In order to use the built in Instagram widget on your store we first need to get some permission from Instagram to allow those images to be shown by means of an Access Token.
Click on the button below, this will bring up an Instagram prompt asking you to Authorize the Underground feed to access your Instagram photos.
We do not have any access to your account or images, this simply lets our app do it's thing and show those images on your store. You should then see a confirmation page with a long string of numbers displayed.
Thanks for completing those steps, here's your Access Token:
Copy this number and head over to the themes > customize theme section of your Shopify store. Select the Home page - Instagram feed section and paste this in to the field labelled: Instagram Access Token
If you do not have your user ID number don't worry it is the first 8-10 numbers of your access token right before the "." Copy that part also into your User ID field.
For example the ID in the token will like this: 1234567890.1ab0101.1abc12a345678ab12345a12345678a1a
