Alloy Instance Name is the only field required for this extension's configuration. Alloy is the code name for the Adobe Experience Platform Web SDK. Once the SDK is installed, the "alloy" function is used to interact with the SDK. However, this function may be renamed and instantiated multiple times. As such, the Alloy Instance Name defaults to "alloy," but may be changed to suit your needs. The Alloy Instance Name field can either be configured as a string, or with a Data Element. You may define up to three alloy instances, but only one is required for configuration.
