+# Validate Social login token at back-end and get profile information
+
+# Social Login (IOS, Google, Facebook)
+- Create Web Project in developer console of social platform
+- Using developer console and get the access token then hit the API
+
+
+- Facebook PlayGround
+ - https://developers.facebook.com/tools/explorer/
+
+
+- Google PlayGround
+ - https://developers.google.com/oauthplayground/
+ - Scope : openid email profile
+ - Exchange authorization code for token then you will get id_token
+
+
+- Swagger
+ - http://localhost:8080/app/swagger-ui.html
+
+
+- For Facebook
+ - Request body
+ - {
+ "provider": "facebook",
+ "token": " Get access token from Playground "
+ }
+
+
+- For Google
+ - Request body
+ - {
+ "provider": "google",
+ "token": " Get id token from Playground "
+ }
+
+
+- For Apple :
+ - We need authorization code to validate on it.
+ - We are passing the values of firstName and lastName because when we get authorization code that time user-info will be provided after that only email will be received. This is current behaviour in APPLE doc.
+ - Request body
+ - {
+ "firstName" : "Hello"
+ "lastName" : "World"
+ "provider" : "apple",
+ "token" : "Get authorization code. It will be used only one time to validate and get the user information"
+ }
+
+
+- Important class and points
+ - SocialClient.java
+ - google and facebook api to get user info
+
+ - IOSConfig.java
+ - 4 properties we need from apple developer project
+
+ - IOSClient.java
+ - get apple user info
