If you're asking about setting up an Instagram store, I have had problems with integration as well. I set up a Facebook page as per instructions but they didn't allow me to open it as a business, even on multiple appeals, and so I was never able to integrate a Facebook store on our successful Instagram page. Ended up with a stand alone webstore using Shopify. We run major promotions via Shopify and just take EFT payment via Instagram for standard orders to avoid the crazy Shopify commissions.
Should have clarified.Do they have a preferred organic payment system that charges a handling fee. Cheers RB
Im still looking for help with the above integration. We have both FB business and IG shop set up but for some reason cannot connect them.
