OnCall API Reference

Use the following guidelines for the OnCall API in Grafana IRM.

Authentication

Note

OnCall API keys are being deprecated. While existing tokens will continue to work, we recommend using Grafana Cloud service account tokens for all new API authentication.

You can authenticate to the OnCall API using either a legacy OnCall API key or a Grafana Cloud service account token.

To access your OnCall API endpoint, go to IRM > Settings > Admin & API. For details, refer to the IRM settings documentation.

Service accounts allow you to assign explicit permissions to each token, and to revoke or rotate them as needed.

To authenticate with a service account token:

  • Add the Authorization header with your service account token.
  • Include the X-Grafana-URL header to specify your Grafana Cloud stack.
shell 
curl "https://your-stack.grafana.net/api/oncall/..." \
  --header "Authorization: <service account token>" \
  --header "X-Grafana-URL: https://your-stack.grafana.net"

For more information, refer to the Service account tokens documentation.

Authenticate using a legacy OnCall API key (deprecated)

You can still use an existing OnCall API key to authenticate requests. However, this method is deprecated and may be removed in the future.

shell 
curl "https://your-oncall-endpoint/api/..." \
  --header "Authorization: <oncall-api-key>"

Note

OnCall API tokens are user-specific - each token is only visible to the user who created it. Other users cannot view or manage tokens they did not create themselves.

Pagination

List endpoints such as List Integrations or List Alert Groups return multiple objects.

The OnCall API returns them in pages. Note that the page size may vary.

ParameterMeaning
countThe total number of items. It can be 0 if a request does not return any data.
nextA link to the next page. It can be null if the next page does not contain any data.
previousA link to the previous page. It can be null if the previous page does not contain any data.
resultsThe data list. Can be [] if a request does not return any data.

Rate Limits

Rate limits ensure alert group notifications are delivered to your Slack workspace even when some integrations produce a large number of alerts.
