New Relic can send messages to a Zulip stream for alerts and deploys.

First, create the stream you'd like to use for New Relic notifications, and subscribe all interested parties to this stream. We recommend the name newrelic.

Next, in your New Relic Account Settings page, click "Integrations", then "Alerting notifications". On the "Webhook" tab, enter the following webhook URL:

{{ external_api_uri_subdomain }}/v1/external/newrelic?api_key=abcdefgh&stream=newrelic

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

Congratulations! You're done!
Your New Relic events will appear in Zulip:
