With Agorapulse, you can schedule Instagram Story posts.
To publish a Story:
Open the composer and select an Instagram profile
Upload a video or image (for a list of recommended specifications please refer to this article)
In the Instagram options, select Story
You can choose a day & time to publish the post and schedule it, or choose to Publish now.
Please note that it is not possible to add text to a Story post, so the main content panel will not be available once the Story option is selected.
Things to note when publishing Story posts:
1. Due to API limitations, it is only possible to publish Instagram Stories with Business accounts.
You can find more information on this in Meta's Documentation here.
2. Due to API limitations, adding text effects or stickers to your Story posts is not available. To add these to your post, you may schedule your Story post from Agorapulse, and enable the Publish via mobile notification option.
3. Only 1 image or video can be published at a time as a Story. This is also an API limitation set by Instagram.
