I'm attempting to integrate a hosted payment page using Authorize.Net
I have successfully installed the SDK using Composer (including dependencies) and got the Hello World example working.
However, when trying to create a hosted payment page using the sample code provided, I get the following error:
PHP Fatal error: Class 'net\authorize\api\contract\v1\GetHostedPaymentPageRequest' not found
I'm guessing this is some namespace issue, but I can't trace it. Changing the class name key as per this issue on GitHib seems to have no effect.
