To pull in data from your Google account, go to Cost settings > Google Ads > Connect. You will be required to log into Google account and grant TrueProfit permission to access your Google ad campaigns. Choose Allow.
After that you'll be redirected to TrueProfit dashboard. You can then choose the ad account(s) relating to your store, then click Synchronize.
Integration Exchange Rate
If your Shopify store and Google Ads account use different currency, you can handle by setting an exchange rate.
Eg. If USD is your store's currency and EUR is your Google Ads account's currency, then US$1 is equivalent to 0.9 Google Ads currency units.
If you use the same currency across all platforms, leave the rate at 1.
