Regarding Dynamic Keyword Insertion in Responsive search ads

[Nuthi Naresh]

Hi Team,

I hope you're doing well.

I’m reaching out to check if there is any way, via the Google Ads API or GAQL, to determine whether an ad has opted for Dynamic Keyword Insertion (DKI).

I understand that DKI typically appears in the ad text using the {Keyword:default} syntax. However, since the text fields (e.g., headlines, descriptions) are returned as arrays in responsive_search_ad objects, there doesn’t seem to be a direct way to filter or detect DKI usage programmatically.

Could you please confirm if:

1. There is any field or flag that identifies whether an ad is using DKI?
2. There’s any known best practice or recommended method to detect DKI ads efficiently through the API or GAQL?

Any guidance or reference documentation would be highly appreciated.
Thank you for your support!

Please find the screenshot here. If the ad text of a RSA contains "{" then we can say that ad is using DKI. This flower parentheses may present in any of the headline,description or path of the RSA.

How can we know without retrieving all the ads data?

Best regards,
