Which REST API method would be used to execute a job in Planning?

The method for executing a job in the context of using REST APIs in Planning is typically the POST method. This is because POST requests are used to create new resources or trigger operations that have side effects, such as executing jobs. When you want to trigger a job, you would send data along with the request to indicate what action to perform, which aligns with how POST is designed to operate.

While EXECUTE might seem like a logical choice due to its descriptive nature, it is not an actual HTTP method defined by the REST standards. REST APIs utilize standard HTTP methods—GET, POST, PUT, and DELETE—where POST is specifically designated for actions like initiating jobs or submitting data that results in a state change on the server.

GET is primarily used to retrieve data without causing any side effects, which does not align with the purpose of executing a job. PUT is employed to update existing resources, which also does not apply to job execution since this involves creating a new operation rather than updating an existing one.

Thus, POST is the appropriate method for executing a job in Planning, as it fulfills the requirements of creating or triggering an action on the server related to the execution of jobs.
