JS Payment Form - Am I missing a step?

[wesfincher]

Following the example provided for the JS Integration Guide and using either the Cert or Prod link
Payment Form Example:

I receive the following error:
Uncaught TypeError: commercehub.FiservSaqAEp is not a constructor

When trying to access the JS library directly via GET, I receive the following payload response:

{ "gatewayResponse": { "transactionProcessingDetails": { "apiTraceId": "abc7a5e465ad4004a6071817f4a2a59c", "clientRequestId": "" } }, "error": [ { "type": "APIM", "message": "ApiKey and/or Authentication supplied are invalid." } ] }

It seems that a GET to the JS SDK routes through an API Gateway. The API Gateway appears to be attempting to authenticate the request but, seeing no authentication / whitelist for my host (localhost for now), returns a 401 Unauthorized.

Is this documentation up to date? What am I missing? Please and thank you!
