Client-Side Set Up {#uctp-cs-setup}
===================================

This section contains the information you need to set up the client side. You use the `Unified Click to Pay` JavaScript library to add the payment interface to your e-commerce site.  
Follow these steps to set up the client:

1. Load the JavaScript library.
2. Initialize the SDK with the JWT by passing the JWT as a parameter in the initialization method. For information JSON Web Tokens, see [JSON Web Tokens](/docs/cybs/en-us/unified-click-to-pay/developer/all/rest/unified-click-to-pay/uctp-appendix-intro/uc-appendix-jwts.md "").
