This is my first time trying to create a subscription with the REST api and I'm getting an error stating: "You must enter at least one line item for this transaction." I have entries for

subscriptionLine

and

priceInterval

and I'm using values that I copied from an existing subscription. Does anyone see anything obvious that I'm missing with this request?

Seems odd -- and a shot in the dark... remove the lineNumber -- I've had some oddities with that

I'm going to hang my head in shame here. I worked on this a loooong time only to find out that I was sending subscription data but hitting the invoice endpoint. This is what I get for copying a request in Postman and not paying attention. facepalm

😜 that happens to everyone I think. Good find
