What Is the ShipStation API?

At its core, an API (Application Programming Interface) is a set of rules and protocols that allows different software applications to communicate with each other. The shipstation api is a robust, reliable interface built for developers to programmatically interact with the ShipStation platform, extending its core functionality to fit unique business needs.

ShipStation currently provides two primary API offerings that are gradually converging into a single, enhanced experience:

  1. ShipStation Companion API: This is the API designed to be used in conjunction with the powerful features you already get from the main ShipStation application. Think of it as a way to enhance and automate your existing workflow. If you use the ShipStation app to manage your shipping but need to programmatically pull order data or push tracking information to another system, the shipstation companion api is your go-to tool.
  2. Standalone ShipStation API (formerly ShipEngine): For those seeking a complete, end-to-end shipping solution that can be embedded directly into their own platform or application, this is the API to use. Recently rebranded from ShipEngine, this powerful ship station api provides the industry’s richest developer functionality without requiring the use of the ShipStation user interface.

For the purpose of advanced customization within an existing ShipStation workflow, this guide will primarily focus on the capabilities of the companion api shipstation.

Exploring Core ShipStation API Features

The true power of the API lies in its granular control over virtually every aspect of the shipping process. By interacting with specific endpoints, you can build sophisticated shipstation automations that perfectly match your operational model.

Here are some of the key shipstation api features:

  • Orders API: The shipstation order api allows you to do more than just import orders. You can create, retrieve, update, and manage orders from any source, making it perfect for integrating with custom storefronts, ERPs, or internal order management systems. You can programmatically create a manual batch order in shipstation or use the API to shipstation api create order endpoints for individual fulfillment requests.
  • Rates API: Go beyond simple rate shopping. With the Rates API, you can build custom carrier selection logic to automatically find the most cost-effective service for every single shipment based on your own business rules, saving significant money over time.
  • Labels API: Streamline your fulfillment by creating outbound and return shipping labels individually or in large batches. This endpoint is essential for high-volume shippers who need to generate labels without manual intervention in the ShipStation app.
  • Tracking API: Keep your customers informed every step of the way. The shipstation tracking api provides real-time tracking events for shipments. You can combine this with a shipstation webhook, which can push tracking updates to your systems automatically, triggering branded notifications and enhancing the post-purchase experience.
  • Inventory API: Maintain accurate stock levels across all your selling channels. The shipstation inventory api allows you to sync your inventory from a central source of truth, like a WMS or ERP, directly with ShipStation, preventing overselling and ensuring data consistency.
  • Customs API: Simplify the complexities of global ecommerce. This API helps you programmatically provide all necessary customs information for international shipments, including generating commercial invoices and other documentation to avoid delays at the border. This is invaluable for businesses shipping to regions like shipstation germany or anywhere else in the world.
  • Address Validation API: Reduce delivery failures and costly returns. Before a label is even created, you can use the API to validate shipping addresses, ensuring accuracy and improving your delivery success rate.

Getting Started: Your First Steps with the API

Ready to start building? Getting access to the ShipStation API is a straightforward process. Here’s what you need to do to begin your journey with advanced customization.

First, you’ll need a shipstation developer account, which is simply your standard ShipStation account. From there, you can generate your API credentials. The process for how to get shipstation api key and secret is simple:

  1. Log in to your ShipStation account.
  2. Navigate to Settings > Account > API Settings.
  3. Click the "Generate New API Keys" button if no keys are present. Your API Key and API Secret will be displayed.

These credentials are used for shipstation api authorization on all your requests, so be sure to keep them secure and never expose them in client-side code.

For developers who want to test their integrations without affecting live orders, ShipStation offers a shipstation sandbox account. This testing environment allows you to experiment with the API’s full functionality safely.

To ensure you have everything you need, ShipStation provides extensive shipstation api documentation. This resource is essential for any developer and includes detailed information on endpoints, parameters, and request/response formats. You can also find valuable information in the legacy shipengine api docs, which can be useful context given the platform’s history. This comprehensive ship engine api documentation serves as the ultimate shipstation api reference for building your integrations.

Advanced Customization with Practical API Examples

This is where theory meets practice. The shipstation developer api allows for nearly limitless shipstation automation possibilities that extend far beyond the in-app automation rules.

Here are a few examples of what you can build:

  • Integrate with Custom Hardware: If you use specialized warehouse hardware like shipstation dimensioners, you can use the API to automatically pull weight and dimensions from a shipstation dimensioner and apply them to an order. This eliminates manual data entry and ensures precise rate calculations every time.
  • Build Bespoke System Connections: Many businesses use proprietary or niche software, like a custom CRM or ERP. The shipstation api integration capabilities allow you to create a seamless, two-way sync. You could, for example, build shipstation highrise integrations to sync customer shipping history directly into your CRM profiles.
  • Advanced Order Routing: Imagine you have multiple warehouses. With the shipstation rest api, you can build a script that routes orders to the nearest fulfillment center based on the customer’s location and real-time inventory levels pulled from your WMS, a level of logic more advanced than standard rules.
  • Developing with Your Favorite Tools: The API is flexible. You can use tools like Postman to test endpoints (shipstation api postman). For a real-world application, a simple shipstation api php example could involve a script that queries for newly shipped orders and updates a master sales spreadsheet.

Here is a conceptual look at what a request might look like:

// Fictional PHP example for fetching orders
$apiKey = 'YOUR_API_KEY';
$apiSecret = 'YOUR_API_SECRET';
$credentials = base64_encode("$apiKey:$apiSecret");

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://ssapi.shipstation.com/orders?orderStatus=awaiting_shipment");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Authorization: Basic $credentials"));
$response = curl_exec($ch);
curl_close($ch);


$orders = json_decode($response);
// Now you can process the orders

These shipstation api examples only scratch the surface of what’s possible with the API, including the evolving capabilities of shipstation api v2.

API Best Practices: Rate Limits and Support

To ensure system stability for all users, ShipStation enforces a shipstation api rate limit. This limit is typically 40 requests per minute, per set of API credentials. It’s crucial to design your application to respect this limit by queuing requests or using bulk endpoints where possible to avoid hitting the ceiling.

If you encounter issues or have questions, the first place to turn is the official shipstation api docs. They are comprehensive and cover most use cases. For more complex problems, you can reach out to shipstation api support through the standard support channels available to you based on your plan level. The developer community is also a great resource for seeing how others have solved similar challenges.

By combining the power of the ShipStation platform with the flexibility of its API, you can build a shipping and fulfillment workflow that is truly optimized for your business.
