Develop a pricing parser module for an OpenCart store (OcStore 3.0.2.0)

For an online store on the OcStore 3.0.2.0 engine, you need to develop a module (or find, adapt and customize an existing one on the market) that would take prices, descriptions and characteristics of goods from several sources (other online stores) and place it on ours. I would add new products if they dont already exist and update existing ones.

It is necessary to provide for the possibility of adjustment for the future, if the source suddenly changes the format of the data.

The direction of activity of the online store: mattresses, beds and bedding.
