Card Capture IFrame API
JavaScript API to work with Card Capture IFrame
To initiate the Card Capture IFrame, please insert the IFrame tag into your target page.
<iframe
id="cardCaptureIframe"
height="300"
scrolling="no"
style="border: 0;"
src="{{cardCaptureIframeUrl}}">
</iframe>
To communicate with the IFrame to submit form or get results you should use postMessage browser API.
To submit Card Capture form you should trigger
submit
event.const cardCaptureIframe = document.getElementById("cardCaptureIframe");
cardCaptureIframe.contentWindow.postMessage("submit", "https://pci.channex.io");
To Validate Card Capture form you should trigger
validate
event.This validation method can be used to get validity from state from your js code. With this you can build workflows on your side based on this information. For example, you can prevent form submission if the card in the iframe is not valid.
This validation also triggers on submit event and does the same validations as you can see in real time. So, if you don't have any external logic which is based on card form validity state you can just use the "submit" method.
const cardCaptureIframe = document.getElementById("cardCaptureIframe");
cardCaptureIframe.contentWindow.postMessage("validate", "https://pci.channex.io");
To handle responses from Card Capture Form you should create
listener
function.const listener = (event) => {
if (event.origin !== PCI_PROXY_DOMAIN) {
return;
}
if (event.data.valid) {
console.log("card valid: ", event.data.valid);
}
if (event.data.success) {
console.log(event.data);
}
}
window.addEventListener("message", listener);
{
"event_type": "validate",
"valid": true|false
}
{
"event_type": "submit",
"success": true,
"card": {
"card_number": "411111******1111",
"card_token": "<token>",
"cardholder_name": "JHON DOE",
"expiration_month": "11",
"expiration_year": "2023",
"service_code": "***",
"card_type": "visa"
}
}
Param:
only|except
Value: list of card types
Default: none
You can pass additional query param for card capture iframe and configure which cards you accept. This can be done in two ways.
- 1.You can set a list of cards you accept and only these cards would be allowed to be created from an iframe.
- 2.You can provide a list of cards you want to exclude, for example American Express.
To configure the list of card types you want to accept you should provide a
only
query param with a list of card types.Example to accept only visa and mastercard:
https://pci.channex.io/api/v1/capture_form?session_token=<SESSION_TOKEN>&only=visa,mastercard
To accept all cards except some specific type you should provide
except
query params with list of card types.Example to exclude American Express:
https://pci.channex.io/api/v1/capture_form?session_token=<SESSION_TOKEN>&except=american-express
List of card types:
- visa
- mastercard
- american-express
- money-club
- discover
- jcb
- unionpay
- maestro
- link
- me
- hyper
- hypercard
So if you want just to accept all cards except American Express you need to modify your card capture iframe url to something like this
https://pci.channex.io/api/v1/capture_form?session_token=<SESSION_TOKEN>&except=american-express
Param:
