Datacap Hosted WebToken

Getting started with Datacap Hosted WebToken

Include the client on your page

Add the secure, hosted JavaScript client in the <head> of your page:
<script src=""></script>

Define the required iframe control

Create an iframe and give it an ID:
<iframe id="token-iframe" frameborder="0"></iframe>
Define an input control to insert the token resulting into:
<input type="hidden" id="token" />

Define required JavaScript

Define a JavaScript callback method for token events:
var tokenCallback = function(response) {
          if (response.Error)
            alert("Token error: " + response.Error);
            var token = response.Token;
            document.getElementById("token").value = token;

Initialize the hosted iframe

Call init with your token key, iframe control ID, and token callback method:
DatacapHostedWebToken.init('[Token Key Goes Here]', 'token-iframe', tokenCallback);
Optional: Provide init with a string of your custom CSS to style the iframe contents:
var customCSS = ".card-data { background-color: #ADD8E6; color: white; }";
        DatacapHostedWebToken.init('[Token Key Goes Here]', 'token-iframe', tokenCallback, customCSS);

The layout of the iframe contents and their classes can be found here:

Note: When custom CSS is provided, Datacap’s default styling is entirely cleared.

Request a token!

Call requestToken from your page to trigger tokenization:
<input type="button" onclick="DatacapHostedWebToken.requestToken()" value="Submit" />
The response object received by your callback method looks like this:
On Success
          Token: "DC4:AADHAusosfTEnSKSVT1ro4pTxzJW6Avo9TuryyUmfheTQz05XjWQgtMbFlq405h2qcgNLb4lImhBYESG/IcztURUGbktK1/s7LDKHwnz3tpiCWeOQn+4tGppff8XWV+xtEU=",
          Brand: "Visa",
          ExpirationMonth: "12",
          ExpirationYear: "2020",
          Last4: "1111"
On Field Validation Failure
          Error: "Invalid Card Number"
On Failure
          Error: "Failed to create token"

Now that you’ve got a fresh token in your payment form, you can submit the form and process token payments on Datacap’s payment platform!
