Workday / Expensify - Postman? I am so lost, please help!

Hi,

We're trying to connect Workday and Expensify. We have the JSON link from Workday and I think our Expensify report is correct (see below - with user names removed). But anything I enter on postman is throwing errors. I don't even understand how to use postman - is this how we connect Workday/Expensify?

Would anyone be willing to meet with us? I'd be so grateful!
