Shopify API authentication uses OAuth for app installations. Generate access tokens through your app's admin panel, then include the token in request headers. Both GraphQL Admin API and REST Admin API require the same OAuth credentials, supporting API version 2025-10 and later.

GraphQL Admin API lets you request only the data you need in a single query, reducing bandwidth. REST Admin API uses traditional endpoint-based requests. Both access the same store data; choose GraphQL for efficiency or REST for simpler integrations with existing tools.

Register webhooks in your app's admin settings to subscribe to store events like order creation or product updates. Shopify sends JSON payloads to your endpoint when events occur. Handle webhook verification, validate signatures, and store event data to trigger downstream workflows.

Yes, Storefront API provides public access to product and cart data for custom shopping experiences outside the Shopify admin. Use it with fetch or axios in JavaScript to query products, manage carts, and create checkout flows without exposing sensitive store data.

Shopify implements rate limiting on API calls; Admin APIs use bucket-based limits while Storefront API has per-IP thresholds. Monitor response headers for remaining quota. Implement exponential backoff and request batching to stay within limits when polling frequently.

Check HTTP status codes and JSON error responses to identify issues like authentication failures or rate limiting. Implement retry logic with exponential backoff for 429 responses. Log errors and validate input data before requests to reduce failures in production.
