Our company blocks all native messaging by default in Chrome and Edge by setting the registry key:

`Software\Policies\Google\Chrome\NativeMessagingBlocklist\1 = '*'`

(See [Chrome Enterprise Policy List & Management | Documentation](https://chromeenterprise.google/policies/#NativeMessagingBlocklist) )

When attempting to use HttpWatch this causes the following error:

 ![1_error_message](https://forum.httpwatch.com/uploads/default/original/1X/04cfcbb3d97d2b5513533e0d1262578e646181ca.png)

What value should I add to the [NativeMessagingAllowlist](https://chromeenterprise.google/policies/#NativeMessagingAllowlist) to enable HttpWatch for Native Messaging?

For Chrome add the value com.httpwatch.chrome.extension to [NativeMessagingAllowlist](https://chromeenterprise.google/policies/#NativeMessagingAllowlist) , e.g.

`Software\Policies\Google\Chrome\NativeMessagingAllowlist\1 = com.httpwatch.chrome.extension`

and for Edge use com.httpwatch.edge.extension (see [Edge NativeMessaging Policies](https://docs.microsoft.com/en-us/deployedge/microsoft-edge-policies#native-messaging)):

`SOFTWARE\Policies\Microsoft\Edge\NativeMessagingAllowlist\1 = com.httpwatch.edge.extension`
