Can't authenticate through AlertManager / Prometheus

[Tim Davis]

Hello Im trying to set up the integration with OpsGenie through AlertManager / Prometheus. I followed several examples on the web for configuration, but errors logs say "Authentication Failed" Is there anything else I need to add to Alertmanager Config?

unexpected status code 401: {\"message\":\"Could not authenticate\",

Here is a sample of my alertmanager config file

global:
  opsgenie_api_key: XXX
  opsgenie_api_url: 'https://api.opsgenie.com/'
route:
  group_by: ['alertname', 'cluster', 'service']
  group_wait: 30s
  group_interval: 5m
  repeat_interval: 3h
  receiver: opsgenie
  routes:
   - match:
     receiver: opsgenie
receivers:
 - name: 'opsgenie'
   opsgenie_configs:
    - send_resolved: true
      http_config: {}
      api_key: XXX
      api_url: https://api.opsgenie.com

Hi @Tim Davis ,

I believe we spoke yesterday around the same issue, and realized the 401 was due to the wrong API key being used in Alert Manager conf. file.
