iNewsletter can automatically post a news feed item into Compass, with a link to your newsletter, when you publish a newsletter. Unfortunately Compass don't provide us with a way of sending a push notification when the news feed item is posted, however once you have published the newsletter in iNewsletter you can edit the news feed post in Compass and press the Save & Send Communications button in Compass to send a push notification.
To setup the integration, or change the user who the news feed item appears from:
Login to Compass as the user the news feed item should appear from
Click the Cogwheel icon in the top right corner and choose Administration Tools (if Administration Tools isn't in the menu, ensure the user is a member of the CompassSponsors group)
Choose Client Manager
Click Register Client and choose Register iNewsletter Client
Fill out audience details, we recommend staff and students. Give the client a name and choose Register
Take note of the newly generated Client ID
Now you need to add/update the Integration in iNewsletter:
On the Dashboard for the Publication you want to setup the integration for and go to Settings > Integrations
Next to Compass click the + icon or the pencil icon to add/edit the integration
In the popup window that appears, add or update your compass domain name and the Client ID you generated through Compass
Click Save & Close
You can also delete the Compass integration by clicking the Trash icon.
When you go to publish your next newsletter, you can click the Switch icon next to Send to Compass to enable publishing to Compass. You can also click the Cogwheel button to change the text that will be posted to Facebook.
