# GAM - Settings & Limitations

### **Settings needed**

- Complete all steps explained in our article ["How to implement Google AdX & OpenBidding in Pubstack?"](https://help.pubstack.io/how-to-implement-google-adx-openbidding-in-pubstack?hsLang=en)
- Contact your account manager. They’ll activate the dashboard for you.

### **Limitations**

- There may be some data discrepancy between **Pubstack Real Time vs Pubstack GAM.** Examples: 
    - **Pubstack Overview,** data retrieve directly from the client-side VS **Pubstack GAM**, data retrieve directly from GAM server
    - Inventory not mapped. For example, GAM adUnits that are not in Prebid.
    - Prebid impressions not going through GAM (Consentless and Ad-blocked traffic)
    - Instream video
- We have **one day of delay** due to how GAM works.
- As usual, we only have 30 days of data. Due to the limitation above, the data from today is not available.
- The data is only available at **a daily level.** And not hourly, due to inherent GAM limitations
- It may have some data discrepancy between **Pubstack Real Time vs Pubstack GAM**
