Business uses Calculation API call only

A business makes 1,000 Calculation API calls and doesn’t make any Transaction API calls during the month. The business is charged as API calls are made. Since no Transaction API calls were made, no rebate is applicable. In total, the business is billed for $50 that month.

Business makes 1 Calculation API call for every 1 Transaction API call

A business makes 1,000 Calculation API calls and 1,000 Transaction API calls during the month. The business is charged as API calls are made. At the end of the month, the business is rebated for the 1,000 Calculation API calls because up to 10 Calculation API calls are included for every 1 Transactional API call. The business is billed only for 1,000 Transaction API calls and charged $500.

Business makes more than 10 Calculation API calls for every 1 Transaction API call

This is an unlikely scenario but may occur if a website has a very low conversion rate or if the Calculations API is implemented in a way that it is called more than needed.

A business makes 1,000 Calculation API calls and 80 Transaction API calls during the month. The business is charged as API calls are made. The business qualifies for a rebate of 10 Calculation API calls per Transaction API call. At the end of the month, the business is rebated for 800 Calculation API calls. The business is then charged for 200 Calculation API calls and 80 Transaction API calls.
