Instead, we want to use one of their two "supported" methods, both of which leverage the same SS 1.0 plug-in. It's possible to use the plugin directly in a SS1 script, or we can call the restlet, which frees us from the restrictions of SS1. My only concern was how much code is needed to authenticate and call the restlet using TBA from JavaScript. Unless there are libraries that make it easier? My past restlet integrations have all been written in Java, Groovy, C# or Apex. I haven't tried to do it from a SuiteScript.
