Upland Developers API is one of 2 APIs that [Upland](https://apis.io/providers/upland/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Metaverse, Web3, Gaming, NFT, and Escrow. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, an API reference, and authentication docs.

REST API for approved Upland third-party applications. Maps application users to Upland user IDs through a connection-code flow, exposes read-only player data (profile, balances, properties, NFTs, travels), manages an application-scoped escrow container (create, lock/unlock, refresh expiration, resolve, refund, remove transaction), runs Rumble tournaments (settings, create, join, scores, prize distribution, scoreboard, resolve, cancel), and queries Dev Shops, cities, neighborhoods, collections, buildings, tracks and treasures history. Application-level calls use HTTP Basic auth (App ID + Secret Key); calls acting on behalf of a player use a Bearer JWT delivered to the application's webhook URL when the player authorizes the connection.
