Adding music or links to Instagram Reels and Stories is not supported in Postpone or any other third-party scheduling tool.
Why music and links are not supported
Instagram's API does not expose music selection or link sticker functionality to third-party applications. This is a platform-level restriction that applies to all scheduling and social media management tools — it is not specific to Postpone.
Workaround: notification posting
You can still plan and time your Reels and Stories in advance while adding music or links yourself at posting time. The recommended approach is to use notification posting:
- Schedule your Reel or Story in Postpone as usual.
- When it's time to post, Postpone sends you a notification.
- Open Instagram from the notification and complete the post — including selecting your music track or adding a link sticker — before publishing.
This gives you the benefits of advance scheduling while keeping full control over features Instagram reserves for native posting.
