📝 Describe your problem

I am trying to post an automated notification to Synology Chat using the Webhook notification type. Synology chat expects a payload querystring parameter formatted like this:

?payload= {"text": "Uptime Kuma alert: {{check.name}} is {{check.status}}"}

I got that format from asking ChatGPT. Not sure where it got the "{{check.name}}" format because it doesn't work. What gets posted to the chat channel on Synology Chat is:

So the integration is working but the variable names don't get translated by Uptime Kuma. Again, I don't know where ChatGPT got the syntax, since I can't find an example that uses that syntax.

So my question is, is there a correct syntax that can be put in the querystring that will translate those variables into the actual values or do I need to put in an enhancement request to either allow that functionality or to add a new Notification Type for Synology Chat?

Thanks in advance for your help!

I have created a docker container to take care of this integration.

will be nice once it's fully added natively into uptime-kuma :)

To correctly format the payload for the Synology Chat webhook notification, you should modify the "Request Body" section in your Uptime Kuma settings as follows:

• Set "Notification Type" to "Webhook."

• In the "Friendly Name" field, you can provide any name you prefer.

• In the "Post URL" field, make sure it follows this format: https://<DS_IP>/webapi/entry.cgi?api=SYNO.Chat.External&method=incoming&version=2&token=%22<YourToken>%22&

• For the "Request Body," choose "Custom Body" and set the payload as:

payload={"text": "{{ msg }}"}

Please note that it's essential to include & at the end of the "Post URL" after %22.

These settings should ensure that the payload is correctly formatted for Synology Chat.

My UptimeKuma says:

Error: Additional Headrers is not valid JSON :(

What did you put into the Additional Headrers field?

What did you put into the Additional Headrers field?

?payload= {"text": "Uptime Kuma alert: {{check.name}} is {{check.status}}"}

That is supposed to go into the Request Body>Custom Body field instead according to the post above
