How Are the Publisher and Quick Action APIs Different?

To implement, load the publisher script in your Visualforce page or component. For example:

1<script 
2  type='text/javascript' 
3  src='/canvas/sdk/js/43.0/publisher.js'/>

Then you can reference the Publisher APIs through the Sfdc.canvas.publisher object. For example:

1Sfdc.canvas.publisher.selectAction({...})

To implement, use the component lightning:quickActionAPI in your custom Lightning component. For example:

1<aura:component 
2  implements="flexipage:availableForRecordHome" 
3  description="My lightning component">
4      <lightning:quickActionAPI 
5        aura:id="quickActionAPI" />
6</aura:component>

Then you can reference the Quick Action APIs in your controller code.
