Receipt images stored in Shared Travel Services should be extracted as part of your company's normal, monthly finance extract process. The extract will include all images that have not been previously extracted and that are attached to an extracted transaction.
When images are extracted for a particular period, they are put into a single zip file and placed in your organization's Vault Outbox for download. Each image is named after a unique serial number and kept in its native file format, ie. gif, jpg, tif or pdf.
