400 Bad Request - Insert Record

Hi, I have been trying to create a lead through API. Lead passes through successfully if I do not pass description in a payload. Or it passes if I remove \n from the description value. I looked at the API documentation and Description field accepts new line (\n). What am I doing wrong here?

Here is the request data: (This didnt go through)
"{\n\"data\": [\n{\n\"Company\": \"xxxxcompany\",\n\"First_Name\": \"Ashhad\",\n\"Last_Name\": \"Billi\",\n\"Email\": \"\",\n            \"Phone\": \"(647) 871-9067\",\n            \"Description\": \"Agent: Who is there?\nVisitor: hello\nVisitor: 6478719067\"\n}\n]\n}"

This works:
"{\n\"data\": [\n{\n\"Company\": \"xxxxcompany\",\n\"First_Name\": \"Ashhad\",\n\"Last_Name\": \"Billi\",\n\"Email\": \"\",\n            \"Phone\": \"(647) 871-9067\",\n            \"Description\": \"Agent: Who is there? Visitor: hello Visitor: 6478719067\"\n}\n]\n}"
