A connection is an authorized link between Zoho Flow and an app account. It enables your flows to read and write data on your behalf.
You can create connections for both built-in apps and custom apps (via Auth Profiles). All connections, including those created through Auth Profiles are listed here.
From the Connections page, you can:
Create a new connection
Share or unshare a connection with your organization
Test a connection to verify it is working
Reconnect a connection to fix issues or update permissions
Delete a connection permanently
Transfer ownership of a connection to another member
Note: Deleting a connection is permanent. Flows using it will fail after deletion. You can transfer up to 30 connections at a time.Transferring connections can be useful, and can keep your flows running uninterrupted, especially in scenarios such as:
When a member leaves your team or organization, and you need to stop using their credentials to maintain the connections used in your flows.
When a member no longer uses an app, and another member wants to use the app account using their own credentials.
When the app's licensing changes and access shifts to a different user.
A connection can be transferred only by that connection's owner, the organization owner, or the admins. To do so:
Navigate to Settings > Connections.
Select the connections you want to transfer using the selection check box, then click Transfer Ownership.
In the dialog box that follows, select the member you want to transfer the connection to and click Transfer.

If a connection has been transferred to you, log in to your Zoho Flow account and follow these steps:
After you reconfigure the connection, review every flow that uses it. Pay attention to:
Field mappings that reference account-specific values (e.g., project IDs, workspace selectors, channel names)
Trigger conditions that may filter on user-specific fields
Any custom function logic that depends on the previous owner's account

Important tips:
Only a connection owner/organization owner/admin can transfer or delete a connection.
Removing or deactivating a member from an organization without transferring their connections will disable any live flows using those connections, invalidate them, and delete any unused connections.
You can only transfer up to 30 connections at a time.
