AfterShip Getting Started: API Integration & First Request (2026)

Getting started overview

Integrating with AfterShip involves a series of steps designed to enable tracking, returns management, and other post-purchase functionalities for e-commerce operations. The process typically begins with creating an AfterShip account, followed by generating API keys for authentication. Developers then use these keys to make API calls, starting with basic requests like adding a tracking number to receive shipment updates. AfterShip provides API documentation and Software Development Kits (SDKs) in languages such as Node.js, Python, and PHP to facilitate integration.

The core of AfterShip's functionality revolves around its tracking capabilities, which aggregate data from over 1,000 carriers globally. This allows businesses to centralize shipment visibility and communicate delivery statuses to customers. Beyond tracking, AfterShip also offers tools for managing returns and enhancing customer engagement post-purchase, which can be integrated via its API. Initial setup focuses on establishing a secure connection and successfully submitting a tracking request.

Here's a quick reference for the initial setup:

Create an account and get keys

To begin using AfterShip, the first step is to create an account. AfterShip offers a free tier that supports up to 50 shipments per month, one user, and one store, which is suitable for initial testing and small-scale operations. Registration typically requires an email address and basic business information. After signing up, users gain access to the AfterShip admin dashboard.

Once logged into the AfterShip dashboard, an API key must be generated. This key serves as a unique identifier and authentication credential for all API requests. API keys can be found and managed within the 'Apps' or 'Settings' section of the AfterShip admin interface. Specifically, navigate to Apps > API > API Keys to generate or retrieve existing keys. It is recommended to create a new key for each application or integration to enhance security and simplify key management. Treat API keys as sensitive information, similar to passwords, and store them securely, avoiding direct exposure in client-side code or public repositories.

AfterShip API authentication primarily uses the API key in the AfterShip-API-Key header for HTTP requests. For example, a cURL request would include -H 'AfterShip-API-Key: YOUR_API_KEY'. This method ensures that only authorized applications can interact with your AfterShip account. Understanding OAuth 2.0 principles for secure API access can be beneficial for broader integration strategies, although AfterShip's primary API key method is often sufficient for direct server-to-server communication.

Your first request

After creating an account and obtaining an API key, the next step is to make your first API request. A common initial request involves adding a tracking number to AfterShip's system. This allows AfterShip to start tracking the shipment and provide status updates. This example uses the AfterShip Tracking API's /trackings endpoint to create a new tracking record.

Example: Add a Tracking Number (Node.js)

This example demonstrates how to add a tracking number using the AfterShip Node.js SDK. First, install the SDK:

npm install aftership --save

Then, create a JavaScript file (e.g., addTracking.js) with the following content:

const AfterShip = require('aftership')(process.env.AFTERSHIP_API_KEY);

async function addTracking() {
  try {
    const newTracking = {
      tracking_number: '9205590164917409267156',
      slug: 'usps',
      title: 'My First Package',
      logistics_channel_id: 'auto-detect' // Optional: Let AfterShip auto-detect carrier
    };

    const data = await AfterShip.tracking.create(newTracking);
    console.log('Tracking created successfully:', data.data.tracking);
  } catch (error) {
    console.error('Error creating tracking:', error.message);
  }
}

// Set your API key as an environment variable or replace 'process.env.AFTERSHIP_API_KEY'
// For example: export AFTERSHIP_API_KEY='YOUR_AFTERSHIP_API_KEY'
addTracking();

Replace 'YOUR_AFTERSHIP_API_KEY' with your actual API key and '9205590164917409267156' with a valid tracking number and 'usps' with the correct carrier slug, if known. Run this script using node addTracking.js to execute the request.

Example: Add a Tracking Number (cURL)

For a quick test without an SDK, you can use cURL:

curl -X POST \
  https://api.aftership.com/v4/trackings \
  -H 'AfterShip-API-Key: YOUR_AFTERSHIP_API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{
    "tracking": {
      "tracking_number": "9205590164917409267156",
      "slug": "usps",
      "title": "My First Package"
    }
  }'

Again, replace YOUR_AFTERSHIP_API_KEY and the tracking details with your specific information. A successful response will include details about the newly created tracking object.

Common next steps

Once you have successfully made your first API call to AfterShip, several common next steps can further integrate and leverage its capabilities:

1. Retrieve Tracking Details: After adding a tracking number, you will likely want to retrieve its current status and history. Use the Get a tracking endpoint, providing the tracking ID or slug and tracking number, to fetch real-time updates.
2. Configure Webhooks: To receive automatic notifications about shipment status changes without continuously polling the API, set up webhooks. AfterShip can send HTTP POST requests to a specified URL whenever events like 'in transit,' 'out for delivery,' or 'delivered' occur. This requires configuring a webhook endpoint on your server and registering it with AfterShip. Twilio's webhook security guide offers general best practices for implementing secure webhooks that apply across platforms (Twilio Webhook Security Guide).
3. Integrate with E-commerce Platforms: AfterShip offers direct integrations and plugins for popular e-commerce platforms like Shopify, Magento, and WooCommerce. These integrations often simplify the process of syncing orders and tracking information without extensive custom code.
4. Manage Returns: Explore the AfterShip Returns API to automate the returns process. This can involve generating return labels, managing return requests, and providing customers with a self-service returns portal.
5. Customize Notifications: Utilize AfterShip's notification features to send branded email or SMS updates to customers at various stages of the delivery process. This enhances the post-purchase experience and reduces customer service inquiries.
6. Error Handling and Logging: Implement robust error handling in your integration to gracefully manage API failures, rate limit issues, or invalid data. Log API requests and responses to aid in debugging and monitoring.

Troubleshooting the first call

When making your first API call to AfterShip, you might encounter issues. Here are common problems and troubleshooting steps:

• Invalid API Key:

  • Symptom: HTTP 401 Unauthorized or similar authentication error.
  • Solution: Double-check that your API key is correct and included in the AfterShip-API-Key header for cURL requests, or properly initialized with the SDK. Ensure there are no leading or trailing spaces. Verify the key's status in your AfterShip admin dashboard under Apps > API > API Keys.

• Incorrect Endpoint or Method:

  • Symptom: HTTP 404 Not Found or HTTP 405 Method Not Allowed.
  • Solution: Refer to the AfterShip API reference to confirm the correct URL endpoint (e.g., /v4/trackings) and HTTP method (e.g., POST for creating, GET for retrieving).

• Invalid Request Body:

  • Symptom: HTTP 400 Bad Request.
  • Solution: Ensure your JSON request body is well-formed and contains all required parameters, such as tracking_number and slug, if applicable. Check for typos in parameter names. The MDN Web Docs on HTTP 400 provides general information on this status code.

• Carrier Slug Issues:

  • Symptom: Tracking not found or incorrect carrier detected, even with a valid tracking number.
  • Solution: AfterShip uses specific 'slugs' for carriers (e.g., usps, fedex). If you provide a slug, ensure it's correct. You can use logistics_channel_id: 'auto-detect' to let AfterShip attempt to identify the carrier automatically. Consult the list of supported couriers in the AfterShip documentation.

• Network or Firewall Issues:

  • Symptom: Connection timeouts or inability to reach the AfterShip API server.
  • Solution: Verify your network connection. If working behind a corporate firewall, ensure that outbound connections to api.aftership.com on HTTPS (port 443) are permitted.

• Rate Limiting:

  • Symptom: HTTP 429 Too Many Requests.
  • Solution: If you are sending many requests in a short period, you might hit AfterShip's rate limits. Implement exponential backoff or ensure your application adheres to the documented rate limits.
