# How Are the Publisher and Quick Action APIs Different?

The user interface in your org can dictate which development tools you can use to interact with actions. In Salesforce Classic, you use the Salesforce Classic Publisher JavaScript APIs with Visualforce components to interact with actions. In Lightning Experience, you use the `lightning:quickActionAPI` component to call the Lightning Quick Action JavaScript APIs to interact with actions.

## Implementation

**Salesforce Classic Publisher JavaScript APIs**

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

```xml
<script
  type='text/javascript'
  src='/canvas/sdk/js/43.0/publisher.js'/>
```

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

```javascript
Sfdc.canvas.publisher.selectAction({...})
```

**Lightning Quick Action JavaScript APIs**

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

```html
<aura:component implements="flexipage:availableForRecordHome" description="My Aura component">
  <lightning:quickActionAPI aura:id="quickActionAPI" />
</aura:component>
```

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

## Supported Actions, Apps, and Pages

## Lightning Experience and Salesforce Classic Support

**Salesforce Classic Publisher JavaScript APIs**

Works in Salesforce Classic and Lightning Experience. Starting with API version 43.0 of the Salesforce Classic JavaScript Publisher API, the methods used in Visualforce components and pages work in Lightning Experience. Just point to the latest version of the Publisher API script in your Visualforce pages.

```html
<script src="/canvas/sdk/js/43.0/publisher.js" type="text/javascript"></script>
```

The `portalPostFields` input value is not supported in Lightning Experience.

**Lightning Quick Action JavaScript APIs**

Works only in Lightning Experience. Before implementing, review the [Quick Action API Considerations](https://developer.salesforce.com/docs/platform/case-feed-dev-guide/quickactions/quickaction-api-considerations.md).
