Hi! How do I set up our ShipEngine Integration to pay Flat Rate?

We have it all synced up to ship USPS Priority but how do I tell the system within the Box ID that this is a flat Rate envelope?

I was able to figure it out by speaking with ship engine directly.The flat rate carrier package code is flat_rate_padded_envelope.
