Given the importance of real-time data, and the amount of resources that can be saved by eliminating manual data, it’s no surprise that NetSuite users would want to connect their system with other critical tools. This article explains just how they can do that, by shedding light on NetSuite’s API, its types and how businesses can make the most of it.Â
What is NetSuite API? What does it do?
NetSuite API (Application Programming Interface) is a way for different systems to talk to NetSuite, like how your phone syncs with your smartwatch. It matters because businesses work with multiple tools (ecommerce platforms, CRMs, shipping software), and without integration they are all working in silos and you’re stuck with manual data entry, errors, and wasted time.Â
Types Of NetSuite API Integrations
NetSuite offers three main ways to connect with external applications and automate processes:
- NetSuite SOAP API (SuiteTalk SOAP Web Services)
- NetSuite REST API (SuiteTalk REST Web Services)
- SuiteScript & RESTlet
Each method has its strengths, so choosing the right one depends on your needs. Let’s break them down.
1. NetSuite SOAP API (SuiteTalk SOAP Web Services)
This is NetSuite’s oldest and most reliable API, built on SOAP (Simple Object Access Protocol). It provides a structured and well-documented way to interact with the NetSuite platform.
Key Features:
- Full Access: Supports almost all records in NetSuite.
- Stable & Well-Supported: Been around for years, making it a trusted choice.
- Handles Bulk Data: Great for large-scale data transfers.
- Strong Security: Uses OAuth and Token-Based Authentication (TBA).
- Best for: Large integrations, bulk data processing, and enterprise applications.
Limitations:
- Complex Setup: Uses WSDL files and XML, which require technical expertise.
- Slower Performance: SOAP-based requests are larger and take more processing time.
2. NetSuite REST API (SuiteTalk REST Web Services)Â
NetSuite’s REST API is newer and still evolving. It was designed to be simpler and more modern than SOAP, but because it’s in beta, it still has limitations.
Key Features:
- Easier to Use: Uses JSON instead of XML.
- Better for Web & Mobile Apps: More lightweight than SOAP.
- Standard REST Format: Makes integration smoother with modern systems.
- Best for: Simple real-time transactions and web/mobile applications.
Limitations:
- Not Fully Developed: Many features and records are still missing.
- HATEOAS Model: Requires multiple requests to fetch related data.
- Not Ideal for Bulk Operations: Slower when dealing with large datasets.
3. SuiteScript & RESTlet
This is not a standard API but a way to create custom scripts within NetSuite to handle automation and data exchange.
SuiteScript is NetSuite’s scripting language, built on JavaScript. It allows developers to customize and automate processes within NetSuite. A RESTlet is a SuiteScript function that acts as a custom REST API endpoint. It allows external applications to interact with NetSuite by sending and receiving data in JSON format.Â
Best for: custom integrations, internal automation, and lightweight API needs.
SuiteScript (For Internal Automation)
- Custom Workflows & Processes: Automate NetSuite tasks.
- JavaScript-Based: Easy for NetSuite developers familiar with JS.Â
RESTlet (For External Integration)
- Acts as a Custom API: Can be built for specific business needs.
- More Flexible than NetSuite’s REST API: Faster and more efficient.
- Uses JSON: Easier to integrate with web and mobile apps.
Limitations:
- Requires Development Effort: You need to write custom scripts.
- Limited to One NetSuite Account: Can’t easily manage multiple instances.
How Businesses Can Leverage NetSuite APIs
Organizations use NetSuite APIs to streamline operations, improve efficiency, and integrate various business systems. Here are some key use cases of NetSuite APIs:
1. Keeping Data in Sync Across Platforms
Manually updating customer details, orders, and inventory across different software applications can be a hassle. With NetSuite APIs, businesses can automatically sync data between NetSuite and tools like Salesforce, Microsoft Dynamics, or other CRMs. This ensures that customer records, sales transactions, and account updates stay consistent everywhere without human effort.Â
For instance, if a sales rep updates a customer’s details in a CRM, the API can instantly update the same information in NetSuite’s finance module. No duplicate entries, no errors, no delays.
2. Creating Custom Reports and Insights
Every business tracks different success metrics. NetSuite APIs allow companies to extract and analyze data in their own way, creating reports tailored to their needs.
3. Connecting Online Stores with NetSuite
eCommerce businesses rely on seamless integrations between their online stores and backend systems. NetSuite APIs help sync orders, payments, inventory, and shipping details between platforms like Shopify, Magento, or WooCommerce.
For example, when a client places an order on a Shopify store, the API updates stock levels in NetSuite, triggers an invoice, and notifies the shipping team, all automatically.Â
4. Automating Everyday Business Tasks
Repetitive tasks like invoice generation, purchase approvals, and data validation can slow down operations. NetSuite APIs enable automation, making workflows faster and error-free.
For instance, a company can set up an API-driven process where invoices over a certain amount are automatically flagged for approval. Instead of employees manually tracking these, the system handles it, saving time and improving efficiency.
5. Developing Custom Mobile Apps
For teams that need access to NetSuite data on the go, developers can use the REST API to build mobile apps. These apps let employees perform tasks like checking inventory, updating orders, or managing customer details directly from their phones.
For example, a field sales team can use a mobile app to create customer orders instantly without waiting to get back to the office. This flexibility ensures smooth operations no matter where employees are.Â
How NetSuite API Integration Solves Real Business Problems
In a distribution or manufacturing business, efficiency is everything. Without integration, employees are stuck manually transferring data between platforms, leading to:
- Duplicate entries – Sales reps update orders in the CRM, but finance teams don’t see the changes in NetSuite ERP.
- Processing delays – Inventory isn’t updated in real-time, leading to stockouts or overselling.
- Data errors – Manual data entry increases the risk of typos, incorrect pricing, or missing details.Â
A well-integrated system eliminates these issues, allowing businesses to scale without operational headaches. For example:Â
- For a distributor managing thousands of SKUs, keeping inventory updated across different platforms is a challenge. With NetSuite API integration, stock levels are updated with real-time visibility, preventing overselling or stockouts.
- For a manufacturer processing high-volume B2B orders, automating workflows like invoicing, approvals, and shipments ensures that large orders move smoothly through the system.
- For a finance team, syncing NetSuite with payment processors eliminates the hassle of manually reconciling transactions, reducing errors and saving hours of work.
NetSuite is already the backbone of your business processes. But when integrated properly, it becomes even more powerful, connecting every part of your business for seamless, automated, and scalable growth. Whether you’re processing orders faster, eliminating errors, or improving customer experience, NetSuite API integration ensures that every system works together to drive efficiency and success.Â
