What is a key characteristic of autolaunched orchestrations?

Autolaunched orchestrations in Salesforce are designed for automation and can indeed be invoked by various methods, such as through Apex, REST APIs, or even through a Flow element. This characteristic allows for flexibility and integration within different parts of the Salesforce ecosystem and beyond, enabling automated processes to be triggered programmatically based on certain conditions or events.

Being able to invoke these orchestrations through multiple means is essential because it allows developers to integrate process automation seamlessly with existing applications and services, enhancing the overall efficiency and responsiveness of business operations.

The other options present constraints that do not apply to autolaunched orchestrations. For example, they are not limited to specific days for execution, nor do they require human interaction to operate. Additionally, while they are very much a part of the Salesforce platform, stating that they are limited strictly to Salesforce environments fails to recognize their capability to be initiated through external systems as well, thereby broadening their usability.
