Gameflip

Gameflip is a digital marketplace where gamers buy and sell games, in-game items, gift cards, game accounts, boosting/coaching gigs, and other digital goods, backed by an escrow-style buyer guarantee and a built-in wallet. For developers and power sellers, Gameflip publishes the GFAPI — a JSON REST API (base path /api/v1) for creating and managing listings, searching the marketplace, running exchanges (sell/buy records), reading account profiles and wallet history, and handling Steam item escrow and bulk trade-offer listings. Requests are authenticated with an API key plus a rotating TOTP one-time password sent in the Authorization header (`GFAPI :`). Access is Beta and gated: API keys and TOTP secrets are issued to selected developers through Gameflip support / account settings. An official Node.js client library (gfapi) with sample code is published by Gameflip.

Gameflip publishes 6 APIs on the APIs.io network, including Account API, Exchange API, Listing API, and 3 more. Tagged areas include Company, Gaming, Marketplace, Digital Goods, and E-Commerce.

Gameflip’s developer surface includes getting-started guide, documentation, API reference, support, engineering blog, signup flow, authentication, and 9 more developer resources.
