Grafana OnCall HTTP API reference

HTTP API Reference

Use the following guidelines for the Grafana OnCall API.


To authorize, use the Authorization header:

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

Note that meowmeowmeow is a valid key for test purposes. Replace meowmeowmeow with your API key in production.

Grafana OnCall uses API keys to allow access to the API. You can request a new OnCall API key in the API section.

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


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.
