Payments Apps API reference

Anchor to AuthenticationAuthentication

All Payments Apps API requests require a valid Shopify access token.

Public and custom apps created in the Partner Dashboard generate tokens using OAuth. Include your token as a X-Shopify-Access-Token header on all API requests.

To keep the platform secure, payments apps need to request specific access scopes during the install process. Only request as much data access as your app needs to work.

All requests to the Payments Apps API must be authenticated. Learn more about getting started with authentication and building payments apps.

Anchor to GraphQL endpointGraphQL endpoint

The Payments Apps API is available at a single GraphQL POST endpoint:

https://{shop_domain}/payments_apps/api/2025-10/graphql.json

You can access the Payments Apps API using curl or any HTTP client.

Anchor to VersioningVersioning

The Payments Apps API is a versioned API. Updates are released quarterly. To keep your app stable, make sure that you specify a supported version in the URL.

Anchor to Usage limitationsUsage limitations
