You can get the Webhook URL by clicking the channel name where you want the notifications to appear in the Hangouts Chat UI:
Choosing the "Configure webhooks" option presents a popup that allows you to create a new webhook. You can enter Honeybadger for the name, and saving the webhook generates the webhook URL:
Choose the Copy icon to copy the URL to your clipboard, then enter that url in channel settings in the Honeybadger UI.
That's it! You can test the integration by clicking "Test". Otherwise, just save it and you're ready to go.
If you'd like to install our chat bot in Google Hangouts Chat, search for "Honeybadger" in the "Find people, rooms, bots" search box in the Chat UI. Adding our bot will in Chat will prompt you to authorize the bot's access to your Honeybadger account. Once you do that, you'll be able to work with your Honeybadger data from within Chat.
