The renderDecisions property allows you to force the Web SDK to render any personalized content that is eligible for automatic rendering.

Set the renderDecisions boolean when running the sendEvent command. If omitted, this property defaults to false. Set this property to true if you want to automatically render personalized content.

IMPORTANT
The renderDecisions property is incompatible with the documentUnloading property. Avoid setting both properties to true simultaneously.
alloy("sendEvent", {
  "xdm": adobeDataLayer.getState(reference),
  "renderDecisions": true
});

Make sure that when setting this property to true that you also include associated scopes or surfaces. These scopes or surfaces can be requested automatically (such as on the first sendEvent command on a page), or explicitly (using personalization.decisionScopes or personalization.surfaces). A common issue when rendering personalization is the following scenario:

  1. A sendEvent command executes early on the page that requests default personalization with renderDecisions not set (defaults to false). Propositions are fetched but not rendered.
  2. Later on the page, another sendEvent triggers with renderDecisions set to true but does not include any scopes or surfaces. Since there are no scopes or surfaces in this second call, nothing is rendered.

You can avoid this issue by either:

  • Setting renderDecisions to true on the first sendEvent call; or
  • Explicitly setting decisionScopes or surfaces on a subsequent sendEvent call when setting renderDecisions to true.

Render decisions using the Web SDK tag extension

The Web SDK tag extension equivalent of this property is the Render visual personalization decisions check box within the ‘Send event’ action.
