Is there any API in 'Click&Pledge' payment gateway for processing the transaction later using code. Can we hold a transaction and process them later on using code. There is any similar feature like authorize.net for holding a payment and process them later by code. As authorize.net provide api for CaptureTransaction. We send transaction data using api to authorize.net and authorize.net return gateway_transaction_id that we use to process a CaptureTransaction later using code. Also there is any api for refund a payment and recurring a transaction on a particular date.
