Projects are a way of organizing similar tasks, so that one can share parameters among tasks, or control what workers are allowed to work on certain classes of tasks.
The parameters associated with a project will be inherited by tasks created under that project. See Update Parameters (Project) for more information.
A common use-case is to define and update instructions at the project level and let tasks inherit from the current version of the project instructions.
To use a project for a given task, add a
project parameter when creating the task that references the project name; e.g., to associate a task with project
project: my_project to the task creation request. Note that projects created using your test API key can only be used for creating test tasks; likewise with the live API key and live tasks.
