The requirements Meta doesn't waive
Instagram's content publishing API works only with professional accounts (business or creator) linked to a Facebook Page. Personal accounts can't publish via API — any tool claiming otherwise is using methods that risk your account.
- ✓ One JPEG image or one video (published as a Reel) per post
- ✓ Captions up to 2,200 characters
- ✓ Meta caps API publishing at 50 posts per account per 24 hours
The container flow, handled for you
Like Threads, Instagram publishes in two steps: create a media container from a public image or video URL, wait for processing (videos take a moment), then publish. SparkSocialHq runs the flow end to end and polls video containers until they're ready — you just see 'published' with a link.
Instagram in your cross-posting routine
Because every Instagram post needs media, the composer's live validation reminds you the moment you select Instagram without an image or video attached. Your caption is trimmed to 2,200 characters automatically if needed — hashtags kept, since they still matter on Instagram.
