Including the JavaScript SDK

You should include the JavaScript SDK in your HTML form by adding a <script> element in either the header or body.

There are two ways to include the JavaScript SDK:

  • Include the latest official version – Paysafe strongly recommends this approach.
  • Include a specific version.

Include the Latest Official Version

To include the latest official version of the JavaScript SDK, use the following:

<head>

	<script src="https://hosted.paysafe.com/threedsecure/js/latest/paysafe.threedsecure.min.js"></script>

</head>

Paysafe recommends this approach as you will automatically receive all the latest updates and bug fixes.

Include a Specific Version

Each specific version of the JavaScript SDK is located at https://hosted.paysafe.com/threedsecure/js/version/paysafe.threedsecure.min.js. To include one of these, replace version with the version of the JavaScript SDK you wish to use, for example:

<head>

	<script src="https://hosted.paysafe.com/threedsecure/js/<version>/paysafe.threedsecure.min.js"></script>

</head>
