You have the ability to set multiple Service Fee tiers for your Website so that Orders with varying amounts can have different fees charged.
Step 1) Click the Service Fees tab under the Checkout Menu Category.
Step 2) Select which API Credential (Website) you would like to adjust.
Step 3) Click Edit. Rename the Fee Description if you would like. Enter in the Percentage Service Fee you would like to apply to an Order and the Floor Price that Order must hit to have the Service Fee applied.
Step 4) Edit or Add Additional Service Fees if necessary.
(Example: Order Total = $100 --> Service Fee = $15)
(Example: Order Total = $200 --> Service Fee = $24)
