Create an alert on alertmanager using curl

Question

I came across this need and could not find a simple answer:

I have a Prometheus + Alertmanager setup and want to test the alertmanager third party integrations.

So I wanted to create a dummy alert without having to change rules on prometheus and etc.

How can I create a test alert on alertmanager?

Answer 1

In case someone else has the same need sometime, it can be achieved by a simple curl command like bellow

curl -w '\n' -i --user 'admin:admin' \
  --header 'Content-Type: application/json' \
  --data '[{"labels":{"alertname":"test_opsgenie", "team":"opsgenie"},"endsAt":"2023-03-21T00:10:53-03:00"}]' \
