ERP for Retail: Building Custom Solutions with NetSuite API

NetSuite API

If you’re new to NetSuite or just beginning to discover what the API can do, this article is perfect for you. The NetSuite API can be really helpful for joining things together and making your business work more automatically. But it might seem a bit scary for people who haven’t used it before. That’s why we made this guide. 

We’ll start with the simple stuff about the NetSuite API, show you how it fits into NetSuite, and give you some advice on how to set it up and use it.

What Exactly is the NetSuite API and How Does It Function?

The NetSuite API, which stands for Application Programming Interface, is a collection of protocols, routines, and tools that help to build software and applications. This API facilitates the interaction and data exchange between distinct systems by adhering to a uniform format.

The core objective behind the existence of the NetSuite API revolves around facilitating seamless integration and automation within the NetSuite platform. It provides the means for developers to gain entry to and manipulate data within the NetSuite environment. 

Additionally, it empowers the automation of various business processes and workflows. The outcome is a potential enhancement in operational efficiency, a reduction in errors, and an overall refinement in organizational efficiency.

Different Types of NetSuite API


SuiteTalk makes use of a collection of APIs (which stands for Application Programming Interfaces) that developers can use. These APIs work through a standardized method called Simple Object Access Protocol (SOAP), which is like a special way of sending and receiving data on the internet using a language called Extensible Markup Language (XML).

The main goal of SuiteTalk is to give developers the stuff they need to work with data inside NetSuite. It also helps them make things happen on their own within NetSuite, like getting work done automatically. SuiteTalk is like a powerful tool that helps connect and automate different parts of a business when using NetSuite.


SuiteScript is built using JavaScript, a common programming language that many developers are already familiar with. It enables developers to make their special scripts and functions inside NetSuite. These scripts can be set up to start running when certain things happen, like when a new record is made or when a form is submitted.

The main aim of SuiteScript is to give developers what they need to build their own unique rules inside NetSuite. It also helps them make things happen by themselves in NetSuite, like doing tasks automatically. SuiteScript is a strong tool for making the NetSuite platform even better and more capable.


RESTlet is a special tool for developers in the NetSuite platform. It’s like a server-side helper that lets developers build their connections using a style called REST (Representational State Transfer). REST is a way of designing web connections that are based on the easy-to-understand HTTP (Hypertext Transfer Protocol), and it’s built to work well and grow as needed.

The main goal of RESTlet is to give developers what they need to make special connections between NetSuite and other systems using the REST style. It’s a tool that helps build bridges between different parts, making things work together smoothly.

1. Decide Which API to Use: Choose the type of NetSuite API you need – it could be SuiteTalk, SuiteScript, or RESTlet.

2. Check Account Permissions: Make sure your NetSuite account has the necessary permissions for API usage. Usually, this means having administrative privileges.

3. Get Your Account ID: Every NetSuite account has a unique identifier called an Account ID. You can find this in the Account Preferences section of the Setup menu in NetSuite.

4. Create API Access Role: Designate a role and permission set specifically for API access. This allows you to control which users can use the API and what they can do with it.

5. Generate an API Key: An API key acts as a digital “key” to confirm your API requests. You can create one in the Integrations > Manage Integrations part of the Setup menu in NetSuite.

6. Install and Set Up Software: Depending on the type of NetSuite API you’re using, you might need to install and set up specific software or libraries. For instance, you might require a SOAP library for SuiteTalk or a JavaScript environment for SuiteScript.

7. Test Your Access: Once you’ve sorted out API access and configured any needed software or libraries, it’s a good idea to test everything. This ensures that your API access and credentials are functioning properly.

Tips and Best Practices for Using the NetSuite API

  • Navigating the realm of the NetSuite API warrants a comprehensive approach, marked by a keen awareness of nuances and strategic considerations. Unlike some accounting platforms, building a NetSuite integration demands a more intricate process due to its robust and multifaceted nature.
  • Opening a NetSuite development account comes with distinct advantages, offering a controlled environment for experimentation. However, it’s important to note that securing a license for this purpose can entail significant costs, underscoring the need for prudent resource allocation.
  • Amid NetSuite’s extensive customization capabilities lies a double-edged sword. While the flexibility to tailor the system to specific needs is undoubtedly valuable, developers must tread carefully. Striking the balance between customization and overcomplication is crucial to ensure efficient system performance.
  • Though the wealth of NetSuite API documentation lies a challenge – effectively navigating through it, this complexity can be mitigated by leveraging support resources and online communities and engaging with experienced developers to decipher the intricacies.
  • Using NetSuite “bundles” is a smart move. Imagine them like handy packages that developers use to put special changes together in a neat way. These packages can then be easily used on different accounts without too much fuss. This makes things go smoother and also makes sure that everything looks and works the same way, even in different situations.
