Opencart API is the solution to your problem. Watch the video below:

The OpenCart API allows your application to access current data within OpenCart. Through the API, several common operations can be performed on OpenCart. Operations include:
create — Creates with the specified parameters.
For example, you can add products to the cart as given by OpenCart API post request of products or product_id at
/index.php?route=api/cart/add
read — Retrieves information about the specified object.
query — Retrieves objects that match specified criteria.
update — Updates elements of an existing object.
upsert — Updates elements of an existing object if it exists. If the object does not exist, one is created using the supplied parameters.
