Frequently Asked Questions
- What is a social media scheduler API?
- └A social media scheduler API is a REST interface that lets developers programmatically schedule posts to publish at a specific date and time across multiple social platforms. Zernio supports scheduling to 15 platforms with timezone control, recurring queues, and bulk upload.
- Can I schedule posts via both API and dashboard?
- └Yes. Zernio includes both a full REST API and a visual dashboard with a content calendar. Use the API for programmatic scheduling in your own app, or the dashboard for manual planning. Both are included on every plan.
- What happens if a scheduled post fails?
- └Zernio automatically retries up to 3 times with exponential backoff. If the post still fails (e.g., expired token), you're notified via webhook.
- Does Zernio support recurring post schedules?
- └Yes. The Queue feature lets you define weekly time slots (e.g., Monday 9 AM, Wednesday 2 PM). New posts auto-fill the next available slot without setting a specific date each time.
