To download your receipts, follow these steps:
Use the filters at the top of the transactions screen to filter for the transactions and attachments you need and click “Export”.
The attached files in their original format (e.g. PDF, JPEG) will download in a zipped file together with the CSV file.
Each attachment has a number at the beginning of the filename. This corresponds to the number in the new “Index” column in the CSV so you can easily match the receipts to the transactions.
