# amazon_ads_upload_asset_bytes

> Upload supplied image/video bytes to the native S3 URL bound to the opaque uploadToken from prepare_asset_upload.

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

Upload supplied image/video bytes to the native S3 URL bound to the opaque uploadToken from prepare_asset_upload. No bearer credentials are sent to S3. Preview/confirmation binds the byte digest. Register the asset afterwards; this does not create an ad.

> **Note** Connect Amazon and explicitly select the profiles your assistant may access. Tested with an Amazon test account. Product, brand and format eligibility are enforced by Amazon; DSP and AMC are separate products.

> **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.
