🧰 How to Get Started with the ShipStation API

Step 1: Create Your API Keys

1. Log in to your ShipStation account
2. Go to Account Settings → API Settings
3. Generate your API Key and API Secret

Step 2: Make Your First API Call

Use any HTTP client (like Postman, Curl, or a backend language like Python, Node.js, or PHP).
Example request (GET orders):

These can help speed up development and error handling.

🔐 Authentication: Simple and Secure

ShipStation uses Basic Auth with a Base64-encoded API key and secret. You don’t need OAuth unless you’re building for third-party users.

Quick Tip:

Use environment variables to store your credentials securely and avoid hardcoding them in scripts.

✅ Real-World Use Cases

📦 Use Case 1: Automate Label Generation

An online store gets 200+ orders daily. Instead of printing labels manually, a backend cron job fetches new orders every hour, generates labels, and sends PDFs to a print queue.

🌎 Use Case 2: Sync Multi-Channel Orders

A business sells on Etsy, Shopify, and Amazon. Using the API, they pull all orders into one dashboard and fulfill from a central warehouse with unified tracking.

🧾 Use Case 3: Export Reports and Analytics

An e-commerce analyst uses the API to export order and shipment data daily into Google Sheets or a BI dashboard for performance tracking.
