Developer preview. Everything on this site describes the sandbox. The platform is switched off in production, so the API answers “feature disabled” there today. Production credentials, published SDK packages and app publishing are not available through this preview. Open the sandbox console or read the API reference.

Versioning & deprecation

The contract is versioned (the reference shows the latest v1; every published version stays downloadable). Additive changes raise the minor version. Anything that would break a client needs a new major path, never a silent change to /developer/v1.

Published versions

Version	Status
1.0.0	Published. Stays downloadable.
1.1.0	Published. Latest v1. The reference and playground are generated from this document.

Download any published version from the reference or directly: openapi-1.0.0.yaml, openapi-1.0.0.json, openapi-1.1.0.yaml, openapi-1.1.0.json, openapi-latest-v1.yaml.

What changes safely

• Adding an operation, an optional field, or a new enum value that existing clients can ignore: minor version bump, same /developer/v1 path.
• Removing a field, changing a field's meaning or type, narrowing an enum, or changing error shape: never done silently. These require a new major path (/developer/v2) and a deprecation notice on the old one, with an announced sunset date.
• Scopes only narrow across a refresh; they never widen without a new player consent.

Deprecation

A deprecated operation is marked x-release-status: deprecated in the contract before its removal date, and keeps answering correctly until that date. The changelog records every version and what changed.
