shopify-gql-helper 0.1.2

Tiny, production-minded helper for the Shopify Admin GraphQL API

Shopify GraphQL Helper

Tiny, production‑minded helpers for the Shopify Admin GraphQL API. Shopify's official Python SDK exposes GraphQL().execute only; this package adds sessions, automatic cursor pagination, and per‑shop throttling.

Features:

• 🚀 Simple, focused API for Shopify GraphQL Admin API
• 🔄 Automatic cursor-based pagination
• ⚡ Built-in request throttling
• 🔒 Thread-safe implementation
• 🧩 Transport layer abstraction

Note: This is not an official Shopify package.

Installation

pip install shopify-gql-helper

Quickstart

query = """
query ($first:Int!, $after:String) {
  products(first:$first, after:$after, query:"status:ACTIVE") {
    pageInfo { hasNextPage endCursor }
    nodes { id legacyResourceId title handle }
  }
}
"""

from shopify_gql_helper import ShopifySession, execute, cursor_pages

session = ShopifySession("https://example.myshopify.com", "shpca_123")

# One-off request
data = execute(session, query, {"first": 1})

# Stream all products
for product in cursor_pages(session, query, ["data", "products"]):
    print(product["id"], product["title"])

connection_path lists the keys from the response root to the desired connection, so ["data", "products"] points to data.products above. Additional GraphQL variables can be supplied via the optional variables argument.

Throttling

Shopify uses a leaky bucket policy. ShopifySession coordinates requests per shop through a shared ThrottleController. Adjust min_bucket (default 50) and min_sleep (default 1.0s) to tune how aggressively you consume the bucket. Reuse a single ShopifySession per shop to avoid fighting the throttling limits.

Configuration

ShopifySession

from shopify_gql_helper import ShopifySession

# Required parameters
session = ShopifySession(
    shop_url="https://your-store.myshopify.com",
    access_token="shpca_your_access_token"
)

# Optional parameters
session = ShopifySession(
    shop_url="https://your-store.myshopify.com",
    access_token="shpca_your_access_token",
    api_version="2025-01",  # default
    min_bucket=50,          # minimum available requests before throttling
    min_sleep=1.0,          # minimum sleep time between requests (seconds)
)

Throttling

Shopify uses a leaky bucket policy. ShopifySession coordinates requests per shop through a shared ThrottleController.

Important: Reuse a single ShopifySession per shop to properly respect rate limits.

Custom Transport

You can provide a custom transport that implements the Transport protocol:

from shopify_gql_helper.transport import Transport

class CustomTransport(Transport):
    def post(self, url: str, headers: dict, json: dict, timeout: float):
        raise NotImplementedError

Development

# Install with development dependencies
pip install -e ".[dev]"

# Run tests
pytest

# Run with coverage
pytest --cov=shopify_gql_helper

Limitations / Roadmap

• Bulk operations
• Nested pagination (e.g., products → variants)
