If you don’t specify a timezone, Postly uses your Workspace timezone.
If no workspace timezone is set, Postly falls back to UTC.
🖼 Media URL Rules
✅ Works
- Direct files from public CDNs (
.jpg,.png,.gif,.webp,.mp4,.mov) - Standard YouTube links (
watch?v=…) - Standard Vimeo links
- Postly Cloud URLs (fastest, permanent)
Examples
https://cloud.postly.ai/media/banner.jpg
https://cloud.postly.ai/media/launch-video.mp4
https://www.youtube.com/watch?v=VIDEO_ID
https://vimeo.com/76979871
❌ Won’t Work (and Why)
| Example | Why It Fails |
|---|---|
youtube.com/shorts/... | Shorts = page link, not a real video file |
| Google Drive / iCloud links | Requires login. Not a direct public file |
| Dropbox preview URLs | HTML preview, not the file itself |
| Expiring signed URLs | They break before your publish time |
Base64 data:image/... | Unsupported in Bulk Post |
📝 CSV Examples
✅ Valid Rows
| text | platforms | due_date | image_url | video_url |

| Wikimedia JPG | 2025/10/27 22 | https://upload.wikimedia.org/wikipedia/commons/9/9a/Gull_portrait_ca_usa.jpg |
❌ Common Pitfalls

|---|---|---|---|---|---|
