Shopify API: what it is and what it's for
The Shopify API lets external systems read and write store data, such as products, orders, and customers.
Summary
What matters before moving forward.
- Shopify exposes a REST API and a GraphQL API to access store data programmatically.
- It's the foundation of any custom integration: ERPs, external apps, automations.
- Access is controlled by scopes, an integration only sees the data it has explicit permission for.
What it's used for in practice
Without an API, any sync between a Shopify store and another system, such as an ERP, CRM, or invoicing tool, would have to be done by hand.
With the API, an external system reads new orders, updates stock, or creates products directly, without manual intervention.
REST vs GraphQL
The REST API exposes one endpoint per resource, such as products, orders, or customers. The GraphQL API lets you request exactly the fields you need in a single call.
For integrations that only need a few specific fields, GraphQL usually reduces the number of requests made to the server.

Frequently asked questions
Common questions about this topic.
Do I need the Shopify API if I only use App Store apps?
Not directly, apps already use the API behind the scenes. You only need to work with it directly for custom integrations that no app already covers.
