Connect sberbank acquiring to the site

We have an ongoing project. http://my.aptekabriz.ru/ In a project, an administrator can create orders for customers. http://my.aptekabriz.ru/admin/orders (button "Add order") As soon as the order is created, the customer is sent an SMS. It is necessary to do: 1. Connect acquiring from Sberbank. 2. In the text of the SMS, insert a link to acquiring. 3. When the order is paid, you need to change the status of the order on the page http://my.aptekabriz.ru/admin/orders Now all orders when they are created are assigned by default the status "Not paid". If the payment has passed, then you must automatically change the status to "Paid".
The site is written in php msql without using cms and frameworks
