Stape, GTM and Facebook Integration Specialist Needed

We are working as a marketing and advertising agency that specializes in restricted markets. We need someone to help us set up Stape for server-side tracking of website visitors, collecting as much information as possible about the customer’s journey, and then passing this information to Meta for optimizing the audience for conversions. However, we CANNOT show the URL of the website back to Meta, which is why we can’t just install a Facebook pixel on the website. WE CANNOT HAVE META PIXEL INSTALLED ON THE CLIENT WEBSITE. We want to track the session of the user from landing page (one domain), customer clicks YES, customer goes to the client's website (different domain), and then collect the data on the customer journey through Stape. HOWEVER WE CANNOT SEND THE URL BACK TO FACEBOOK because we are selling restricted products. So we need a way to change the URL Using GTM to the LANDING PAGE URL before data is sent back to Facebook to optimize our audience for conversions. The flow goes like this - Compliant ads go up on Facebook and are approved Clicks on those ads go to a landing page with a unique URL (not associated with our client) The landing page has an age-gate Customers click no, they are moved to a random page not associated with the client Customers click on yes, they are moved to our customer’s website or landing page We want to be able to use Stape to collect information to send back to Facebook but show that the traffic is coming from the landing page, NOT the client’s website, because the ads are set up with the landing page as the destination. If we send a URL to Facebook it must be the landing page URL (along with the data), and NOT the client’s website URL. It is important that we optimize traffic for conversions with Facebook so that our clients can see success on ad spend. We are looking for someone who knows how to do this process and can help us set it up. There would be recurring jobs happening multiple times a week for the person who can help us set this up.
