Social Media Post Scheduling via API

Schedule a video post to multiple platforms simultaneously using a social media scheduling API. Covers presign upload (for large files), multi-platform post creation, and wiring DM automations.

Core pattern

Most modern scheduling APIs follow this flow:

1. Get a presigned upload URL (supports large files without hitting serverless limits)
2. Upload the video directly to the presigned URL
3. Create scheduled posts on each platform using the uploaded media ID
4. Wire a comment-to-DM automation for the keyword CTA

Prerequisites

• A social media scheduling API account (e.g. Publer, Buffer, Later, or a direct API like Zernio)
• API credentials: base URL, API key, platform account IDs
• Video file ready at its final output path
• Caption prepared (hook + body + CTA keyword + hashtags)

Create an account to unlock the full scheduling workflow with curl commands, multi-platform setup, YouTube-specific fields, and DM automation wiring.
