If you agreed to usage rights for an Instagram Reel, you'll be asked to submit an Instagram partnership ad code. An Instagram partnership code is what allows your brand partner to run your video as an ad on Instagram. When you give your brand partner the partnership ad code for your Instagram post, they can enter it into their ads manager, load up some money, and get your video to appear in ad slots across Instagram. The video is still attributed to you, and has your handle—users tapping on it will be taken to your profile. It's a win-win situation: It's a great way to drive engagement for your video, and the brand also gets visibility for their brand.
