30 days before your business begins surcharging transactions, you must notify Qualpay that you will be adding a surcharge.
Contact Qualpay support about your intent to begin surcharging. Qualpay Support will assist you in enabling surcharging on your merchant account and can advise on the surcharge amount and how to disclose surcharging to your customers.
Note: American Express does not require prior notification. Visa, Mastercard, and Discover require that you contact Qualpay at least 30 days before adding a surcharge.
If you have a direct integration to the Qualpay API, then as of April 14, 2023, Visa requires you to send the surcharge amount in a specific field. If you send the surcharge amount through the Qualpay Payment Gateway in the amt_tran_fee field, Qualpay will map it to the correct Visa field. Visa considers the first time you send a surcharge amount in that field to be the official notification to Visa that you are surcharging transactions.
