path variables in react api call

I have an API that responds to an API call like below in Postman:

The body is just

"username": "bobmarley"  

How can I replicate this in my React/Next project. Here is what I currently have:

export async function getUser(data) {

const response = await fetch(http://localhost:4000/users/:username, { method: 'POST', headers: {'Content-Type': 'application/json'}, body: JSON.stringify(data) }) var response_data = await response.json();

return(response_data); }

How can I pass these path variables like in Postman too?
