Need help with integrating an API service. How do you usually do that? I'm trying to use this Country API.

Body

I'm trying to use a Countries API in one of my projects. I'm trying to integrate the API services. I saw some online tutorials, I've used postman API to check and it gives some data. So how do I do the integration in the code.

You can integrate the Countries API using a simple HTTP request. For example, if you're using JavaScript with the fetch API, you might do something like:

async function getCountries() {
  try {
    const response = await fetch('https://restcountries.com/v3.1/all'); // replace with your API endpoint
    if (!response.ok) {
      throw new Error(`HTTP error! Status: ${response.status}`);
    }
    const data = await response.json();
    console.log(data); // do something with the data here
  } catch (error) {
    console.error('Error fetching countries:', error);
  }
}

getCountries();

If your API needs headers (for example, an API key), you can pass an options object to fetch:

async function getCountries() {
  try {
    const response = await fetch('https://api.example.com/countries', {
      method: 'GET',
      headers: {
        'Content-Type': 'application/json',
        'Authorization': 'Bearer YOUR_API_KEY' // if needed
      }
    });
    if (!response.ok) {
      throw new Error(`HTTP error! Status: ${response.status}`);
    }
    const data = await response.json();
    console.log(data);
  } catch (error) {
    console.error('Error fetching countries:', error);
  }
}
getCountries();

This is essentially what you did with Postman, but inside your code. You can then use the data variable to update your UI or do further processing.
