+### Team based Logging to Langfuse
+
+**Example:**
+
+This config would send langfuse logs to 2 different langfuse projects, based on the team id 
+
+```yaml
+litellm_settings:
+  default_team_settings: 
+    - team_id: my-secret-project
+      success_callback: ["langfuse"]
+      langfuse_public_key: os.environ/LANGFUSE_PUB_KEY_1 # Project 1
+      langfuse_secret: os.environ/LANGFUSE_PRIVATE_KEY_1 # Project 1
+    - team_id: ishaans-secret-project
+      success_callback: ["langfuse"]
+      langfuse_public_key: os.environ/LANGFUSE_PUB_KEY_2 # Project 2
+      langfuse_secret: os.environ/LANGFUSE_SECRET_2 # Project 2
+```
+
+Now, when you [generate keys](./virtual_keys.md) for this team-id 
+
+```bash
+curl -X POST 'http://0.0.0.0:4000/key/generate' \
+-H 'Authorization: Bearer sk-1234' \
+-H 'Content-Type: application/json' \
+-d '{"team_id": "ishaans-secret-project"}'
+```
+
+All requests made with these keys will log data to their team-specific logging.
+
 ## Logging Proxy Input/Output - DataDog
 We will use the `--config` to set `litellm.success_callback = ["datadog"]` this will log all successfull LLM calls to DataDog
