Module for Magento Checkout Process

we are looking for a magento checkout module for an existing plattform for product recommendations. we can provide a detailed API description for this plattform. you should have deep experience with magento modules and the zend framework. From the user’s point of view, the plattforms concept can be illustrated using the following example: 1. Alice, a customer of the PetStore online shop, publishes information on her purchase in her social networks. The recommendation consists of two messages: An individual message, written by Alice, and a benefit message provided by the PetStore, describing the benefit Alice’s buddies will receive when making a purchase in the PetStore based on the recommendation. Each message contains a link. 2. Bob, a friend („buddy”) of Alice, sees the recommendation in Alice’s social network feed. 3. Bob clicks the link included in the recommendation. 4. Bob is redirected to the PetStore website and makes a purchase. 5. Bob obtains the promised benefit from the PetStore, e.g. a free unit of food for Bob’s pet. 6. Alice obtains a commission, e.g. 5% of the total amount of Bob’s purchase, which is wired directly to her bank account. The following tasks are mandatory to integrate a shop into the platform: • Provide a web page showing the current benefit • Integrate the sobu publishing service into the checkout process • Integrate the pay-per-sale tracking service into the checkout process • Integrate the plattforms publishing service into the customer’s order history • Integrate the plattforms publishing service into the order confirmation e-mail API general information Within the „Publish Purchase” use case, the shop passes information about the purchase to the plattform.
