title: Conversion Stats in Facebook's Ads API - cumulative or specific to time interval?
body: <p>For the <a href="https://developers.facebook.com/docs/reference/ads-api/conversionstatistics/" rel="nofollow">Conversion Stats</a> attribution values in the Ads API (ie, post_click_1d, post_click_7d, post_click_28d, post_imp_1d, post_imp_7d, post_imp_28d), are the values cumulative or are they capturing specific conversions relative to the time interval? </p>
  
  <p>If cumulative, do they reset per day?<br>
  Is there any difference between account, campaign and ad-level stats calls?</p>
