Allowed values:

pendingapprovedrejectedchanges_requested

Example:

pending

assignee_status

enum<string>

optional

The external field allows you to store app-specific metadata on tasks, including a gid that can be used to retrieve tasks and a data blob that can store app-specific character strings. Note that you will need to authenticate with Oauth to access or modify this data. Once an external gid is set, you can use the notation external:custom_gid to reference your object anywhere in the API where you may use the original object gid. See the page on Custom External Data for more details.

Example:

{"data":"A blob of information","gid":"my_gid"}
