Best Practices

• Ensure the video file is in a supported format (MP4).
• The media URL must be publicly accessible or hosted on a compatible server.
• If you don’t have a shareable media URL, upload your media to our cloud and use the generated URL to send it.
• Optimize video size for fast and smooth delivery.
