American Express Authorization and Capture Options
There are two options for handling American Express PAYG authorizations and captures.
Implement the option that suits your business model.
IMPORTANT
American Express requires your payment technology partner
(PTP) to support nominal and full value authorizations during the Level 3
certification.
- Send an authorization request for a nominal amount.
- During the travel period, collect the rider's tap data to calculate the aggregated fare.
- Choose the request to send:
- Option 1:When the floor limit is reached, send a capture request to collect the accumulated amount.
- Option 2:When the number of trips exceeds the floor limit, send a delayed online authorization request.
- After receiving a successful response, return to step 1 to handle subsequent trips and journeys.
