# What this PR does
Allows public OnCall API to use Grafana service accounts for
authorization. In cloud requests using a Grafana service account token
also needs to provide headers for `X-Grafana-Org-Slug` and
`X-Grafana-Instance-Slug`
This is **alpha** functionality, it may break or be removed in the
future. Going to use this on one endpoint (resolution notes) before we
consider the implications across all of public API.
