Activiti tasks refer to the work items created and managed by the Activiti BPM platform as part of executing BPMN processes. They primarily represent units of work that require human input, decision making, or review, and are generated when a BPMN User Task is reached in a running process. While Activiti also supports automated execution through service and script tasks, the term “tasks” most often denotes human tasks that need assignment and completion within a process.

A typical task lifecycle begins when a process reaches a User Task and an instance of a Task is created. The task is then assigned to an individual (the assignee) or to a group (candidates). A user can claim or start the task, and eventually complete it, at which point its output is passed back to the process to drive subsequent steps. Tasks may also be delegated, reassigned, or resolved if a user is unavailable. Each task carries metadata such as name, description, due date, priority, and related process instance identifiers.

Key attributes and features associated with Activiti tasks include assignee and candidate assignment, due dates and priorities, task descriptions, form keys for task-specific input, and the ability to attach variables and local task data. Task data and state are exposed through Java APIs (TaskService) and through REST endpoints for integration with external systems, portals, or case management tools. Forms can be embedded or referenced by a form key, enabling data capture during task completion.

Historical and auditing information is stored to support reporting and governance, including completed tasks and their variables. Administrators and developers use task APIs and forms to implement human-centric workflows, approvals, escalations, and collaborative decision processes within the Activiti platform.
