To create a supplemental feed in Merchant Center with Claude or ChatGPT, connect your Google Merchant Center account to PaidSync.ai and ask the assistant to create a supplemental feed, which layers overrides over your main feed. It changes your account on the first call, so read the request before you approve.
Supplemental feeds let you override attributes without touching the main feed. A write tool creates one:
merchant_list_data_sources finds the primary source to reference.merchant_create_supplemental_feed creates a supplemental source with a name, feed label, language and optional primary source to reference.merchant_list_data_sources only reads your account. merchant_create_supplemental_feed changes it. That is the full set you need to create a supplemental feed.
| Tool | What it does |
|---|---|
| merchant_list_data_sources | Finds the primary source |
| merchant_create_supplemental_feed | Creates the source |
Use it for promotions, margin labels or title tests. Rows come after the source exists.
These steps use Claude to create a supplemental feed. PaidSync.ai also works in ChatGPT, and the prompts are the same.
