You will simply need to upload a photo of your parking receipt through the Netlift application.
To upload the photo through the app, open the menu button on the left, and choose the Parking Reimbursement option. The latter can also be accessed by going to Perks, then Parking Reimbursement.
The reimbursement apply to monthly and annual parking spaces and the dates of validity must be visible. The refund will appear as a monthly credit in your Wallet. This credit becomes cashable the first of the next month. For example, if you have asked for a refund for the month of April, and uploaded a photo of your parking receipt, the monthly credit will be cashable on the 1st of May.
