Recipes will poll the app for trigger events the moment it is turned on, and subsequently, every 10 minutes for the community and base plan, and every 5 minutes for Professional and above plans.
Tip
When you are testing, 10 minutes can seem like a long time! To pick up new invoices immediately instead of waiting 10 minutes, you can stop and start the recipe, as the act of starting the recipe will make it poll the app immediately.
