How the connection works
The Last.app integration is in production. It is an in-house connector: Last.app tells FoodSync when something happens, rather than FoodSync asking every few minutes, and sales arrive dish by dish.
If a sale arrives twice, it does not duplicate. If one record is malformed, it does not drag the rest down. You can resend a whole day without fear of throwing anything out.
We built the integration and we maintain it. Last.app is a trademark of its owner.
