An operation representing creation of a new callout. Calling any method ([getErrors](https://developers.google.com/google-ads/scripts/docs/reference/adsapp/adsapp_calloutoperation#getErrors), [getResult](https://developers.google.com/google-ads/scripts/docs/reference/adsapp/adsapp_calloutoperation#getResult), or [isSuccessful](https://developers.google.com/google-ads/scripts/docs/reference/adsapp/adsapp_calloutoperation#isSuccessful)) will cause the operation to execute and create the callout. To make the script more efficient, it's recommended that you store the operations in an array and only call these methods once you've constructed all the operations you want.
