Once connected, we pass through the last 24 hours of transactions to Xero. For older transactions, you can either manually enter your older transactions into Xero or upload your older transactions via a csv file. Our product specialists can provide you with a template that will allow you to download your Airwallex transactions and transform them into a csv file you can upload into Xero. Contact your customer success manager or customer support at support@airwallex.com if you are interested in this. You can find out how to upload previous transactions into Xero here
