+## Obtaining Last9 OpenTelemetry Endpoint and Basic Auth Header
+
+[Click here](https://app.last9.io/integrations?category=all&integration=OpenTelemetry) to visit the Last9 OpenTelemetry integration page.
+
+<Frame>
+    <img src="/backends/images/last9.png" alt="OpenTelemetry integration in Last9" />

+
+## Configuring Last9 Backend
+
+- **Endpoint** - Last9 OpenTelemetry Endpoint obtained in above step.
+- **Authorization Header**: Last9 OpenTelemetry Basic Auth Header obtained in above step.
+
+## Adding a Destination to Odigos
+
+Odigos makes it simple to add and configure destinations, allowing you to select the specific signals [traces/logs/metrics] that you want to send to each destination. There are two primary methods for configuring destinations in Odigos:
+
+1. **Using the UI**
+   To add a destination via the UI, follow these steps:
+   - Use the Odigos CLI to access the UI: [Odigos UI](https://docs.odigos.io/cli/odigos_ui)
+   ```bash
+   odigos ui
+    ```
+- In the left sidebar, navigate to the `Destination` page.
+
+- Click `Add New Destination`
+
+- Select `Last9` and follow the on-screen instructions.
+
+
+
+2. **Using kubernetes manifests**
+
+Save the YAML below to a file (e.g., `destination.yaml`) and apply it using `kubectl`:
+
+```bash
+kubectl apply -f destination.yaml
+```
+
+
+```yaml
+apiVersion: odigos.io/v1alpha1
+kind: Destination
+metadata:
+  name: last9-example
+  namespace: odigos-system
+spec:
+  data:
+    LAST9_OTLP_ENDPOINT: <Last9 OpenTelemetry Endpoint>
+  destinationName: last9
+  secretRef:
+    name: last9-secret
+  signals:
+  - TRACES
+  - METRICS
+  - LOGS
+  type: last9
+

+  LAST9_OTLP_BASIC_AUTH_HEADER: <base64 Basic Auth Header>
