How can I connect my existing Facebook account to Shopify?

[bukkydipson]

Hello, I wanted to connect my instagram account with shopify. On myinstagram account my items as visible in the shop section but when i tried to add new items to my instagram shop from shopify it it wont let me. I have been having this trouble with connecting facebook and shopify for a very long time and can't find a solution. The situation is getting frustrating. I just need clear instructions and a way to keep/ connect my current instagram to my shopify store. Also i deleted facebook from the apps on my shopify sore and now I am unable to add the facebook app to my shopify.  When i click on add app in the shopify store it bring me to a page describing the following: 

There’s no page at this address

Check the URL and try again, or use the search bar to find what you need.

Therefore:

1. should i create a new facebook to connect it to shopify
2. should I link an existing facebook account (the account that I used to open my instagram) to connect to shopify

If anybody has any solution please let me know.
