I am looking to identify how the body looks for following request.

This is existing code which sends a post call to another client and also redirects to that client.

When normally making a post call, I am expecting the body to look something like this.

{
    someKey: 'some value'
}

But in this case, only the value is being set. What is the key here?

//Just from a normal js file. 
export const postData = (myRef, token, link) => {

  // question is on this line. Just setting a value. What is the key for the post body?
  myRef.current.children[0].value = token;
  myRef.current.action = link;
  myRef.current.submit();
};

This is the component where on click we call above function where we post and redirect to link.

const AComponent = () => {
  const myRef = React.useRef();
  const submit = () => {
    postData(myRef, 'some long token', 'www.google.com');
  };

  return (
      {/* Button is just another component that acts like a normal html button with some styling*/}
    <Button onClick={submit}>
      Click Me!
    </Button>
  );
};

export default AComponent;
