How to Retrieve More Keyword Ideas via Google Ads API than Shown in the UI?

[Jack Smith]

Hello Google Ads Support Team,

We have a question regarding the Keyword Ideas service in Google Ads API.
Our consultant mentioned that using the API should allow us to access more long-tail keyword ideas than what is visible in the Google Ads UI (Keyword Planner).

However, in our current tests, the results returned by the API (e.g., GenerateKeywordIdeas endpoint) are very similar to what we see in the UI, and the total number of keywords remains limited (around 2,000+). We were expecting a larger set of keyword suggestions through the API.

For your reference, our Google Ads account already has Standard Access permission, so this is not a permission-level issue.

Could you please clarify:

1. Is the Keyword Ideas API supposed to provide more keyword results than the UI?
2. Are there any account-level restrictions (e.g., spend, account history, permissions) that affect the number of keyword ideas returned by the API?
3. Is there a recommended way (e.g., pagination, different request parameters, or specific API methods) to retrieve a larger set of long-tail keywords?

We would greatly appreciate your guidance on how to fully leverage the API for broader keyword research.

Thank you for your support!

Best regards,
Jack
