Since some businesses use Airwallex and others use Stripe, the ability to export invoices from the Customer's Invoices page should support both integrations. Depending on the active integration, the system will display the option to export to that service.
For example with businesses connected with Airwallex, the steps will be done as follows:
Choose the invoice you want to export to Airwallex in the Customer's Invoices module.
Under the Shipping Address of the invoice, click on "Export invoice to Airwallex"
The same steps apply to businesses connected with Stripe.
After Export to shipment integration (Stripe or Airwallex). There will be a line showing "Exported to Stripe. Waiting for result"
Once the process is complete, a notification will appear in the bottom right corner with the result. You can click on it to view more details.
