Trigger /api/webhook with curl

[lukonjun]

Hi there, I would like to trigger the /api/webhook endpoint of the application set controller with curl or any other cli tool.
I following the documentation from here https://argocd-applicationset.readthedocs.io/en/stable/Generators-Git/ to build this curl command:

curl -X POST argocd-applicationset-controller:7000/api/webhook -H "Content-Type: application/json" -d '{"message":"lets trigger"}'
Unknown webhook event

When running curl however the logs of the application set controller show no extra syncing going on.

Any ideas?

ApplicationSet ignores events that don't look like git events.

argo-cd/applicationset/utils/webhook.go

Lines 110 to 117 in 14cdfc7

	case r.Header.Get("X-GitHub-Event") != "":
	payload, err = h.github.Parse(r, github.PushEvent, github.PullRequestEvent)
	case r.Header.Get("X-Gitlab-Event") != "":
	payload, err = h.gitlab.Parse(r, gitlab.PushEvents, gitlab.TagEvents)
	default:
	log.Debug("Ignoring unknown webhook event")
	http.Error(w, "Unknown webhook event", http.StatusBadRequest)
	return

Try setting one of those headers to push.

I imagine it's trying to parse the JSON as a github or gitlab webhook payload. I'd recommend testing with an example payload from your SCM of choice.

@lukonjun : As @crenshaw-dev mentioned u can try one of this json: https://github.com/argoproj/argo-cd/tree/master/applicationset/utils/testdata

@rishabh625: Url has gone, mind posting the example here?
New url as of 18th Aug 2023: https://github.com/argoproj/argo-cd/blob/master/applicationset/webhook/testdata/github-commit-event.json

I'm on version 2.8.6 and sending this:
curl -X POST -H 'Content-type: application/json' -H 'X-GitHub-Event:push' -d '{"ref": "","repository": {"html_url":"https://[email protected]/org/project/_git/repo"}}' localhost:8080/api/webhook

There is a successful "Received push event repo" log entry and by looking at the code this seems to be all that is needed, but for some reason, nothing happens. As far as I see it should refresh the appset and I'm 100% sure that appset has the same URL. Am I missing something?

It's also strange that even if I manually refresh an appset it doesn't get the latest changes in the repo, but I suppose this is offtopic.

Just go through this matter recently, my case is that I wanna trigger the Applicationset generation manually from Github Workflow instead of implementing Github Webhook.
I found out the below curl command along with the payload block working exactly as expected. Hope this be useful for anyone dealing with this same topic:

curl -X POST -H "Content-Type: application/json" \
-H "X-Github-Event:pull_request" \
-d '{
  "action": "actiontype",
  "repository": {
    "name": "myrepository",
    "owner": {
      "login": "myorg"
    },
    "url": "https://api.github.com/repos/myorg/myrepository"
  }
}' \
