External assignments
A task created by a neighbouring product carries the source badge and a link back. Its title, due date, assignee and state belong to the source product and are read only here.
Available in:Free tier “Start”

What it covers
- An idempotency key: a repeated call updates the task instead of duplicating it
- Comments, tags, time entries and project membership stay freely editable
- Deleting an external assignment removes the link and never touches the source entity
- Quick views work across products: overdue shows both tasks and instructions
- Sources: A3.Lawyer, A3.Trust, maintenance, A3.HR, A3.Sales, manufacturing
Frequently asked questions
What if the task changes in the source product?
Title, due date, assignee and state belong to the source and update from there. Comments, tags, time entries and the project are edited here freely.
Will a repeated call create duplicates?
No. An external assignment arrives with the source key, and a repeated call updates the existing task.
