Smarthings integration webhook update?

Some time ago I tried to install the Smartthings integration and it didn’t work, I gave up but have had another go. I add the integration and get this pop up

"SmartThings will be configured to send push updates to Home Assistant at:******d09b6fefeb4b099728f11*******92cd97ab1fbc8

If this is not correct, please update your configuration, restart Home Assistant, and try again."

However the webhook address is incorrect! How do I update it??
