+
+Use this if you want to reject /chat/completion calls that have prompt injection attacks with [AporioAI](https://www.aporia.com/)

+#### Usage
+
+Step 1. Add env

+```yaml 
+litellm_settings:
+  callbacks: ["aporio_prompt_injection"]
+```
+
+That's it, start your proxy
+
+Test it with this request -> expect it to get rejected by LiteLLM Proxy
+
+```shell
+curl --location 'http://localhost:4000/chat/completions' \
