The Dropbox Python SDK provides developers access to Dropbox for integration with other applications and devices. Dropbox is a file storage, sharing, and synching service that allows users to store, share, and sync their files.
The Google Realtime API has been deprecated, and the API will be shut down in January 2019. The company provides other products such as Google Cloud SQL, Firebase Realtime Database, and Google Cloud Firestore which should meet developers application development requirements.
Dropbox has officially deprecated the Dropbox API v1. While Dropbox encourages developers to transition to v2, and start all new builds with v2, v1 will remain available until June 28, 2017. However, all new features will be added solely to v2. The deprecation includes both Core and Business APIs.
