"content": "## Sync Asana task due dates to Google Calendar\n\n### How it works\n\n1. A schedule trigger runs every 15 minutes and reads the target project and calendar from one config node.\n2. It pulls every Asana task in the project with its due date, completion state, and assignee.\n3. It lists the calendar events this workflow already created, matched by the `asana_gid` token in each event.\n4. A code node compares the two sets and decides, per task, whether to create, update, or delete an event.\n5. A switch routes each task to the matching Google Calendar action, so a task never gets a duplicate event.\n\n### Setup steps\n\n- [ ] Add an Asana Personal Access Token credential and select it on the `Get Asana Tasks` node.\n- [ ] Add a Google Calendar credential and select it on the three calendar nodes.\n- [ ] Open `Set Sync Config` and set your Asana project GID and target calendar ID.\n- [ ] Run the workflow once to backfill, then activate it.\n\n### Customization\n\nChange the schedule interval, point it at a different project or calendar, or edit the event title and description in the `Reconcile Tasks and Events` node.",
