Facebook search by email address api

Facebook provides a few ways to search for a user by email address using their API. Here are a few options:

1. Facebook Graph API - Search for User by Email

You can use the Facebook Graph API to search for a user by email address. You'll need to make a GET request to the /search endpoint with the q parameter set to the email address you're searching for.

Here's an example:

GET https://graph.facebook.com/v13.0/[email protected]&type=user

Replace [email protected] with the email address you're searching for.

The response will contain a list of users that match the search query. If the user is found, the response will include their Facebook ID, name, and other information.

2. Facebook Graph API - Search for User by Email (with permissions)

If you have the email permission for the user, you can use the /search endpoint with the q parameter set to the email address and the fields parameter set to email.

Here's an example:

GET https://graph.facebook.com/v13.0/[email protected]&type=user&fields=email

This will return the user's email address if they match the search query.

3. Facebook for Developers - Search for User by Email

Facebook provides a search bar on their Facebook for Developers page that allows you to search for users by email address. You can use this search bar to find a user's Facebook ID, which you can then use to retrieve their profile information using the Facebook Graph API.

Here's an example:

  1. Go to Facebook for Developers.
  2. Click on the search bar at the top of the page.
  3. Enter the email address you're searching for.
  4. Click on the search button.
  5. If the user is found, their Facebook ID will be displayed.

You can then use the Facebook Graph API to retrieve the user's profile information using their Facebook ID.
