Woocommerce Sync to MYOB for invoicing

Hi SamJones, 

Thanks for reaching out, 400 bad requests is the standard response code when the API hasn't recognized your request. This is a common error that is hard to narrow down without the full error message. 

An example of a 400 bad request error message is:

{
"Name" : "TransactionsCannotBeDeleted",
"Message" : "Transactions cannot be deleted and must be reversed",
"AdditionalDetails" : "[Path]",
"ErrorCode" : 25003,
"Severity" : "Error"
}A  

 I would recommend going back to Woocommerce, if they have any issues with producing the full error message they would be able to reach out to us HERE  and with the full HTTP trace we can view our logs to obtain more details.
