If you're seeing an invalid_grant error when trying to sync BigQuery data with Easy App Reports—especially after the first day of setup—you’re not alone. This issue is often caused by a Google Workspace reauthentication policy that forces the integration to expire every 16 hours by default.
The good news: this behavior can be fixed with a quick update in your Google Workspace admin settings.
🧩 What's Causing the Problem?
Google Workspace enforces a Reauthentication Policy for third-party apps. The default setting is:
Require reauthentication every 16 hours
This means that even if your BigQuery connection was working yesterday, it may be disconnected today unless you reauthenticate manually.
✅ Two Ways to Solve It
To keep your Easy App Reports integration with BigQuery stable, you can ask your Google Workspace admin to take one of the following actions:
Option 1: Exempt Easy App Reports as a Trusted App (Recommended)
This keeps reauthentication enabled for other apps, but makes an exception for Easy App Reports. Step-by-step instructions:
Go to your Google Admin Console;
In the left-hand menu, navigate to:
Security>Overview>Reauthentication SettingsSet the policy to: Exempt trusted apps
In the left-hand menu, click on:
Security>Access and data control>API controlsClick "Manage Third-Party App Access";
In the search box, Search for "Easy App Reports";
Click Select, then choose "Trusted" as the access level;
Save changes.
Now, Easy App Reports will be trusted and won’t require reauthentication unless you change the policy again.
Option 2: Set Reauthentication Policy to “Never Require Reauthentication”
This disables reauthentication for all third-party apps—only recommended if you trust your entire app ecosystem.
Step-by-step instructions:
Go to your Google Admin Console
In the left-hand menu, navigate to:
Security>Overview>Reauthentication SettingsChoose the appropriate organizational unit (OU)
Set the policy to: Never require reauthentication
Click Save
This will stop Google from invalidating third-party app tokens, including Easy App Reports.
🧪 How to Confirm It’s Working
After applying either fix, reconnect your BigQuery integration inside Easy App Reports (if needed)
Wait 24 hours — if the sync continues without error, the issue is resolved
