To view results and track conversions for your sponsored messages:

1. Go to Ads Manager.
2. Select the Messenger engagement column to view impressions, link clicks, replies, blocks and conversions for your sponsored messages.
• If you've set up pixel events, app events or offline conversions, those metrics will appear in the corresponding columns
