It can be, for example, full information about customer order for *ADD/CHECKOUT* event, or you may be want to store user image in your CDP guest profile. In this article I will show you how to do it. #### How to pass extended data in CDP event? It is easy to do. All that you need just to pass any addditional data that you want to **ext** field in your event request. Example for *CHECKOUT* event where we pass information about guest order and custom **facebook\_event\_id** field: Helper for event triggering: ``` export const sendBoxeverEvent = (type, options, callback) => { const { page, currency, ext } = options; _boxeverq.push(function () { const boxeverEvent = { browser_id: Boxever.getID(), channel: 'WEB', type: type, language: 'EN', pos: window.location.host, currency: currency || 'EUR', page: page || '/', ext: ext, }; Boxever.eventCreate( boxeverEvent, function (data) { if (callback) callback(); }, 'json' ); }); }; ``` Example of execution: ``` sendBoxeverEvent('CHECKOUT', { page: window.location.pathname, ext: { facebook_event_id: "df2e518d-5004-43b2-b53c-5e6a0021dede", cart:[{ProductID:"M00003", Quantity:6, UnitPrice:37}], total:345.45 } }); ``` This event will be send to CDP and stored in format:![Sitecore CDP - Checkout event](https://www.brimit.com/-/media/project/brimit/blog/2021/x3mxray/3/checkout.jpg) #### How programmatically get extended event data? You just need to select your event and add get extended data by hitting **event.arbitraryData.ext** property. #### How to store extended data in guest profile? First of all, before send any data to guest profile need to setup **Authorization Basic** header for your requests. Otherwise you will receive an error: ``` { "status": 401, "code": 401, "message": "Authentication required.", "developerMessage": "Authentication with a valid API Key and API Secret is required.", "moreInfo": "mailto:support@boxever.com" } ``` In your CDP account navigate to **System Settings -> API Access** and copy **Client Key** and **API Token** values. You can generate valid auth header by using [this online tool](https://www.blitter.se/utils/basic-authentication-header-generator/), use **Client Key** as ***Username*** and **API Token** as ***Password***. Or you can generate it in your javascript yourself, basic auth pattern is: ``` (`${username}:${password}`).toString("base64") ``` If you don`t know you current Guest Id value, you can find your Guest CDP-address by email with GET request to **https://api.boxever.com/v2/guests?email=userbuyer1@test.com** endpoint with valid auth header: ![Sitecore CDP - Find user by email](https://www.brimit.com/-/media/project/brimit/blog/2021/x3mxray/3/search_by_email.png) In response you will find link to your Guest. To send extended data to Guest profile you need to make POST request **https://api.boxever.com/v2/guests/{your\_guest\_id}/extExt** endpoint with JSON body in **{key: "", value:""}** format. Example how to add **logo** property to Guest profile to store user photo: ![Sitecore CDP - Send guest extended data](https://www.brimit.com/-/media/project/brimit/blog/2021/x3mxray/3/logo.jpg) If your request is successfull, you can navigate to CDP **Guest properties** and find your posted value in **Ext** field:![Sitecore CDP - Guest extended properties](https://www.brimit.com/-/media/project/brimit/blog/2021/x3mxray/3/ext.jpg) #### How programmatically get extended profile data? You just need to iterate guets data extensions and select your one by key. For our example with logo: ``` for (var i = 0; i < guest.dataExtensions.length; i++) { if (guest.dataExtensions[i].name === 'Ext' && guest.dataExtensions[i].key === 'logo') { var logoExt = guest.dataExtensions[i].values; return logoExt.url;} } ``` Here goes the table of contents for my Sitecore CDP blog series: - [Introduction](https://www.brimit.com/blog/cdp-0-intruduction) - [How to connect Sitecore CDP to website](https://www.brimit.com/blog/cdp-1-how-to-connect-to-website) - [Debugging tools](https://www.brimit.com/blog/cdp-2-debugging-tools) - How to pass extended data to Sitecore CDP - [How to use Data System connections (Decision model with Content Hub products)](https://www.brimit.com/blog/cdp-5-how-to-use-data-system-connections) - [How to use AI connections (Web experience with Azure Cognitive Services)](https://www.brimit.com/blog/cdp-4-how-to-use-ai-connections) - [How to use Destination connections (Triggered experience webhook)](https://www.brimit.com/blog/cdp-6-how-to-use-destination-connections) - How to use External service connections (Flows with External Service) - Remarketing with Sitecore CDP and Facebook Ads ###### Author ![sergey-200](https://www.brimit.com/-/jssmedia/feature/blogs/authors/sergey-200.jpg?h=197&iar=0&w=200&hash=0D636570F87F1C13C39E06EB19D9DF06) Sergey Baranov Sitecore MVP/ Senior Sitecore Developer [Sergey Baranov](https://www.brimit.com/blog/author?authors=Sergey%20Baranov) ###### More By Categories [#Events](https://www.brimit.com/blog?categories=#Events) [#How-to](https://www.brimit.com/blog?categories=#How-to) [#News](https://www.brimit.com/blog?categories=#News) [#Guides](https://www.brimit.com/blog?categories=#Guides) ###### More by Platform [Data and AI](https://www.brimit.com/blog?platforms=Data%20and%20AI) [DXP](https://www.brimit.com/blog?platforms=DXP) [E-commerce](https://www.brimit.com/blog?platforms=E-commerce) [Internet of Things](https://www.brimit.com/blog?platforms=Internet%20of%20Things) [Sales and marketing automation](https://www.brimit.com/blog?platforms=Sales%20and%20marketing%20automation) #### More on Sitecore ![How Vercel Will Help You Save Effort When Deploying Sophisticated Sitecore Projects](https://www.brimit.com/-/jssmedia/project/brimit/blog/2024/vercel_cover-image.png) #Guides #How-to DXP E-commerce ##### How Vercel Will Help You Save Effort When Deploying Sophisticated Sitecore Projects Optimize and accelerate the development and deployment of complex multisite Sitecore projects.
