Using Webhooks

[mazarian]

Hi all! Really loving Uptime Kuma and wanted to know if anyone has tips on how to setup webhooks in there. I am running a separate Apprise API docker container on another machine (secured via Nginx and ACLs) and am thinking the only way I could pass notifications off is by using the webhook notification option in Uptime Kuma. There isn't much documentation on how to format the webhook and I was curious if anyone can offer some help.

For reference, I'm able to fire off notifications using the curl command like this:

curl -X POST -d '{"urls": "gchat://xxx/yyy/zzz", "body":"test message"}' -H "Content-Type: application/json" https://user:password@domain.tld/notify

OR

curl -X POST -d 'urls=gchat://xxx/yyy/zzz&body=test message' https://user:password@domain.tld/notify

@mazarian From what I can tell from https://github.com/louislam/uptime-kuma/blob/0dbecca10f5aaf53795f9f7a9568717372b9fcec/server/notification.js#L53, you just put the URL. The body of the message is always:

                {
                    heartbeat: heartbeatJSON,
                    monitor: monitorJSON,
                    msg,
                };

@girish Thank you! Sadly, without the ability to pass other content in JSON, I won't be able to use a remote Apprise instance with Uptime Kuma.

Nice I am trying uptime via webhook to n8n to rocket.chat. In principle, it works. The next invested hour will be about the payload.

@luckow that's what I did (ish)! Uptime Kuma notifications => n8n webhook => Matrix notification.

@thetomester13 cool. That's what "worked" for me.

"Problem": the workflow sends PAYLOAD ??? into the rocket.chat channel. I need to read the n8n docs to solve this. But every time I click the test button in uptime, I get the message in rocket.chat. MVP done

@luckow for reference, this is the Expression I have in my 'text' field:
{{JSON.stringify($json["body"])}}
I output the entire JSON body stringified because I use this webhook for multiple incoming notifications and they contain different payloads. But you can try and extrapolate from here by bringing in just the fields you need, i.e msg, monitor, etc.
