+
+:::info
+We want to learn how we can make the callbacks better! Meet the LiteLLM [founders](https://calendly.com/d/4mp-gd3-k5k/berriai-1-1-onboarding-litellm-hosted-version) or
+join our [discord](https://discord.gg/wuPM9dRgDw)
+::: 
+
+## Pre-Requisites
+Ensure you have run `pip install wandb` for this integration
+```shell
+pip install wandb litellm
+```
+
+## Quick Start
+Use just 2 lines of code, to instantly log your responses **across all providers** with Langfuse
+
+
+Get your Langfuse API Keys from https://cloud.langfuse.com/
+```python
+litellm.success_callback = ["wandb"]
+```
+```python
+# pip install langfuse 
+import litellm
+import os
+
+os.environ["WANDB_API_KEY"] = ""
+# LLM API Keys
+os.environ['OPENAI_API_KEY']=""
+
+# set langfuse as a callback, litellm will send the data to langfuse
+litellm.success_callback = ["wandb"] 
+ 
+# openai call
+response = litellm.completion(
+  model="gpt-3.5-turbo",
+  messages=[
+    {"role": "user", "content": "Hi 👋 - i'm openai"}
+  ]
+)
+```
