Tips & Tricks
- Perplexity API account must have billing funded
- HeyGen API requires paid plan
- Make sure you copied your avatar ID correctly (not the group avatar ID)
- If your script is long, it takes more time for your video to finish
- While testing:
- Enable only 1 social platform and deactivate the rest
- Update AI writer prompt to return a 5-second script instead of 30 seconds to reduce processing time
- Go to HeyGen and check that your avatar video is being processed
- After the workflow finishes, check your social media account for the final post
- If successful, enable another social media node and continue testing
