+# Credentials Auto-Configured from Grafana Cloud
+
+This example shows how to auto-configure the external services using a single token from an API call to Grafana Cloud.  The token must have `metrics:write`, `logs:write`, `traces:write`, `profiles:write` and `stacks:read` permissions. Credit [theSuess](https://github.com/theSuess) for providing the original [example](https://github.com/grafana/agent-modules/blob/main/modules/grafana-cloud/autoconfigure/module.river).
