FedEx Open Shipment API Label Authentication: A Primer

Before diving into the implementation details, it’s essential to understand the concept of label authentication. FedEx Open Shipment API Label Authentication is a two-step process that ensures the legitimacy and security of your shipping labels.

Step 1: Authentication Request

To initiate the authentication process, you need to send an authentication request to the FedEx API. This request includes your API credentials, such as your FedEx account number, meter number, and API key.

POST /oauth/token HTTP/1.1
Host: oauth2.fedex.com
Content-Type: application/x-www-form-urlencoded

grant_type=client_credentials&client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET

Step 2: Token Generation

Upon receiving the authentication request, the FedEx API generates an access token, which is a unique, time-limited token used to authenticate your API requests.

HTTP/1.1 200 OK
Content-Type: application/json

{
  "access_token": "YOUR_ACCESS_TOKEN",
  "token_type": "bearer",
  "expires_in": 3600
}

Implementing FedEx Open Shipment API Label Authentication

Now that we’ve covered the basics, let’s explore the implementation details. We’ll focus on generating a shipping label using the FedEx Open Shipment API, with label authentication.

Step 1: Set up Your API Credentials

Create a FedEx developer account and obtain your API credentials, including your client ID, client secret, and API key.

Credential	Description
Client ID	Your unique FedEx developer account ID
Client Secret	Your secret key used for authentication
API Key	Your unique API key used for label generation

Step 2: Authenticate and Generate an Access Token

Use your API credentials to authenticate and generate an access token. You can use any programming language to make the API request.

import requests

auth_url = "https://oauth2.fedex.com/v1/oauth/token"
client_id = "YOUR_CLIENT_ID"
client_secret = "YOUR_CLIENT_SECRET"

response = requests.post(auth_url, data={
    "grant_type": "client_credentials",
    "client_id": client_id,
    "client_secret": client_secret
})

access_token = response.json()["access_token"]

Step 3: Generate a Shipping Label

Using the access token, generate a shipping label by making a POST request to the FedEx Open Shipment API.

import requests

label_url = "https://api.fedex.com/ship/v1/label"
access_token = "YOUR_ACCESS_TOKEN"

response = requests.post(label_url, headers={
    "Authorization": f"Bearer {access_token}",
    "Content-Type": "application/json"
}, json={
    "shipment": {
        "shipper": {
            "name": "John Doe",
            "address": {
                "street Lines": ["123 Main St"],
                "city": "Memphis",
                "state": "TN",
                "postalCode": "38101",
                "countryCode": "US"
            }
        },
        "recipient": {
            "name": "Jane Doe",
            "address": {
                "streetLines": ["456 Elm St"],
                "city": "Los Angeles",
                "state": "CA",
                "postalCode": "90012",
                "countryCode": "US"
            }
        },
        "serviceType": "FEDEX_GROUND",
        "packageDetails": {
            "weight": {
                "units": "LB",
                "value": 10.0
            },
            "dimensions": {
                "length": 10.0,
                "width": 10.0,
                "height": 5.0
            }
        }
    }
})

label_response = response.json()
label_url = label_response["label"]["url"]

Step 4: Download the Shipping Label

Finally, download the shipping label from the generated URL.

import requests

response = requests.get(label_url, stream=True)

with open("shipping_label.pdf", "wb") as f:
    for chunk in response.iter_content(chunk_size=1024):
        if chunk:
            f.write(chunk)
