Home Integration Methods eWay Rapid API

eWay Rapid API

Rapid API is a payment product that allows merchants to post credit card data from their customer’s browser directly to eWAY without it passing through the merchant’s server.

The integration method uses API and its custom field Option1 (or Option2 or Option3)

Please follow the integration steps only in case you are sending your customer to a different domain - e.g. asking for credit cart details at domainA.com and redirecting them to domainB.com with a payment result message.
Otherwise you can simply use the general solution.
Integration of custom field
The first step is to set custom field Option1 (or the other two in case you already use Option1). To get the needed value, you can use at least two ways - using PHP you can read it from $_COOKIE['PAPVisitorId'] or you can use JavaScript method PostAffTracker.writeCookieToCustomField() found in scripts/salejs.php. In this case you have to remember that it is a JavaScript method, so you have to get the value before sending request to eWay.
Reading response
The second step is to add the sale tracking code to the site defined as RedirectUrl. eWay will send all data there, so you have to process the response there and then use response data in the sale tracker.

PHP example here:
Rapid 3.0 API
In case you are using new Rapid 3.0 verison, you can follow the same steps above, however if you want to get the Option value from response, you have to use this code:
In case you are using Option2 or Option3, the number in above line has to change. The number is defined as N-1.
This means, for Option1 it is 0, for Option2 it's 1 and for Option 3 it's 2.
Do not forget to integrate your website with the click tracking code.
