Hello, I'm writing my first Shopify app. Using react and nodejs, hosted everything on digitalocean private server. But came to the moment, where I got bit confused.. Where I can store my custom app data(such as third-party API keys, password, merchant custom settings). Appreciate if someone can show/tell me a correct way to do it. Basically on this app I will have only 3 custom fields which data needs to be stored. Shopify should have something like custom app settings metafields, no?
