Once the project is started, you can interact with tasks in several ways:
Make a GET request to the /tasks/assigned endpoint and identify the id of the task you want to interact with.
If you make a PUT request to the /tasks/{taskId}/reclaim endpoint, the owner of task is removed and another user from the assignee's list can accept it. The task is not reassigned automatically.
To complete a task, make a PUT request to the /tasks/{taskId}/complete endpoint.
If the tasks is rejected by all its assignees, you can update the list of assignees. Make a GET request to the /users or /groups endpoints and remember their identifiers. Then, make a PUT request to the /tasks/{taskId}/assign endpoint and provide the identifiers.
Make a GET call to the /projects/{projectId}/tasks endpoint to list all the tasks in a project by projectId. The response returns a total count of the tasks, and several details for each task: taskId, the input and outcome per task, the owner and assignees, the creation and due dates.
Make a POST call to the /projects/{projectId/target-files/{targetFileId}/versions/imports endpoint to upload (import) a new file version that can be used as part of a task. The response returns the importId which you can further use to check the import result by making a GET call to the /projects/{projectId}/target-files/{targetFileId}/versions/imports/{importId} endpoint. The projectId can be retrieved by making a POST call to the /projects endpoint, while the targetFileId can be retrieved by making a GET call to the /projects/{projectId}/target-files endpoint.
