Where can notifications be sent to through the Streaming API?

Notifications through the Streaming API can be sent to various destinations, making the correct choice comprehensive. The Streaming API is designed to provide real-time notifications of changes in Salesforce data to various applications and services regardless of where they are hosted.

Notifications can be sent to pages in the Salesforce App. This allows users within the Salesforce environment to receive updates instantly, ensuring they stay informed about changes in the data they're monitoring.

Additionally, notifications can be directed to app servers outside of Salesforce. This capability enables external systems or services to subscribe to changes in Salesforce data, allowing for seamless integration and real-time data updates across different platforms.

External clients can also receive notifications. This includes any proprietary applications or third-party systems that need to be notified of data changes within Salesforce. By utilizing the Streaming API, these clients can implement push mechanisms effectively, enhancing their capability to react to updates quickly.

The comprehensive reach of the Streaming API means that it can cater to all these scenarios, ensuring a flexible and scalable integration.
