🌐Verify sending domains

Verify, so Facebook knows you have the right!

🦄Protecting your data: Verifying sending domain is a way for Facebook to know that you have permission to send conversion data from the site to the pixel.

If they don't have this, imagine how everyone would be able to send malicious data to your pixel, messing up your pixel altogether!

Let's follow 8 simple steps to verify your domain!

📝**Preparation**:
Shopify side: You need to have access to the header section of your Shopify theme, or have contact with people that do.
Facebook side: Your account needs to be assigned with the Admin permission to be able to verify a domain

Copy the meta verification tag from Facebook

Paste the verification tag to the head section of your theme

Confirm verification

CAPI events for IOS 14.5 opted-out users: Two Owls Conversion API track 100% of sales, but for Facebook to be able to use that data for ad targeting or optimization, you need to ensure that the events are listed in the 8 prioritized conversion event list!

⬆️Set up Aggregated Event Measurement

About Aggregated Event Measurement for IOS devices.

Aggregated Event Measurement will let you send up to 8 different Pixel Events or Conversions per domain according to their priority.

This only applies to IOS users who opted out of tracking.

If a shopper takes multiple actions on your site within the conversion window, only the highest priority event will be sent.

📝For example, if the shopper makes it to the thank you page, only the purchase event will be used for retargeting or optimization, even though they did go through view content, add to cart, or other upper-funnel events.

Preparation

You need to have admin access to the Business Manager account.
Your Business Manager must have access to the Facebook Pixel you want to configure the AEM for.

Configure 8 events/conversions in Aggregated Events Measurement

Go to Web event configuration




Select the events you want to prioritize for targeting and optimization
****

Can I select custom events to prioritize in the AEM?
You can't directly select them but they're available for prioritization. Just create a custom conversion based on the custom events first, then you'll be able to select that custom conversion as 1 prioritized conversion.
