Hi Vasyl,
Thank you for reaching out to Google Ads API Forum.
Although it is normal in general to have multiple ad groups within a campaign, you also mentioned that you have thousands of products. Kindly note that limits are also taken into account in Google Ads. You may refer to this help page about Google Ads account limits.
You may also refer to this guide about Shopping Listing Groups.
I hope this answers your question. Let me know if you have follow up questions related to Google Ads API.
Regards,
