In NetSuite, a Digital Certificate is primarily used for secure communication between NetSuite and external systems. It ensures encrypted data transfer and provides authentication for integrations, particularly when using Web Services, RESTlets, and SuiteTalk APIs.
Key Use Cases for Digital Certificates in NetSuite
- Secure API Integration
- Used to authenticate RESTlet and SuiteTalk (SOAP-based) integrations.
- Enables encrypted communication using protocols like HTTPS and OAuth 2.0.
- Single Sign-On (SSO)
- Supports SAML 2.0 for secure SSO implementations.
- Ensures users are authenticated securely via identity providers (IdPs).
- Payment Gateway Integration
- Ensures secure data exchange with payment gateways and financial institutions.
- Email Security (SPF, DKIM)
- Supports digitally signed emails to prevent phishing and spoofing.
- SuiteSignOn Authentication
- Provides secure authentication for third-party applications via SuiteSignOn.
Implementing Digital Certificates in NetSuite
1. Generating a Certificate
- Create a Private Key and a Certificate Signing Request (CSR) using OpenSSL or similar tools.
- Submit the CSR to a Certificate Authority (CA) to obtain a Signed Certificate.
2. Uploading the Certificate in NetSuite
- Navigate to File Cabinet
- Go to Documents > Files > File Cabinet.
- Upload the certificate file and private key securely.
- Associate with Integration Records
- Go to Setup > Integration > Manage Integrations > New.
- Use the certificate file for OAuth 2.0 authentication setup.
3. Configuring OAuth 2.0 Integration
- Go to Setup > Users/Roles > Access Tokens > New Access Token.
- Generate tokens tied to the integration record.
- Utilize the certificate for authentication during API requests.
