The SongSelect integration can be enabled by going to Service Planning from the left-hand menu and clicking on "Song Integrations" in the upper right-hand corner.
This can alternatively be enabled by going to the cog menu in the top header and then visiting the Integrations page.
Once the "Enable" button is clicked, a pop up will appear asking you to log into your SongSelect account. If you are already logged in, then the integration will be automatically enabled without needing to log in again. If the pop up does not appear, make sure any pop-up blockers for the site are disabled.
After enabling, integration options will appear. It's highly recommended to enable auto-reporting so that your song usage will be automatically reported to CCLI each week.
