+
+The Fiddler receiver ingests metrics data from [Fiddler](https://docs.fiddler.ai/) and converts it into the OTLP metric format.
+
+> **Warning**  
+> This receiver is currently in development. Functionality and configuration options may change.
+
+## Configuration
+
+The following settings are required:
+- `endpoint`: The URL where Fiddler is deployed for your organization.
+- `token`: Your authorization token from the Fiddler Settings page under the Credentials tab.
+
+The following settings are optional:
+- `interval`: The interval at which metrics data is pulled from Fiddler (default: `30m`).
+
+### Example Configuration
+
+```yaml
+receivers:
+  fiddlerreceiver:
+    endpoint: https://api.fiddler.ai
+    token: "your_authorization_token"
+    interval: "30m"
+```
