What this operation supports in Pushbullet
Sends a file push -- attaching a file so it appears as a downloadable push on the recipient's connected devices.
Implementation details
Pushbullet's file pushes typically require uploading the file to get a hosted URL first, then sending the push referencing that uploaded file, rather than attaching raw file bytes directly in the push itself.
Operational considerations
Checking the file size against Pushbullet's upload limits before sending avoids a failed push for files that are too large.
Use cases
This endpoint enables file-based notifications and attachments in automations.
