Prerequisites

- Chatter must be enabled on the CTA at either the Account or Customer level. To verify this, navigate to Administration > Workflow > Calls to Action.
- You will also need the necessary SFDC permissions to create a new VisualForce page and a new C360 section
New VisualForce Page

Use the following code when making the VisualForce page:
<apex:page showHeader="false" sideBar="false" > <style> body{padding: 15px;} </style> <chatter:feed entityId="{!$CurrentPage.parameters.cid}"/> </apex:page>
Preview Page

After you've saved the VisualForce page, click the Preview button. A new page will display in a separate window. Copy the URL that's in the window.
In this example, the URL I have is https://c.na16.visual.force.com/apex/CS360_Chatter
Add C360 Section
Navigate to Administration > C360 Layouts > [click edit on the relevant layout] > drag and drop the Section/Embed Page option on the left over to the right.

- Click the configuration gear on the new section.
- Type: Choose Embed Page
- URL Box: Here is where you will input the URL we copied from the Preview section (https://c.na16.visual.force.com/apex/CS360_Chatter)
- Height: The recommended height is 400 pixels
- Parameter: Choose Parameter and if you are using Chatter at the Account Level use Account::Id as the parameter. If you're posting at the Customer level use the Customer::Id field as the parameter.
- Click Save.
- Back in the sections list, click the edit icon (pencil) to add the section name in Show Label, and confirm Show in has the 360 selected.
- Click Save.
