Zulip supports integration with Crashlytics and can notify you about Crashlytics issues.

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

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

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!
