As well as in-feed posts, you can submit Reels, Carousels and Stories to Instagram Influencer Campaigns:
Post. Single image captioned in-feed post
Reel. Single captioned video posts up to 90 seconds
Carousel. Up to images or videos in a single captioned in-feed post
Story. Images and up to 15-second videos. Stories can be submitted as a single frame, or as a set of up to ten (10) frames. Stories can also be posted with link and engagement stickers (quiz, emoji slider, questions, poll, etc.)
Take a look at how these posts are displayed to brands here.
IMPORTANT: Always remember to publish in the format that was approved by the brand!
What happens if I posted the wrong format of content to my social media?
It's super important to ONLY submit the correct type of content to a campaign; and if your content is approved, you post the format that was approved for the campaign.
Why?
If you publish to IG in a different format, you will not receive your payment until the issue is resolved and this can take weeks. You'll have to resubmit with the correct submission type and the brand will have to approve it. Only then is your payout processed.
The most common examples of posting incorrectly?
Submitting a three-frame carousel in the app but then posting it separately i.e. two-picture carousel in your feed + one Story.
Submitting one static image in the app but then posting a video or Story on your socials
