Slow Post request in React Native

Question

I am making a post request in react-native using apisauce, but the request is too slow. The request takes around 1000ms in Postman, but is slower in react-native. How can I optimize this?

My sample response data is like

[
    {
      "email": "abc@gmail.com",
      "id": 2753,
      "phone_number": "",
      "user_name": "New client"
    },
    {
      "email": "cda@gmail.com",
      "id": 2754,
      "phone_number": "",
      "user_name": "New client"
    },
    {
      "email": "dsa@gmail.com",
      "id": 8868,
      "phone_number": "",
      "user_name": "Slow"
    }
  ]

And the program for post request is:

    const setConfigHeader = () =>
        api.setHeader(
          'Authorization',
          getState().login.data.access_token
            ? `Bearer ${getState().login.data.access_token}`
            : null,
        );
    
    const getAddressBookData = data =>
        api.post(globalConstants.user_address_book, data, setConfigHeader());
