Invoices API : Invoice Not Found

Hello!
I have our application set up to generate an order, then roll that over to a draft invoice and all works fine. When I try and publish the invoice through the API via our app, it says that the Invoice Is Not Found. When I submit the same exact data through API explorer, it works like a champ. I am stumped… anyone have any insight or ideas?

Hi @skindfw welcome to the forums!

How are you creating the first request? We’re actually receiving it as unencoded (so literally “inv%3A0-ChC78LAnrPjY7flhudv__GblEAM” instead of “inv:0-ChC78LAnrPjY7flhudv__GblEAM” which your other one is showing), so the invoice id cannot be found.
