You can post, or schedule, an Instagram story right from your SND Dashboard!
Click the Create a Post button to open the Post Composer.
Click on the dropdown at the top to select an Instagram account(s).
Upload a vertical video (or create one in Video Studio). Select the toggle option to publish to Instagram Stories, or publish to Stories and your Feed. Instagram Stories support 1 image or video. Images must be less than 8mb. Videos must be less than 100MB and between 3 and 60 seconds long.
Once your media has successfully uploaded, you can click the blue Post Now button or schedule for later.
