We will be providiing a migration path for existing OAuth1.0a partner apps to migrate to OAuth2.0. We ask that partner apps refrain from using OAuth2.0 until the migration path is available. Migrating your app will provide a smoother user experience and ensure your app retains its status in the partner program.
We're working on a range of new SDKs and sample apps that intgrate with OAuth2.0. These will be generated from our collection of OpenAPI definitions.
