After enabling Custom Apps in your Shopify store, to get started you need to create a Custom App and install the Custom App. To do so:
From your Shopify admin, click Settings > Apps and sales channels.
Click Develop apps.
Click Create an app.
In the modal window, enter the App name and select an App developer. The app developer can be the store owner or any staff or collaborator account with the Develop apps permission.
Click Create app.
Configuring your Custom App
For aasaan to work correctly, you must configure two API scopes:
Admin API Scopes: aasaan will use these scopes to sync and manage your products and store assets.
Storefront API Scopes: Which are required for the Shopify Storefront APIs functionality (Cart, Customers, Market, etc).
To start, first, configure your Admin API Scopes:
In your Custom App, click Configure Admin API scopes.
Select all the scopes.
Once done, click Save.
Next, configure your Storefront API Scopes:
In your Custom App, click Configure Storefront API scopes.
Select all the scopes.
Once done, click Save.
Installing your Custom App to Shopify and get API Keys
When you are done setting up your API scopes, you now need to install the custom app to your Shopify Store, only then will you get your API keys.
Click Install app.
In the modal window, click Install app.
Go to API Credentials.
You will need to take note of the Admin API access token & Storefront API access token for the Shopify setup in aasaan.
You will only be able to view the Admin API access token once. So remember to store it somewhere safe or you will have to recreate and install another custom app.
