Factors API, Send SMS Challenge vs Verify SMS Factor


I’m looking to use the Rest API to send an SMS Challenge to my phone, then verify I possess the correct challenge value.

I’ve downloaded the Postman Factors collection from the developer site, but the Challenge and Verify Post calls both have the exact same URI ({{url}}/api/v1/users/{{userId}}/factors/{{factorId}}/verify) and Body ({“passCode”: 382883"})

This seems correct for the Verify call, but not the Challenge call. Is the Challenge call not correct in the current Postman collection on the developer site?

Does anyone have the correct Challenge URI?
