We can't load Amazon's scripts on any page before the Amazon-specific payments form. Once the donor gets to Special:AmazonGateway, they should be redirected to the Amazon authentication screen without having to click a button.
Some info on redirect authentication:

| Resolved | Ejegg | T108112 Spike: get Amazon authentication working with automatic redirect |
This has to be done via a Jacascript redirect (so not as fast as server redirect), but it turns out to be not that hard.
From the Javascript SDK Reference and the page linked above you can piece this together:
window.onAmazonLoginReady = function() {
amazon.Login.setClientId( OUR_CLIENT_ID );
amazon.Login.setUseCookie( true );
amazon.Login.setSandboxMode( true ); // if you want to use test accounts
if ( !loggedIn ) {
loginOptions = {
scope: 'payments:widget',
popup: false
};
amazon.Login.authorize( loginOptions, RETURN_URL );
}
}Then source either the widget script or just the login script. It'll call your function as soon as it's loaded and immediately redirect. With the Login.authorize call there's no need to simulate clicking on a button.
You can determine whether the user is logged in by looking at the hash that's appended to the return url, which you are then supposed to store in a cookie called amazon_Login_accessToken (for use by the widgets, I think).
