Loading the JavaScript Library and Invoking the Accept Function

Use the client library asset path returned by the capture context response to invoke Unified Checkout on your page.

Get the JavaScript library URL dynamically from the capture context response. When decoded, it appears in the JSON parameter

clientLibrary

as:

https://apitest.cybersource.com/up/v1/assets/x.y.z/SecureAcceptance.js

When you load the library, the capture context that you received from your initial server‑side request is used to invoke the accept function.

IMPORTANT

Use the

clientLibrary

parameter value in the capture context response to obtain the Unified Checkout JavaScript library URL. This ensures that you are always using the most up-to-date library. Do not hard-code the Unified Checkout JavaScript library URL.

JavaScript Example: Initializing the SDK

In this example,

header.payload.signature

refers to the capture context JWT.
