Last year Facebook updated its policies  and with this, change the usual way of pixel tracking. After those changes any given domain can host a maximum of eight events and therefore it becomes practically impossible for platforms such as Prelaunch.com to keep Pixel running on all their product pages.
Facebook also requires advertisers to verify their own domains with their Facebook Business Manager. As your product page is hosted under Prelaunch.com and you  do not technically own the domain , ( the old  Facebook Pixel can not be used  directly on Prelaunch.com product page.) we came up with a workaround, which  is our back-end server that will deliver events from your Prelauch.com product page directly to Facebook's server under your domain name.

Here is a short summary of steps on how to use this solution. Later in this document we will cover each step in more details

‍

1. Register domain. If you already have domain for your product then skip this step
2. Verify your domain in your facebook Business Manager
3. Create a new Facebook Pixel in your Facebook Ad Account. 
4. Create events that need to be tracked in your Facebook Business manager (currently we are supporting only ViewContent , Lead, Purchase events. PageView event tracked automatically )
5. Send Pixel ID,Pixel token and you domain name to Prelaunch.com
6. Share you Pixel read access with Prelaunch.com Business Manager
7. Run your facebook advertisement. 

‍

Step 1. Register a Domain

In order to purchase a domain you need to go to any domain name registrar such as Bluehost, GoDaddy or any other and find a suitable domain for your product. As this domain will be used for sending Pixel events to Facebook conversion API it does not require to be very expensive domain,so any domain that can be verified in your Facebook account will do the work,  however it is strongly recommended that you choose a meaningful domain name that somehow relates to your product as at some point you might want to use it for some other purposes.

‍

Step 2. Verify your domain in Facebook account

Domain verification on Facebook is happening using DNS verification. The recommended way of actions is to have separate domains for each Pixel: meaning that if you have two products on which you want to run advertisements then you need to have two separate domains and verify them in your facebook business manager.

Check out Facebook documentation on domain verification. 

1. Go to the Settings tab in Business Manager and click Brand Safety then
   Domains.
2. Click Add New Domains button.
3. After adding a domain you see the steps necessary to verify your domain with a DNS TXT record or through HTML File Upload.
4. DNS verification is the simplest method. 
5. Go to your domain registrar and navigate to the DNS settings page.
6. Add a new TXT record to your domain.
7. Wait for your DNS changed to be accepted then return to Business Manager and click Verify button

Here is Facebook video on how to pass the domain verification step

Step 3. Create new Facebook Pixel and add events that need to be tracked.

1. Go to your Ad account and under Event Manager click on “Connect Data Sources” 

‍

2. On the opened popup select “Web”.
   
   

2. Name your pixel. It’s strongly recommended  to name your pixel as your Prelaunch.com product name.  That would make it easy for us to find you. Pixel when you share it with us.

‍

4. Follow “Continue pixel set up”  and then  click on “Install code manually

‍

5. Select the events that are going to be tracked on Prelaunch.com.

1. PageView  - this event is triggered when page is loaded
   
   
2. View content - this event will be triggered when your Prelaunch.com product page is loaded and is scrolled to 75%.
   
   
3. Lead - this event will be triggered when someone subscribes to your product Prelaunch.com
   
   
4. Purchase - this event will trigger when someone makes a deposit on your product Prelaunch.com page.

‍

6. For each one of the events, please select the following parameters in order for your Ads to perform more effectively. 

1. Event ID
2. _fbp
3. Client IP Address 
4. Browser ID (fbp) Cookie
5. External ID
6. Country
7. State
8. City
9. Click ID (fbc) Cookie
10. Email (hashed with SHA256)
    
    

‍

7. After adding parameters to all events just press on “Continue” to review the whole setup.
   

7. Pass to the next step and then press “Finish: button. No need to send instructions to anyone, this part is already covered by our backend system

Step 4: Provide Pixel ID,Pixel token and you domain name to Prelaunch.com

As of now your Pixel information and domain name can be shared with us by sending mail to “support@prelaunch.com” email address. Please make sure to specify to use following subject line for email
“Pixel for [product name]” , this will help us to identify your pixel faster and make necessary configuration changes.

Please also make sure that you have provided your Pixel information to us before starting advertisement on your product.

In the nearest future we will provide you an option to set this information in your project settings directly in the Prelaunch.com platform.
