Hi We are getting the same issue when attempting to send customer_invoice. We tried both API V1 and V2 but received the same error as mentioned by Junxie above: ExceptionType: 'IPPException' ExceptionMessage: 'Invalid Token' ExceptionFaultCode: '12010' Token generation is successful with both APIs, but when we try using these tokens to send the request, we receive this error message. I haven’t been able to find any guidance on resolving this error. Thank you ... View more
