The usual process to implement a Social Login is stablishing a connection with the API of each Social Network you may have chosen as a registry method.
With the Xeerpa connect BackAuth product you will only need to stablish a connection with Xeerpa, as the product will take care of these connections itself. That way you don't need to know how each Social Network API works, Xeerpa Connect BackAuth will handle all these connections for you. How?
- When users click on the login button Xeerpa Connect BackAuth is activated and automatically establishes the connection with the API of the social network selected, authenticating the user.
- The solution also establishes the connection with the Xeerpa web service in order to analyze the user.
- Furthermore, Xeerpa Connect BackAuth allows for the addition of more social networks at a later stage, quicker and with greater ease, aleviating your IT team from the task of monitoring for changes to the APIs of the various social networks.
Moreover, Xeerpa Connect BackAuth offers the following advantages::

You will not have to worry about any change in the policies of privacy and use of social API data. We will take care of maintaining the product updated.
Gather more advanced analytics which will allow you to know the details about the conditions the user has logged in with. We will have get more analytics of the users that have logged in from a SL connected to a XCBA.
This is the basic data flow designed for Xeerpa Connect BackAuth using Facebook:
This section assumes you are familiar with the creation and configuration of apps in the desired social networks. To learn more about this please visit the section Social Network Apps.
Step 1: Information you'll need to send us
After choosing and configuring your app with the appropiate Permissions and Callback URL, you need to send the following information about each of your apps to email@example.com :
Step 2: Implement the Social Network Login Buttons
Upon request Xeerpa can provide sample code for implementing step 2 and step 3 of this document for PHP and Node.js. Please do not hesitate to inquire at firstname.lastname@example.org
2.1 Render your social network buttons in your website or promotion
- Color: It must be the Social Network's official color.
- Logo: Use the official logo which will be available in the Brand Guidelines. Do not use old logos or custom variations.
- Copy: We recommend you to use a phrase related to the call to action. These messages help improve the conversion rate. For example: "Login with.." or "Continue with.."
These are some examples of the buttons:
When the user clicks on one of these buttons you must open a new window popup and make a call to your own server to respond to this on
2.2 In your server, create the entry point to receive the on
FB: Facebook, TW: Twitter, LI: LinkedIn, GO: Google, IG: Instagram
Xeerpa will respond with a JSON. If errorCode is not 1 you should deal with the error. Otherwise you mut redirect the popup to the url specified in the response:
"url": "https://www.facebook.com/dialog/oauth?display=popup&response_type=code&redirect_uri=http%3A%2F%2Ftest.com%2Ftest%2F%2FresponseCallback.php %3Frid%3D5SQR8N9V15_iUaRgbZ1_h_9fjjjjcijb9ha75fc4iicage&scope=public_profile,email,user_friends,user_birthday,user_location,user_likes,user_tagged_places,user_posts&client_id=17347454208“
2.3 Create the socialLoginCallback point in your server (avoid using the word Xeerpa). This will be used one or more times (depending of the social network) to stablish a dialogue between Xeerpa and the social network. The information may arrive in your entry point by GET, POST or both, so it must be aggrupped and then sent to Xeerpa with a GET request.
For example, if a social network returns “aaa=123" by GET and "bbb=456“ by POST, you should construct the call to Xeerpa like that:
The response from Xeerpa will be a JSON similar to the step 2.2, and the next step depends of the presence of the property "fields" in the JSON:
- if there is no "fields" property in the JSON, you can simply redirect the popup to the JSON's url property.
- If the response does contain the fields property, you will have to make a POST request to the JSON's url passing the fields value as the body of the request.
For example, "https://www.linkedin.com/uas/oauth2/accessToken"
For example, "ccc=789&ddd=0"
The response will always be a plain text that should be included as a query parameter called "data" to the popup's current url and redirect it to that new address.
2.4 Create the socialLoginCompleted point in your server as specified in Step1.1 (avoid using the word Xeerpa). The last redirection made by the socialLoginCallback entry point is to your own server, passing the user information in JSON format.
JSON with user’s data. Some data could be empty depending on the Social Network.
At this point you should pass the user information back to your page, using postMessage, cookies or any other method of your preference. You may also securely process the user information and store it on your own database.
Optionally you can call Xeerpa to assign Robinson, a user’s CRM ID or extra data using Xeerpa's user ID and token:
Finally you can close the popup or display a widget that helps you getting some social networks' special permissions. For more information read the next step.
Step 3: Obtain advanced user permissions
For Xeerpa to be able to gather and process the most important social information from the Facebook users, the Facebook Application linked to your Facebook Xeerpa Connection must be allowed to request the permissions to extract the advanced details. You can find more information about these permissions here.
Facebook reviews all the permission requests for every Facebook App, and this approval must be granted once for each Facebook App. You can use the Xeerpa Connect Summary Widget to obtain these permissions (user_birthday, user_location, user_posts, user_tagged_places, user_gender, user_friends and user_likes) - please feel free to request any further information about this Widget, contacting us through email@example.com.
Using Xeerpa Connect Summary Widget for Facebook
This Widget will be returned by Xeerpa as a JSON with some basic HTML which can be customized to match the look and feel of your website, mobile applicaiton, or WiFi hotspot, and can be extended to provide a more personalized user experience. Please check our Summary Widget article.
The Summary Widget call is already implemented in the Connect BackAuth PHP files, though in case you prefer to add the calls to your own PHP file, you can manually implement the Summary Widget making this call:
