What This Skill Does

The PostFast skill provides a robust interface for automating social media management across nine major platforms: TikTok, Instagram, Facebook, X (Twitter), YouTube, LinkedIn, Threads, Bluesky, and Pinterest. By leveraging the PostFast SaaS API, this skill allows users to schedule posts, manage media uploads, and execute cross-platform content strategies directly through their OpenClaw agent. It simplifies the complex API requirements of social platforms into a unified workflow, enabling bulk scheduling and streamlined media handling.

Installation

To integrate this skill, use the following command in your terminal: clawhub install openclaw/skills/skills/peturgeorgievv/postfast

After installation, ensure you have registered at PostFast to obtain your API key. Set this as an environment variable in your session: export POSTFAST_API_KEY="your-api-key"

Use Cases

Campaign Synchronization: Automatically post the same announcement across LinkedIn, X, and Facebook at a synchronized time.
Content Pipeline: Schedule daily updates for multiple platforms weeks in advance without manual intervention.
Media-Rich Posting: Automate the upload of images and videos using the skill's signed S3 upload workflow.
Account Management: Quickly audit connected social profiles to ensure all organizational accounts are linked correctly.
Automated Workflow: Integrate with other OpenClaw skills to create a 'set-and-forget' social media engine.

Example Prompts

"List all my connected social media accounts so I can see which ones are ready for scheduling."
"Schedule a post for tomorrow at 10 AM on LinkedIn and Twitter with the text: 'Big news coming soon! Stay tuned.'"
"Upload my new promotional video and schedule it to go live on Instagram and TikTok on June 15th at 5 PM."

Tips & Limitations

Always verify IDs: Before scheduling, call the my-social-accounts endpoint to confirm the socialMediaId for each platform.
Media Constraints: Ensure your file uploads follow the 3-step signed URL flow to avoid failed requests. Large videos may require longer processing times.
Platform Specifics: While the API is unified, remember that different platforms have unique content constraints (e.g., character limits on X versus aspect ratios on TikTok). Use the controls object to apply platform-specific settings for optimal results.
