How to setup Shopify-managed installations for Node Express App

I am wondering how to set up Authorization using Shopify-managed installations for the Node Express App

Based on this repo. It is still using the old method: Implement authorization code grant manually

I’ve already set up Shopify.app.toml config file to satisfy Shopify-managed installations.
Then, how can I request the Shopify Admin API in my Express app server?
and do I need set up any OAuth flow in Express App (verify request, install, …)?

In the old method (manually implementing the authorization code grant). I use a session stored in sessionStorage to make the request to the Shopify Admin API valid

Hi @Cuong_Vu_Manh

You can refer to Shopify’s official express template:

Shopify/shopify-app-template-node

They still use old method (Implement authorization code grant manually)
Navigate to exitiframe path then re-auth
