Integration 1C with a site in PHP, how best to implement?

Question

Yii

Hello!
There is an online store that runs on Yii2. At the request of the customer, now I have to integrate the store with 1Сom. I haven't experienced this before, so I don't know what to do yet.
In the end, I decided to do all these myself .. but I don’t know where to start yet.
So the task is this.
There is an Internet store and 1C trade management edition 11.2
and the data integration should be in real time (and not uploading and downloading XML files)
The customer wants him to be able to
- sees and track orders in 1C and accept or reject them
- sees the list of suppliers and buyers and change their data
- sees the list of goods, change quantity, remove from sale, etc.
- sees analytics by districts, etc.
- generate files for printing (excel file or just a check) The
question is: is it possible to implement all these tasks in 1C?
I've seen several video tutorials ... it seems possible ... but I still don't understand how to do it
Please give advice or a good source of documentation or video tutorials
