HTTP API Reference

Use the following guidelines for the Grafana OnCall API.

Authentication

To authorize, use the Authorization header:

# With shell, you can just pass the correct header with each request
curl "api_endpoint_here" --header "Authorization: "api_key_here""

Grafana OnCall uses API keys to allow access to the API. You can request a new OnCall API key in OnCall -> Settings page.

An API key is specific to a user and a Grafana stack. If you want to switch to a different stack configuration, request a different API key.

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.

Parameter	Meaning
`count`	The total number of items. It can be `0` if a request does not return any data.
`next`	A link to the next page. It can be `null` if the next page does not contain any data.
`previous`	A link to the previous page. It can be `null` if the previous page does not contain any data.
`results`	The data list. Can be `[]` if a request does not return any data.

Rate Limits

Grafana OnCall provides rate limits to ensure alert group notifications will be delivered to your Slack workspace even when some integrations produce a large number of alerts.
