SuiteScript RESTlets

Using RESTlets

SuiteScript RESTlets create custom REST APIs for NetSuite.

Introduction to SuiteScript RESTlets

SuiteScript RESTlets allow developers to create custom RESTful web services within the NetSuite environment. They provide a flexible way to expose business logic to external applications and systems. RESTlets are particularly useful for integrating NetSuite with other platforms, automating processes, and enhancing system capabilities.

Setting Up a RESTlet in NetSuite

To set up a RESTlet in NetSuite, you'll need to create a new SuiteScript file and define the desired REST API endpoints. RESTlets can handle HTTP requests such as GET, POST, PUT, and DELETE. These requests map to functions in your SuiteScript code.

Deploying Your RESTlet

Once your RESTlet script is ready, you need to deploy it within NetSuite. To do this, navigate to Setup > Customization > Scripts > New. Upload your SuiteScript file and configure the deployment settings, such as assigning a script ID and setting the status to 'Released'.

Consuming the RESTlet API

After deployment, the RESTlet can be accessed via its URL. Make sure to include authentication details as required by NetSuite. Here’s an example of how you might use a RESTlet from an external application using a GET request:

Best Practices for RESTlets

When developing RESTlets, consider the following best practices:

  • Security: Always secure your RESTlets using NetSuite’s authentication mechanisms.
  • Performance: Optimize your scripts to handle large data volumes efficiently.
  • Error Handling: Implement comprehensive error handling to manage potential issues gracefully.
  • Documentation: Thoroughly document your RESTlet endpoints and their usage for future reference and maintenance.
