Google Merchant Center

Google Merchant Center API integration with managed OAuth. This is a write-capable integration — it can read, create, update, and delete products, inventories, data sources, promotions, account settings, and conversions in Google Shopping. Use this skill when users want to interact with their Merchant Center data. All write operations (creating/updating/deleting products, inventories, promotions, data sources, or account settings) require explicit user approval with specific resource identifiers before execution. For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway). Requires network access and valid Maton API key. Calls run through the `maton` CLI with OAuth login, or over raw HTTP with a Maton API key where the CLI cannot be installed. Every call is authenticated as the user's connection and reaches only what that connection's authorization allows, which the provider enforces on every request; the endpoints documented here are the ones this skill uses, and any other endpoint of this app needs the user to ask for it by name. Default to read and list calls, and confirm every write or new connection with the user. This file also documents the three constructs that turn a Google Merchant Center connection into automation, in the order they are used: the connection (the first step), a hosted function that runs a Google Merchant Center action through the Maton SDK, and a trigger that calls that function on a schedule or on an event. Those sections are the platform's own reference text, shared with the api-gateway skill, with Google Merchant Center examples; they add no Google Merchant Center capability - Google Merchant Center is not an event source, a trigger cannot read Google Merchant Center data, and the files under `references/<source>/triggers.md` are the platform's event catalogues for the sources Maton offers (time, Calendly, GitHub, Gmail, HubSpot, Linear, Notion, Slack, Stripe).
