The NetXL API is a powerful set of tools that allows 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 but 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 and 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 which 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, which 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, which is the best format for automated integrations. 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, which 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 and you can use either method 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 as 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 applications 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, but it is recommended to set the header on every request This avoids any confusion if future commands have a different default response format

Making the request

Now that you have everything setup, it's 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

Error Handling

There are multiple situations where the API might return an error. Most errors are caused by invalid data being provided 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 e.g. 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 adjusting the command, but a 5xx error can not

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

Insufficient available credit on your account.

404 Not Found

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

409 Conflict

The request could not be processed as it would cause duplicated data to be created. Check the response message for details.

429 Too Many Requests

Your request to the API have been rate limited. Please wait 5 minutes and try your command again.

500 Internal Server Error

An unexpected error occurred in the API. You should try your API command again or contact support for assistance.

503 Service Unavailable

The API is temporarily unavailable. Try your command again in a few minutes.

504 Gateway Timeout

A third party service the API relies on is unavailable. Try your command again in a few minutes.

Error Body Response
  • message string

    Indicates what caused the returned error, especially useful for diagnosing 4xx errors

POST /order

400 Bad Request

Rate Limiting

The number of requests you can send to the API is limited. This is to ensure system stability and performance of the service. If you exceed the limit you will receive a 429 HTTP status code response and you should retry your command after a short delay.

Order and Quote commands are not rate limited.

This would query all switches with more than 16 PoE ports.

A list of attributes and their types can be obtained using the attribute list command

GET /product?Range (ft)>=300,Range (ft)<=400


Orders and Quotes

The API allows you to query your order history. Credit account customers can create orders using their credit limit.

There are two ways to create an order. The first is a two-step process where the order must be confirmed using a secondary API call. The other is a single call that will create and confirm the order in one go. Use this second method when you do not require pricing or shipping quotes.

    Shipping address to use for the order. You can provide either the full address, or the ID of an existing address.

Example Order Object

Creating an order

To create an order, you need to provide two key things to the API:

  1. A list of Item SKU's and quantities you wish to order
  2. The billing and shipping addresses

Additionally, if using auto confirmation, you will be required to provide a shipping method, or to set a default method in the NetXL dashboard.

Providing the item list

For each item you wish to order, you are required to provide the SKU and the quantity of units required. SKU's can be obtained using the product catalogue search or from the NetXL website.

Billing & Shipping Addresses

For the addresses, you can either provide the full address details, or use an existing address by providing it's ID. If you provide both the details and an ID, then the ID will take priority and the details will be ignored

Optional Additional Parameters

You may provide the following additional parameters with your order request:

  1. customer_reference: Your reference for this order
  2. auto_confirm: Should this order be automatically confirmed
  3. shipping_method: The shipping method to use for this order

POST /order

Order Created Successfully

Confirming an Order

Once you have created an order, you can check the pricing and shipping costs. If you're happy with these, you can use the confirmation_code provided to confirm the order. It is at this point that your order will be placed and entered into our fulfilment queue.

Confirming the order

To confirm the order, you need to provide a shipping method. Alternatively, you can use your account default, provided the default method was returned in the shipping_options field when creating the order

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 a default shipping method set 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, though you may 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.

POST /quote
