For PayPal ECS the request type genericpayment is mandatory. With the first genericpayment the workorderid will be generated from the PAYONE platform and will be sent to you in the response. The ID is unique. The returned workorderid is mandatory for the following requests of PayPal Express Checkout.

Process-description:

It is mandatory to send the shipping address in the “authorization” or “preauthorization” request if the data is different to the received shipping address from the “genericpayment[action]=getexpresscheckoutdetails”. Otherwise you don’t have the PayPal sellers-protection. With “genericpayment[action]=getexpresscheckoutdetails” you only get the customer shipping address from PayPal. Use shipping address also as billing address. Your customer should have an option to change billing address while checking out. If you want to use multi partial capture, you need to set settleaccount to yes or auto, to be able to send another capture afterwards. Do not use settleaccount=no.

To use Magnes Library support with express checkout, please start the process with a generic payment request with action “setexpresscheckout” as described above. Part of the response will be the add_paydata[token] that contains the express checkout token, you need to initialise the magnes library.

In addition to the use of magnes library in express echeckout context, you can also acquire the express checkout token while using the “normal” paypal checkout. In this case, you can send an authorization or preauthorization to our server api and the response will contain the token inside the parameter add_paydata[token]. Please use this token like in the express checkout to initialise the magnes library and send data to paypal.

After initialization the magnes library will automatically send the risk payload to paypal. For further details please read the magnes library documentation provided by paypal.

The express checkout uses the complete process including generic payment requests. If you don’t want to use the complete express checkout experience, the process will start with the “place order” button.
