The NetXL API is a powerful set of tools that allow you to automate key interactions, these include getting real-time pricing and stock availability, requesting quotes, and creating and confirming orders

The API is free and available to all customers, however to create an order you are required to have a credit account, payment via PayPal and Credit/Debit card is not currently supported via the API

The documentation below will show how to get the most out of the API, it includes code samples in several popular programming languages, it also includes guides on using the API with several popular GUI based tools, perfect for customers with less development experience

Getting Started

First things first, in order to use the API you will need to create a key, we use this to identify the requests you make as coming from your account, this ensures we return the correct information to you, and means only you can see your pricing and order data

To create a key, visit the preferences section of the NetXL customer dashboard

Your API key is unique to your account, you should not share it with anyone you do not trust, you can disable it at any time or create a new key from the preferences page

Accessing the API

There are two ways to access the API, the most common is to build an integration using a programming language such as Python or Java, this allows you to automate calls to the API tightly integrating into existing systems

The other way is to use a graphical tool such as Postman or Paw (or even a Web Browser), this method lets you query the API for data on an ad-hoc basis, without any need for computer programming experience

Response Data Formats - JSON & CSV

By default the API will return all responses in JSON format, this is the best format for automated integrations, however, it is also human readable due to its structured layout and key/value structure, an example response for the /customer command is shown on the right

Several API commands support returning the response as a CSV file, this is useful for customers who wish to import the data into a third party such as Microsoft Excel or Google Sheets, how to return a CSV is explained below, additionally, requests made from the Web Browser will return a CSV by default, making it easy for you to add a link to get updated pricing or order information


Your First Request

Now we have an API key and have decided how to access the API (programmatically or with a tool) it's time to make our first request.

The NetXL API is a RESTful API, it supports operations on the following object types, Customer, Address, Order, and Quote, the base URL for the API is shown on the right.

For the first request, we'll ask the API to return our customer information, this includes our name and email address, plus details of any credit account we hold.

NetXL API Endpoint

Authenticating your API requests

For every request you need to provide the API key as a form of authentication, there are two ways to do this, you can use either way regardless of how you're accessing the API

  1. Supply the key as a HTTP Header in the request
  2. Use a Query String in the URL to provide it

Provide the key as a HTTP header

To provide the API key as an extra HTTP header, include the following header in your HTTP requests

X-Api-Key: <your-api-key>

Provide the key using a query string

Providing the API key using a query string is a simple as appending the following key/value to the end of every URL you're making requests to


Query String Example

Selecting the response type

Some API commands support returning the response as a CSV file, useful for importing into third party application such as Microsoft Excel or Google Sheets

To request the response as a CSV file you should set the 'Accept' header on your request to `text/csv` as follows

Accept: text/csv

All other requests should send the `Accept` header as `application/json` if you omit the header you will get JSON responses back by default, it is recommend to set the header on every request however to avoid any confusion if future commands have a different default response format

Making the request

Now that you have everything setup, its time to make the first API request, we have two blog posts that show complete examples of calling the API using a programming language (Python) and a graphical tool (Postman)

  1. Read the Python API example
  2. Read the Postman API example

GET /customer

Log in to try the API commands


Error Handling

There are multiple situations where the API might return an error, most errors are caused by invalid data being provide to endpoints when asking to create objects. Consult the returned message to see why the command failed, you should also double check the documentation for the command in question to ensure the right data is being provided.

In rare cases, the API can fail due to an issue such as a issue with a server, or some third party the service relies on. In most of these cases you'll not be able to fix the issue

In all error cases, the response HTTP status code will be set, helping you to better understand the cause of the error

Possible HTTP Error Codes

In the event of an error, the API will return one of the following error codes, in most cases a 4xx error can be fixed by adjust the command, a 5xx error can't

400 Bad Request

Indicates that the API could not complete the request, check the response message for the cause of the error

401 Unauthorized

Your API key is not valid, please check it and try again

402 Payment Required

404 Not Found

This indicates either the URL was not valid, or the object you requested does not exist, for example trying to query an invalid order reference

409 Conflict

Upon confirming your order, the response will include an order ID and reference from NetXL, these can be used to query the order or when contacting NetXL for assistance

PUT /order/<confirmation-code>


Understanding Auto Confirmation

When creating an order, it is possible to skip the confirmation stage by setting `auto_confirm` to true in the original request.

In order to use auto confirmation, you must send a shipping_method parameter in your request, or have set a default shipping method in the NetXL dashboard

Invalid Shipping Method

If the shipping method you provided is not valid for this order, you will receive an error response. You can see the valid shipping methods by disabling auto confirmation and creating and confirming the order as normal.


Auto confirmed orders will use the current live price for each item, this may be more or less than the previous price paid for an item. NetXL will not provide refunds for differences in price where an item has increased when auto confirmation is used, you may however still cancel an order prior to shipping

Cancel or Amend Order

To cancel or make changes to an order, please raise a support ticket or call 0330 043 3000 for assistance

Requesting a Quote

To request a quote for an order, send your POST request to /quote instead of /order, this will raise a ticket with NetXL customer support who will then create a quote for the requested items.

You will be notified via email once the quote is created, you can confirm the order using the confirmation code as normal, but with the adjusted pricing
