How to integrate shopify to instagram channel

Hi,I have an online store on Shopify and have linked all my sales channels for facebook up. The only one that is not going through is Instagram. It says to verify the domain to add my catalog to Instagram, and have followed through with the steps. i have tried all 3 methods, and yet none of them are working. Please help me link my shopify store with my instagram page. Thank you
