Atlassian has updated the Confluence and Jira Cloud APIs to comply with Europe's GDPR privacy regulations. The company will officially retire older APIs towards the end of March 2019. For now, the Bitbucket Cloud API has not been updated but the company will make GDPR-related changes to it soon.
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.
