Rich Publisher Apps platform

The Rich Publisher Apps platform gives you all the necessary tools for creating and integrating interactive apps into your feed’s publisher.

There are three ways to add a Rich Publisher App to your community.

1. Get it from AppExchange.

2. Build a custom app in your org.

3. Port an app through change sets or packages.

Creating Rich Publisher App:

1. Create the below Lightning Components.

Composer Component:

<aura:component implements="lightning:availableForChatterExtensionComposer">
    <aura:attribute name="options" type="List" default="[
    {'label': 'Thank You', 'value': 'Thank You'},
    {'label': 'Amazing Work', 'value': 'Amazing Work'}
    <aura:attribute name="selectedVal" type="String"/>
    <lightning:radioGroup label="Radio Button Group"
                          options="{! v.options }"
                          value="{! v.selectedVal }"

Composer Component Contrller:

appreciate: function(cmp, event, helper) {
        var compEvent = cmp.getEvent("sendChatterExtensionPayload");
        var selectedValObj = {value : cmp.get("v.selectedVal")};
