Can I link my own ordering website to the Instagram Order food button?

Not on the button. Order food works only through a partner on Instagram's list for your country. Put your own ordering link in your profile instead.

• The button: needs a business or creator account and an account with a listed partner.
• Your own link: add up to five links to your profile from the app (Edit profile, Links, Add external link).
• Anyone can see those links, on or off Instagram.
• Lead with your ordering link and name it clearly, for example 'Order here'.
