Introduction
Integrating external APIs into NetSuite SuiteScript requires careful planning to ensure security, performance, and error handling. This article explains best practices for API requests in fulfillment processing.
Common Challenges in NetSuite API Integration
- Rate Limits → Many third-party APIs limit requests per minute.
- Response Parsing → API responses may contain nested JSON data.
- Retry Mechanisms → Network failures can impact data integrity.
Best Practices for Handling API Requests in SuiteScript
1. Implementing Efficient API Calls with Error Handling
External data from Dispatch Tracker is retrieved using REST-based API calls. To avoid script failures, try/catch blocks and response validation are essential.
const fetchDispatchTrackerData = (orderId) => {
try {
let response = jjConfig.getOrderDetails(orderId);
if (response.status !== 200 || !response.service_orders.length) {
throw new Error(`Invalid response received: ${JSON.stringify(response)}`);
}
return response.service_orders[0].status;
} catch (error) {
log.error(“Error in fetchDispatchTrackerData”, error);
return null;
}
};
2. Implementing API Request Retry Logic
Sometimes API calls fail due to network latency or server errors. Implementing a retry mechanism ensures the request completes successfully.
const fetchWithRetry = (orderId, retries = 3) => {
for (let attempt = 0; attempt < retries; attempt++) {
let status = fetchDispatchTrackerData(orderId);
if (status) return status;
log.audit(`Retrying API request (${attempt + 1}/${retries}) for orderId ${orderId}`);
sleep(2000); // Delay before retrying
}
log.error(`Failed to retrieve Dispatch Tracker data after ${retries} attempts.`);
return null;
};
3. Secure Handling of API Credentials
API authentication tokens should never be hardcoded. Instead, use NetSuite’s script parameters for secure retrieval.
const API_KEY = runtime.getCurrentScript().getParameter(“custscript_dt_api_key”);
4. JSON Data Normalization for NetSuite Processing
APIs often return nested JSON structures that may need flattening for NetSuite.
const normalizeApiResponse = (response) => { return { orderId: response.service_orders[0]?.order_id || “”, status: response.service_orders[0]?.status || “Unknown”, scheduledDate: response.service_orders[0]?.scheduled_at || “” }; };
Conclusion
By implementing secure, efficient API requests, developers can seamlessly update NetSuite Item Fulfillment statuses, ensuring accurate order tracking across external systems.
