If your Instagram feed has stopped working, you likely need to update your theme first. You can then continue to use your existing token or return here to generate an access token.Update Your Theme First
If your Instagram feed is not working, you most likely need to update your theme before generating a new access token.
This token allows the theme to securely access your Instagram profile, for the sole purpose of displaying your Instagram photo feed in your shop.
By clicking the button on the left, you'll be prompted to log in to your Instagram account and authorize Out of the Sandbox to access your Instagram photos. Then you should be given a code that looks like a very long string of numbers and letters.
Once you have the token code, you'll just need to copy and paste it into your Theme Settings in the Home Page > Social Feeds section along with your Instagram username and you'll be all set!
