Odoo 17 is a robust ERP system that supports smooth integration with external applications through different APIs. One of the most effective methods of communicating with Odoo programmatically is through JSON-RPC (JavaScript Object Notation – Remote Procedure Call). JSON-RPC is a light, stateless protocol that supports structured requests and responses between a client and a server.

In this in-depth guide, we will take you deep into the realm of RPC Odoo 17. We will describe what JSON-RPC is, why it is useful, and how to utilize JSON RPC in Odoo 17 in your Odoo projects. Additionally, we will walk through real-life implementation using correct Odoo 17 coding practices and provide a detailed example for better understanding.

Understanding JSON-RPC

JSON-RPC is an RPC protocol encoded in JSON. It allows clients to run commands on a remote server without the need for complicated setup or communication layers. As opposed to REST APIs, which depend on pre-established HTTP verbs (GET, POST, PUT, DELETE), JSON-RPC employs a straightforward request-response model where all interactions are contained within JSON objects.

Why JSON-RPC?

JSON-RPC provides a number of benefits when implementing Odoo with external systems:

1. Lightweight and Efficient: JSON-RPC is lightweight compared to XML-RPC.
2. Uniform Structure: The format of JSON helps in easier debugging and reading.
3. Batch Processing Supported: You can send many requests in a single call.
4. Stateless Protocol: No session tracking is required, reducing complexity.
5. Language Agnostic: Works with Python, JavaScript, PHP, and many other languages.
6. Quicker Execution: As opposed to multiple requests of REST APIs, JSON-RPC achieves quicker execution with structured bulk requests.

Activating JSON-RPC in Odoo 17

You have to enable your Odoo instance’s support for remote API access first in order to be able to utilize JSON-RPC in Odoo 17. Enabling web service settings within the configuration file (odoo.conf) is needed to accomplish this.

Step 1: Enable JSON-RPC in Odoo Configuration

Modify the odoo.conf file and add the following lines:

Restart the Odoo server after making these changes.

Step 2: Implementing JSON-RPC in Odoo 17

Creating a JSON-RPC Endpoint in Odoo

We need to create a custom endpoint in Odoo that can be accessed via JSON-RPC. Here’s how you can create a controller to fetch sold products:

Python Controller Code

This controller defines an endpoint (/fetch_sold_products) that returns a JSON response containing sold product details.

Fetching Data via JSON-RPC in JavaScript

To fetch data using JSON-RPC in JavaScript, use the following Odoo module:

JavaScript Code

Rendering template code:

Real-Life Example

Suppose you operate an e-commerce site where you sell home appliances in your online store, and you want your website to dynamically display the 4 best-selling products. That is, instead of having to constantly update the product list manually, you can use JSON-RPC from the Odoo API. Now, every time a customer visits your site, the latest top-selling products are fetched automatically via JSON-RPC and displayed in real-time, improving accuracy and user experience.

Conclusion

JSON-RPC is a powerful and efficient protocol for interacting with the rpc Odoo 17. It provides a structured, lightweight, and scalable approach to performing CRUD operations, and automating processes. Using the proper implementation procedures, organizations can improve their integration capabilities and make data exchange between Odoo & third-party applications more seamless and efficient.

Additionally, through proper utilization of JSON-RPC, robust high-performing Odoo systems can be built integrating with third applications seamlessly.

Frequently Asked Questions (FAQs)

What is JSON-RPC in Odoo 17?

Odoo 17 supports JSON-RPC, a remote procedure call protocol that provides JS (JavaScript) endpoints to allow external applications to use structured JSON requests and responses to communicate with Odoo.

How to use JSON-RPC in Odoo 17?

You can get started with JSON-RPC in Odoo 17 by enabling it in the odoo.conf configuration file, and then implementing various API endpoints by creating Odoo controllers that each respond to the JSON-RPC requests.

What are the benefits of using JSON-RPC in Odoo?

Communication with Odoo using JSON-RPC is faster and more performant, enabling batch requests and allowing the protocol to avoid the overhead involved with either REST or XML-RPC.

Is JSON-RPC better than REST API in Odoo?

Although JSON-RPC may provide a more performant and structured request format for multiple records or process batch jobs, REST API, because of more widespread usage, provides a richer set of endpoints and supports a more extensive set of HTTP request methods.

How do I debug JSON-RPC calls in Odoo?

If you want to debug API calls made to Odoo JSON-RPC, you can use standard logging mechanisms in Python, browser developer tools when issuing requests from JavaScript, or tools like Postman to test JSON-RPC API requests.
