Gmail connection blocked by Google
If Google displays “This app is blocked” while connecting Gmail, capture the exact message and identify the account you are trying to connect.
Start with the built-in Gmail connection
In Jet Admin, open Data → Add Resource.
Select Gmail.
Sign in to the Google account whose mailbox you want to connect.
Review the requested access and complete the connection if Google permits it.
This is the built-in connection flow. If you are following instructions for a custom OAuth client and are being asked for a redirect URI, first check whether the Gmail integration meets your task.
Google blocks authorization
A blocked authorization is different from an incorrect Jet Admin password. If this is a managed Google Workspace account, ask its administrator to check whether an organizational policy is involved.
If the block persists, contact Jet Admin support with:
The app URL and exact Google error.
Whether this is a personal or managed Workspace account.
Whether the Gmail mailbox is different from the account used to sign in to Jet Admin.
The time of the attempt and a screenshot with sensitive details removed.
The error alone does not establish whether the cause is an organization policy or an integration issue. Do not bypass the block or create a replacement OAuth configuration without confirming the cause.
Verify the connection
Once authorization succeeds, confirm the intended Gmail resource appears and test a read operation before using it in an automation.
