Selldone GPT — OpenAPI schema and guide to build a custom GPT for Selldone

Selldone GPT is an OpenAPI 3.1 schema (Schema.json) plus a setup guide for building a custom GPT in the OpenAI GPT Store that connects to Selldone®. After a user signs in with OAuth, the GPT can check two-factor authentication, list the user's shops and return product details with sales statistics.

Where it fits

The GPT is one more client of the Selldone API, next to the dashboard, the storefront and the SDKs. It acts on behalf of a shop owner through OAuth, similar to a custom admin tool built with the Backoffice SDK.
