LeadConnector is deprecating API key authentication and upgrading to OAuth on Zapier. If you have active LeadConnector app connections on version 3.0.4, you must reconnect before November 15, 2026. If your connections are not reconnected before then, your Zaps will be deactivated until you re-authenticate.
Replace your credential
- Go to the App Connections page.
- Filter for LeadConnector connections.
- Find any connections labeled version 3.0.4.
- Next to the connection, click the menu icon, then select Replace Credential.
- A pop-up window will appear. Follow the instructions to reconnect your LeadConnector account using the new OAuth authentication flow.
- Repeat for each version 3.0.4 connection.
Once you replace a connection, all Zaps using that connection are automatically updated. You do not need to edit any individual Zaps.
NoteYou only need to replace connections on version 3.0.4 of LeadConnector.
Common questions
No. Replacing a connection updates all Zaps that use it in one step. After reconnecting, monitor your Zaps in the following days to confirm they work as expected.
If you do not replace your connection before November 15, 2026, your Zaps will be deactivated. You can still replace the connection after November 15, 2026 to restore them.
Version 3.0.3 had a small bug that Zapier resolved in 3.0.4. If you already reconnected your 3.0.3 connections, you do not need to take further action. If you did not reconnect your 3.0.3 connections, you still need to reconnect your 3.0.4 connections. Without reconnection, your Zaps will stop working.
Yes. Version 3.0.4 supports your existing API key authentication until you reconnect. Once you reconnect, your connection upgrades to OAuth v2 authentication and remains on 3.0.4. You do not need to take further action to keep your Zaps running.
No. Version 2.0.4 connections already use OAuth v2 authentication and are compatible with LeadConnector's changes. All Zaps using 2.0.4 app connections will continue working after November 15, 2026.
