[Documentation](https://www.getmcpads.com/docs) / [Sources](https://www.getmcpads.com/docs/sources) / [Snapchat Ads](https://www.getmcpads.com/docs/sources/snapchat-ads)

Initialize a chunked video upload, up to 256 MiB across at most 32 parts of 8 MiB. Returns upload_id, add_path and finalize_path to use for subsequent calls. Preview unless confirm true.

> **Warning** This tool changes the account. It is absent from the tool list on the Free plan, and it previews by default: without `confirm: true` it describes the change and applies nothing.
