How do I create a subtask in Asana?

Short answer: You can create subtask in Asana by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the Asana Create Subtask action to a workflow, map its 5 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.

FAQ

Questions about Create Subtask.

What does the Create Subtask action do in Asana?

Creates a subtask under an existing Asana task with name, assignee, due date, and notes. Used for templated work breakdowns.

What inputs does Create Subtask require?

Required: Parent Task GID, Subtask Name. Every input accepts a static value or a variable from any upstream node in your workflow.

Can I use dynamic inputs from earlier workflow nodes?

Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.

What happens if Asana returns an error?

The run history shows the failed step with its input and the error message Asana returned, so you can fix the input and run the workflow again. Automatic retries are built into HTTP steps only, where you can also set your own retry count and delay.

Does Create Subtask support batch operations?

Run Create Subtask inside a loop to process each item in an array. TinyCommand does not throttle calls for you, so for large arrays add a Delay step if you need to stay within Asana's rate limits.
