Where to setup JSON body for alerting webhook

Grafana Alerting
,
1

Hi, I’m using grafana 8.5.2, self hosted, new alerting system, wanting to setup a webhook to send SMS via my provider (twilio) …

Alerting → Contact Points → New → Webook

… allows me to add the URL, METHOD, user, pass … all ok.

BUT, where is it possible to configure any additional JSON body data? twilio provides for setting the TO and FROM and BODY via JSON.

The docs (Contact points | Grafana documentation) list an example JSON body, can I configure to send some/all of that?

It seems like something that should be very obvious, but I just can’t seem to find it? I presume as soon as I hit “send”, I’ll find the answer :roll_eyes:

Is this a brand new instance? Are you using the legacy alerting system?

check out the new message templating docs:

Did you ever get to the bottom of this one?

Im actually testing it now - (With legacy alerting)
but according to the documentation - while you can’t modify the json body, you can add tags to it

So i want to use tags to specify the hook properties like
tagname: tagvalue
trigger: ssm
command: sudo service blabla restart

Have you figured it out how to do it? I need to send labels on the JSON but I can’t find how to do it

Starting with Grafana 12, webhook contact points support a custom payload, allowing you to define the entire JSON body that gets sent when an alert fires.

In earlier versions, only the title and message fields were customizable — full control over the JSON structure wasn’t available.

Here are a few templating examples that show how to include labels in the payload.
