Facebook graphic api get email

The Facebook Graph API!

To retrieve a user's email address using the Facebook Graph API, you'll need to make a request to the /me endpoint and include the email permission in your authorization request. Here's a step-by-step guide:

Prerequisites:

  1. Create a Facebook Developer account and register your app.
  2. Set up a Facebook Login button on your website or mobile app.
  3. Configure the email permission in your app's settings.

Authorization:

To retrieve a user's email address, you need to authorize your app to access the user's email. You can do this by adding the email permission to your authorization request. For example, in JavaScript:

FB.login(function(response) {
  if (response.authResponse) {
    // User authorized
    FB.api('/me', { fields: 'email' }, function(response) {
      console.log(response.email); // User's email address
    });
  } else {
    // User declined authorization
  }
}, { scope: 'email' });

In this example, we're using the Facebook JavaScript SDK to prompt the user to authorize our app. We're requesting the email permission and, if authorized, we're making a request to the /me endpoint to retrieve the user's email address.

Graph API Request:

The /me endpoint returns a JSON object containing the user's profile information, including their email address. You can specify the fields you want to retrieve by adding a fields parameter to your request. For example:

GET https://graph.facebook.com/v13.0/me?fields=email

This request retrieves the user's email address and returns it in the response.

Response:

The response will contain the user's email address in the email field:

{
  "id": "1234567890",
  "email": "[email protected]"
}
