if you get an email alerting you that an error was encountered when sending an order to DoorDash, you can share the Open Tender API request JSON with DoorDash by following these steps (see the video below):
Go to the order detail page for the order in question
Click on "API Requests" in the purple sidebar
Click on "view details" next to one of the requests to DoorDash
Copy and paste the "Request to 3rd Party API" JSON into an email and share it with your DoorDash rep
This will allow your DoorDash rep to solve the problem.
