Following the tutorial on Shopify CLI I have built a simple nodejs application. Everything works great. I have an external application with API (it would use Shopify Python SDK) to connect to specific store. Checking the docs, I would need access_token to access the store.
I already have the initial app that has access_token. My question is how to connect everything? Should nodejs app send access_token to external application so it can communicate with store via Shopify API using provided access_token? I know there is an example to request an access_token, but this only asks for permission to access store data that I already have.
What do you suggest? The flow is that within nodejs application I would make a HTTP request to external application which would update the store using API.
