Understanding No Content Status (204) in Netsuite REST API Responses

When working with APIs, especially ones as complex as Netsuite's, developers often encounter various status codes that indicate the outcome of their requests. One such status is the 204 No Content, which can leave developers puzzled when they expect more feedback from their API calls. In this post, we’ll explore why you might receive a 204 status when creating a record using the Netsuite REST API, and how to effectively retrieve the ID of the created item.

The Problem: Receiving a 204 No Content Response

What Is a 204 No Content Status?

In HTTP status codes, 204 No Content indicates that the request was successfully processed, but there’s no content to return in the response body. This can be frustrating for developers who anticipate a detailed response, especially when creating records like sales orders in Netsuite.

The Challenge

If you’ve made an API call to create a sales order (or any record) using the Netsuite REST API, you may find that the response simply returns 204. This leaves you wondering: How can I retrieve the ID for the record created?

The Solution: Fetching the Created Item ID from the Response Headers

Understanding the Response Headers

The good news is that even though the body of the response is empty, the header returned in a 204 response does contain vital information. Specifically, a header called Location will include a URL pointing to the created item. This means you can leverage this URL to fetch all necessary details about the created record.

Step-by-Step Approach to Retrieve the Created Item ID

Here's how you can handle this scenario in your Python code, using the requests library effectively:

Make the API Call: When you send a POST request to create a sales order, as shown in your function, be prepared for a potential 204 response.

Check for an Empty Response: After making the POST request, check the status code of your response.

Extract the Location Header: If you receive a 204 No Content status, retrieve the Location header from the response. This should contain the URL for the created item.

Make a GET Request: Use the URL retrieved from the Location header to send a follow-up GET request to fetch the details of the newly created sales order, including its ID.

Example Code Modification

Here’s how you can modify your existing create_sales_order function to include these steps:

Conclusion

In summary, receiving a 204 No Content status from the Netsuite REST API upon successfully creating a sales order is standard behavior. Instead of being discouraged by the lack of a body response, remember that essential information lies within the response headers. By retrieving the Location header and making an additional GET request, you can easily obtain the ID of the created item and get the details you need.

With this understanding and approach, you can navigate Netsuite's API more effectively and handle responses gracefully, turning what might seem like a limitation into an opportunity for further detail retrieval.
