Next, on your {{ settings_html|safe }}, create a bot for {{ integration_display_name }}. Make sure that you select Incoming webhook as the Bot type:

The API key for an incoming webhook bot cannot be used to read messages out of Zulip. Thus, using an incoming webhook bot lowers the security risk of exposing the bot's API key to a third-party service.

Construct the URL for the {{ integration_display_name }} bot using the bot's API key and the desired stream name:

{!webhook-url.md!}

Modify the parameters of the URL above, where api_key is the API key of your Zulip bot, and stream is the stream name you want the notifications sent to.
