You can use the Tasks API to interact with tasks within Workfront.

Following are some examples of the most common ways of interacting with tasks through the API:

• Get task data from Workfront to use with a third-party application. This can include parameterValues or custom data.
• Update existing information regarding the task, including custom data and custom forms.
• Evaluate user availability by checking current task assignments and hours.
• Check the status of approvals.
• Track hours worked for billing purposes.

Please Note: This site is currently in beta testing and the sandbox features of the UI are not yet functional, but should be available soon.
