To view ratings on the page using the Facebook Graph API, we can make a GET request to the ratings edge of the page object using the page's ID and a page access token that has the pages_read_user_content permission. Click the “Run” button to see the response.

Javascript (babel-node)
// Importing libraries here
import fetch from "node-fetch"
// Define endpoint URL here
const endpointUrl = new URL("https://graph.facebook.com/v16.0/{{PAGE_ID}}/ratings");
const headerParameters = {
    contentType: "application/json",
};
// Setting API call options
const options = {
    method: "GET",
    headers: headerParameters,
};
// Define Query Parameters here
const queryParameters = new URLSearchParams({
    access_token: '{{PAGE_ACCESS_TOKEN}}',
    limit: '10'
});
// Function to make API call
async function fetchPageRatings() {
    try {
        endpointUrl.search = queryParameters;
        const response = await fetch(endpointUrl, options);
        // Printing response
        printResponse(response);
    } catch (error) {
        // Printing error message
        printError(error);
    }
}
// Calling function to make API call
fetchPageRatings();
