How a Google Calendar and Trello automation gets built
- Describe the outcome. Say what should happen — not which endpoints to call. HumDay works out which operations each side needs.
- Approve the contract. Before anything is built you see exactly what it will do in Google Calendar and Trello, and what it will never do.
- See it proven. The program runs and shows you the result before it is allowed near either live account.
- Grant access, then go live. You approve the specific operations it may use on each side — and only those.

- No. There is no node graph to wire up and no field mapping to do. You say what should happen and HumDay works out which operations it needs from each side.

- Google Calendar publishes 37 documented operations and Trello publishes 324. HumDay only ever uses the specific ones your approved contract needs.
