When you use apps with Messenger, you can let the apps know who you're replying to so that the apps can create personalized GIFs, videos, photos, stickers and more for you to send to them.
Keep in mind that you can only personalize a reply if both you and the person you're talking to have logged into the app with Facebook.
Apps are required to follow Facebook's Platform Policy. If you think an app you're using doesn't follow this policy, you can report the app.
