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:
- Create a Facebook Developer account and register your app.
- Set up a Facebook Login button on your website or mobile app.
- 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]"
}
Important Notes:
- The
email
permission is only available for users who have granted your app permission to access their email address. - The
email
field is only returned if the user has granted your app permission to access their email address. - The Facebook Graph API has usage limits and requires a valid access token to make requests.
