StorefrontAccessToken "App must be extendable"?

[shopcam]

I'm trying to access the Storefront API. I've changed my app to be a sales channel and now I'm trying to create a StorefrontAccessToken. When I try to create the token, I get a 403 error that says "App must be extendable to create a storefront access token."

How do I make my app extendable?

Hi @shopcam 

Make sure that your all follows all requirements of being a channel : https://shopify.dev/concepts/channels

Sounds like either your app is not embedded, or you are requesting the wrong type of scope. Are you creating a sales channel for a marketplace or other channel, or looking to interact with the Storefront API for your own website?

Hi @vix 

We are trying to fetch storeaccesstoken and ours is not a sales channel, but want to interact with StoreFront API for own external ecommerce website. Any suggestions on how to get this so that we can create shopify checkout weburl?
