# Manually call API

# Configure callback URL

You need to set a callback link (Callback URL) on the configuration page of social login, and the user will be redirected to the callback address after logging in:


# Guide users to the social login authorization page

This method is only applicable to social login on the Web side. If you need to initiate a social login in the mobile App, please read the documentation of the relevant social login service provider.

This operation should be done in the browser. You can place a clickable button or Logo link on the Web page to the link above so that users can click to log in.

The following is the authorization page link corresponding to each web social login, where YOUR_APP_ID ​​is your application ID (note not the user pool ID). You can view the application ID on the application list and application details page.

# Processing Authing callback request

After the user agrees to the authorization in the previous step, it will jump to the Authing server first, and then Authing will carry the user information to jump to the business callback link configured by the developer in the Authing console, with the following Get request parameters:

Parameters Description
code Error or success code, 200 is success, non-200 is failure
message Success or error message
data userInfo, if code is not 200, this parameter is not returned

Some browsers and Web Servers may have a 404 when the URL is too long, such as ASP.NET. At this time, you need to modify the configuration. For details, see [This StackOverflow Answer](https://stackoverflow.com/questions/ 28681366/in-asp-net-mvc-would-a-querystring-too-long-result-in-404-file-not-found-error/28681600).

The following is the code that uses JavaScript to get user data from URL parameters:

// Get URL parameters
function getQueryString(name) {
  var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)", "i");
  var r = window.location.search.substr(1).match(reg);
  if (r != null) {
    return unescape(r[2]);
  return null;

// Convert Code to Int type to facilitate judgment
const code = parseInt(getQueryString("code"));

if (code !== 200) {
  // error
  const errorMsg = getQueryString("message");
  // Show errorMsg to users or perform other business...
} else {
  const userInfo = getQueryString("data");

  // Store token in localStorage
  // It is recommended to attach Token to subsequent requests and verify the validity of Token by the backend
  localStorage.setItem("token", userInfo.token);

# Next

After obtaining the user information, you can get the login credential token. You can carry this token in subsequent API requests, and then distinguish different users based on this token in the backend interface.
