Wine POS API
WinePOS offers an API and a Data Extract service, but integration is partner-mediated: no developer portal, no published spec, no self-serve keys. Inventory feeds are daily batch or FTP; only the UPS and FedEx shipping integrations use modern OAuth, provisioned in carrier portals.
Frequently asked questions
Wine POS scores D+ on the API Report Card. WinePOS offers an API and a Data Extract service, but integration is partner-mediated: no developer portal, no published spec, no self-serve keys. Inventory feeds are daily batch or FTP; only the UPS and FedEx shipping integrations use modern OAuth, provisioned in carrier portals.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly.

Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
Yes. Supergood maintains an unofficial Wine POS API and MCP server so AI agents and internal tools can read and write Wine POS data. See the Wine POS integration docs at supergood.ai/docs/wine-pos-api.
