Hi Pedro,
Thank you for reaching out to us. If you take a look at the Google Console you can see under APIs & Services the amount of calls, metric data, and quota limits you have for Google Ads API. You can also check in the UI by searching for "Conversions" to check if the conversions you've uploaded for your account have been processed. Let me know if you have further questions.
Thank you,
Bryan, Google Ads API Team
