Looking for an experienced developer to make a Magento module for payment processing via an API. We need to send information on a Magento ecommerce checkout to our payment system via an API and receive a response for the payment status. Also, our ecommerce landing page receives some variables that need to be saved on landing and be sent as well (following a JSON file specification) to our system on the checkout form. Since our checkout has 2 steps, the form data will need to be sent on each step so we can still have data even with an abandoned cart.
I am willing to pay higher rates for the most experienced freelancers
