Hi,
Thank you for reaching out to the Google Ads API support team.
Please note that performance data isn’t available instantly, and some metrics are only updated once a day. Recent account data may not be reflected immediately.
In most cases, your account statistics (such as clicks, conversions, and impressions) are delayed by less than 3 hours. Conversions attributed using
attribution models other than “Last click” are typically delayed up to 15 hours.
For more information, you can refer to this help center article
