Authenticate the Facebook App
Dynamics 365 portals are capable of hosting Facebook Apps in the context of a Facebook Page Tab. This is achieved by employing features such as Login with Facebook and ASP.Net MVC Display Modes.
Start by setting up a standard portal.
The same website used to host the standard portal is also used to host the Facebook App portal. However, the website must be configured to respond to Facebook-specific site bindings in addition to the existing bindings. The specific site bindings should contain a host name value that distinguishes it as a Facebook App portal. For example, a standard portal hosted from the domain contoso.com can specify the domain facebook-contoso.com for hosting the Facebook App.
|http||contoso.com||80||The standard portal.|
|http||facebook-contoso.com||80||The Facebook App portal.|
|https||facebook-contoso.com||443||The Secure Facebook App portal.|
Configure display mode
The MVC Display Modes feature allows the Facebook App to present a customized user experience. The Facebook display mode is enabled by adding the following site setting.
|Site Setting Name||Value (examples - replace with your Page Tab URL)||Note|
|DisplayModes/Facebook/HostName||facebook-contoso.com, facebook-*||The host name of the Facebook App portal. Accepts wildcard.|
Test the site bindings
View the portal through each of the site bindings in a web browser to ensure that the bindings are functioning correctly. Verify that the Facebook site bindings render a customized view distinct from the other bindings
Set up the Facebook app
- Go to the Facebook Developers site and sign in by using a Facebook account. Under theMy Apps drop-down menu, select Add a New App, and then select Skip and Create App ID.
- In the resulting Create a New App ID dialog box, specify a valid Display Name,Namespace, and Choose a Category (such as Apps for Pages) because this will eventually be required to publish an app to the public. The Namespace can be left blank. Select Create App. Submit the Security Check (captcha) as well.
- After landing on the Dashboard, go to the Settings area in the left column navigation.
Complete the Basic form by entering the fields shown in the following example:
Display Name: Contact Email
Contoso Portal: email@example.com
Display Name: App Domains
Contoso Portal: portal.contoso.comfacebook-portal.contoso.com
If the domain values cannot be successfully set, leave this field blank for now, complete the next step to specify a Site URL, and then return to this field.
Select + Add Platform, and then select Website from the Select Platform dialog box. Enter a Site URL (for example: http://contoso.com)
Again, select + Add Platform, and this time select Page Tab. Complete this new section based on the following fields:
- Secure Page Tab URL: https://facebook-contoso.com/app/facebook
- Page Tab Name:Contoso Portal
The Page Tab URL should have the /app/facebook path appended to the App domain URL. The portal uses this endpoint to launch the App portal.
Select Save Changes.
Take note of the App ID and App Secret values of the new app. Use these values when configuring the site settings. The two Authentication Site Settings that need to be configured are:
The Value and Website of each site setting must also be added into the site settings.
The Facebook Authentication Site Settings may require the Website's Application Pool to be recycled before they are functional.
Publish the app
- Go to the Status & Review area (under the Settings area).
- Set the first option of the Status tab Do you want to make this app and all its live features available to the general public? to YES.
Add the Facebook page tab to your Facebook page
If you do not have a Facebook Page, follow the instructions here to create one Create a Page. If you will be using an existing page, the current Facebook user must have sufficient permission to add a Page Tab to the Page. If your Facebook Page does not already have the Page Tab functionality enabled, you must enable it by browsing to a specific URL (substituting the relevant App ID and "next" URL value). The URL below can be used if you substitute the App ID and encoded URL with your information. Further details can be found in Using Page Tabs and URL Encoding.
This displays the Add Page Tab dialog to select the Page that will contain the Page Tab and app. Browse back to the Page and the app should be available in the grid of added Page Tabs. Select the Page Tab to view the Facebook App portal framed within the Facebook Page.
Update the App portal to publish a Platform for Privacy Preferences (P3P) policy
By default, Internet Explorer does not allow third-party cookies to be created for portals/apps that are rendered in an iFrame of another host portal. This is the case of a Facebook App portal hosted from a Page Tab. A side effect of this cookie blocking is that an app is unable to create and maintain an authenticated session. This is resolved by updating the App portal to publish a Platform for Privacy Preferences (P3P) policy. There are various options for achieving this one of which is to update the web.config of the App portal to include a custom header. For Example:
<configuration> <system.webServer> <httpProtocol> <customHeaders> <add name="P3P" value='CP="ALL ADM DEV PSAi COM OUR OTRo STP IND ONL"'/> </customHeaders> </httpProtocol> </system.webServer> </configuration>
