# 05th Feb: Meta OAuth Migration to Permanent Access Tokens, StackAdapt Pixel Support and more

### :sparkles:New and noteworthy

#### **Meta Authentication Migration to Permanent Access Tokens**

We’ve improved the transition from Meta OAuth to permanent access tokens by updating all guidance and recovery flows. Authentication emails now clearly explain how to fix issues using Pixel Access Tokens instead of legacy OAuth steps. We’ve also introduced a dedicated migration page that makes it easy for existing customers to add and manage their Pixel Access Tokens in one place, ensuring a smooth and reliable upgrade.

#### Improved InitiateCheckout Tracking for Shopify Express Checkout

We’ve added a more reliable way to trigger the InitiateCheckout event for Shopify Express Checkout flows, including Shop.app redirects. Instead of relying only on browser pixel behavior, the system now detects checkout actions directly and fires the event instantly using cached cart data. This ensures checkout intent is captured even when customers are redirected offsite, without duplicate events being fired.

#### StackAdapt Pixel – Browser-Side Support

We’ve added browser-side support for the StackAdapt Pixel using a fetch-based implementation. This enables StackAdapt Pixel events to be triggered directly from the client and supports view-through conversion tracking based on IP, in line with StackAdapts Pixel API behavior.

<mark style="color:$primary;">What’s new</mark>

* Browser-side firing of StackAdapt Pixel events via `fetch`
* Support for view-through conversions using IP-based attribution
* Continued support for conversion tracking, engagement, and audience building

<mark style="color:$primary;">Impact</mark>

* Complements the existing server-side integration.
* Event tracking continues to function as expected.

### :zap:Improvements

* \[Channel] - The `init` response now includes the visitor IP address to support integrations like StackAdapt Pixel.

### :bug: Fixes

* \[App] Authentication error emails will now be also delivered to Blotout Slack channels, ensuring faster visibility and response even when email verification is not present.
