I've got JIRA on-call connected to New Relic by following this article: https://support.atlassian.com/jira-service-management-cloud/docs/integrate-with-new-relic-workflows/.
However, half of the fields don't show up in alerts created within JIRA (e.g. runbook URL, etc.) I've tried finding the reference documentation for the payload accepted by https://api.atlassian.com/jsm/ops/integration/v1/json/integrations/webhooks/newrelicv2 endpoint, but with no luck. Is it documented somewhere?
