Merchant API Product Upsert Starter — Python + Offline Checks

Rehearse a narrow Content API-to-Merchant API v1 migration before you deploy it.

Built for developers with their own Python product-upload script. Convert a supported subset of legacy product JSON into inspectable v1 request plans, catch conversion mistakes, and compare exported processed products with intended data.

INCLUDED: Python source; exact decimal price conversion; product-ID encoding; duplicate and unsupported-field checks; two synthetic product examples; expected output and drift demo; 18 regression tests; live-rehearsal worksheet; one-product send command that defaults to dry run.

REQUIREMENTS: Python 3.10+ and terminal familiarity. Offline demo needs no account, internet or pip installation.

SCOPE: online US products, USD prices, one API data source and selected basic attributes. Shipping arrays, sale prices, local inventory, account migration, authentication, developer registration, production scheduling and rollback are not included. Insert replaces product input; this is not a price-only patch.

VALIDATION: offline and mocked HTTP tests passed. NOT tested with live Merchant Center credentials or production-certified. Review the code and validate in your own account before live use. No Google approval or complete-migration guarantee.

FORMAT: one ZIP with Python, JSON and Markdown files. English. Version 1.0.0. Commercial use in your business and client implementations included; resale of the kit excluded. Independent product, no Google affiliation. AI-assisted development, reviewed and tested for this release.

Read the free preview before purchase. Individual migration work is a separate engagement after reviewing a redacted sample; not included in this download. Price is EUR 39 before any applicable checkout taxes.
