Get task list

GET

Retrieve a list of tasks.

You can use the query parameters to filter the list by project and/or view (a tab within the Data Manager). You can also optionally add pagination to make the response easier to parse.

The project ID can be found in the URL when viewing the project in Label Studio, or you can retrieve all project IDs using List all projects. The view ID can be found using List views.

    Example: {"conjunction": "or", "items": [{"filter": "filter:tasks:completed_at", "operator": "greater", "type": "Datetime", "value": "2021-01-01T00:00:00.000Z"}]}
