Opsgenie

To be able to send notifications with argocd-notifications you have to create an API Integration inside your Opsgenie Team.

Login to Opsgenie at https://app.opsgenie.com or https://app.eu.opsgenie.com (if you have an account in the European Union).
Make sure you already have a team; if not, follow this guide: https://docs.opsgenie.com/docs/teams.
Click "Teams" in the Menu on the left.
Select the team that you want to notify.
In the team's configuration menu, select "Integrations".
Click "Add Integration" in the top right corner.
Select "API" integration.
Give your integration a name, copy the "API key", and save it somewhere for later.
Click "Edit" in the integration settings.
Make sure the checkbox for "Create and Update Access" is selected; disable the other checkboxes to remove unnecessary permissions.
Click "Save" at the bottom.
Click "Turn on integration" in the top right corner.
Check your browser for the correct server apiURL. If it is "app.opsgenie.com", then use the US/international API URL api.opsgenie.com; otherwise, use api.eu.opsgenie.com (European API).
You are finished with configuring Opsgenie. Now you need to configure argocd-notifications. Use the apiUrl, the team name, and the apiKey to configure the Opsgenie integration in the argocd-notifications-secret secret.
You can find the example argocd-notifications-cm configuration below.
