The customer's CMS system can integrate with Digital Paymeter via JavaScript libraries.  The intended metered page includes an html script tag that loads the Digital Paymeter SDKs.

The initial script source (syncwall) is loaded by the metered page and then takes care of loading the key JavaScript libraries that provide the actual page metering.

The page metering business rules are executed on the server.  The PaymeterSdk interacts with the server APIs to run the business rules and then interpret the results.  Based on those server results, the PaymeterSdk might use functionality in the OverlaySdk to trigger UI elements (modal pop-ups, fly out alerts, etc.).
