I'm currently working on PayPal Adaptive Payments with Pre-Approval. I have followed the Steps on this link. So far I'm able to make a link and Process the Pre Approval until I login to PayPal and Proceed to Authorizing the Payment.
My problem now is when it's already the Start/End Date:
$preapprovalRequest->startingDate = "2016-11-06";
$preapprovalRequest->endingDate = "2016-11-07";
The Pre-Approved Payments are not automatically Triggered on the specified Date. Is there another Step that I need to do? Or a trigger?
