Meta Ads / API Reference
meta_ads_upload_video_file_bytes_to_meta
Raw-bytes-only video uploader. For normal chat upload requests, prefer meta_upload_ad_video because it accepts public URLs and source values. Use this only when you explicitly have raw video bytes or a data URI and want a video_id in the Meta video library. Pass file_bytes_base64 as raw base64 or data:video/mp4;base64,...; do not pass local file paths. account_id is the primary account parameter; video_base64 and ad_account_id are legacy aliases.
This is a write tool: it uploads video file bytes to meta in your Meta Ads account. Claude asks you to confirm before it runs.
