# bing_create_ad_extension

> Create one ad extension (asset) in the account library: sitelink, callout, structured snippet, image, call, price, promotion, logo and other native types.

[Documentation](https://www.getmcpads.com/docs) / [Sources](https://www.getmcpads.com/docs/sources) / [Microsoft Advertising](https://www.getmcpads.com/docs/sources/bing-ads)

Create one ad extension (asset) in the account library: sitelink, callout, structured snippet, image, call, price, promotion, logo and other native types. It serves only once attached with bing_associate_ad_extension, under that entity's own status. Preview by default.

> **Note** Connect through Microsoft, then explicitly select the advertising accounts your assistant may access. Reads are available on Free; writes require an eligible paid plan.

> **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.
