Hi Peter
We just wanted to implement feed data into a banner template. The problem was that we got that invalid 4th party call errors trying to do this. That means that we have a data feed with prices and dates for our services and a GDN banner template. After someone had visited a specific product on our site, we want to show him our banner template with data from our feed. Up to now, our banner is rejected in AdWords because our server is not white labelled (invalid 4th party call). But white labelling is a long procedure and we would need a big amount of impressions.
One idea was to host the data feed on one server that is white labelled, like for example a 1&1 server.
But we are open for other ideas.
