Upload Media

Upload is Now Optional

You no longer need to upload media to Blotato before publishing. You can pass any publicly accessible image/video URL directly into the mediaUrls parameter in the Publish node. Blotato handles the media transfer automatically.

The Upload Media endpoint is still available if you prefer to use it, or if you need to host media on Blotato's servers.

Using Google Drive as a Media Source

Google Drive share links open a viewer page, not a direct file. Blotato needs a direct file URL to fetch and read media.

Set sharing permissions

For automation workflows (n8n, Make.com), set the entire Google Drive folder to "Anyone with the link" as Viewer. All files inside that folder inherit the same permission, so you do not need to set permissions on each file individually.

For one-off uploads, set the individual file to "Anyone with the link" as Viewer.

Use the direct download URL format

For files under 100MB, replace the standard share link with this format:

https://drive.usercontent.google.com/download?id={FILE_ID}&export=download&confirm=t

Replace {FILE_ID} with the ID from your share link. For example, if your share link is:

https://drive.google.com/file/d/1aBcDeFgHiJkLmNoPqRsTuVwXyZ/view

The file ID is 1aBcDeFgHiJkLmNoPqRsTuVwXyZ, so the direct URL is:

https://drive.usercontent.google.com/download?id=1aBcDeFgHiJkLmNoPqRsTuVwXyZ&export=download&confirm=t

Make sure the file is shared with "Anyone with the link" as Viewer.

Seeing error "Google Drive can't scan this file for viruses"?

This is the most common issue when using Google Drive. For large videos (100MB+), Google Drive shows a virus-scan popup that blocks Blotato from accessing the file.

For large files, use Dropbox, AWS S3, or Google Cloud Storage instead. These services provide direct download URLs without the virus-scan popup.
