Hi Chayce,
I've checked and do not have any such characters. In my original post above, I've actually inserted the actual XML string (only x'ed out the usertoken and any emails and names). Typically for such errors, I see XML parsing failed.
This error reads Unclosed token...that is a new one for me.
Thanks!
Have you tried to copy the payload into something like Postman to see if the actual Payload is fine and potentially something is getting corrupted in transit? Beyond that - best case is to open a ticket with QB support so they can potentially look deeper at the logs to identify what's happening. To my earlier point - if it works in one case but not another without any change to the API structure, then my best guess is that the error is content related and the something in the transfer is causing the payload not to form correctly based on the data.
