste prompt

You have read/write access to my Amazon SP-API and Ads API. Rules: never write anything without my explicit "yes"; after every write, read the value back and confirm it changed; log every action.
Task: for parent ASIN [ASIN], pull the current title, bullets, backend keywords and size attributes for each child. Propose fixes for any missing or inconsistent attributes and any keyword I'm not covering from this list: [paste]. Show the diff before writing.

The source didn't publish its exact prompt. We wrote this starter so you can try the same workflow. Replace anything in [brackets].
