You can use many 3rd party library for HTTP request such as axios, fetch even XMLHttpRequest as you want to access core web API. You can use the following approaches it doesn't matter what's your endpoint.

 fetch('https://jsonplaceholder.typicode.com/posts/1', {
         method: 'GET'
      })
      .then((response) => response.json())
      .then((responseJson) => {
         console.log(responseJson);
         this.setState({
            data: responseJson
         })
      })
      .catch((error) => {
         console.error(error);
      }); 

using XMLHttpRequest

var xhr = new XMLHttpRequest()
    xhr.addEventListener('load', () => {
      console.log(xhr.responseText)
    })
    xhr.open('GET', 'https://dog.ceo/api/breeds/list/all')
    xhr.send()

using axios

axios.get('/user?ID=12345')
  .then(function (response) {
    console.log(response);
  })
  .catch(function (error) {
    console.log(error);
  })
  .finally(function () {
  });
