Why the Odoo 19 API is a Game-Changer for Integrations

For years, developers working with Odoo had to contend with XML-RPC for programmatic interactions. While functional, it often presented a steep learning curve, requiring specific XML structures and authentication flows that felt somewhat dated in an increasingly RESTful world. Odoo 19 changes all of this.

The introduction of a native, token-based API is a significant leap forward. Here’s why it’s generating so much excitement:

1. Simplified Authentication: Gone are the days of session management complexities. The Odoo 19 API leverages API keys, acting as Bearer tokens. This streamlined approach makes securing your requests much easier and more intuitive, aligning with modern API security practices.
2. Enhanced Security: API keys can be generated with specific expiration dates and revoked as needed, providing granular control over access. This drastically reduces the attack surface compared to sharing user credentials.
3. Modern Development Experience: The new API feels much more like a standard RESTful API, making it more approachable for developers familiar with contemporary web services. This reduces development time and overhead for integration projects.
4. Improved Performance (Potentially): While the underlying Odoo ORM remains, the simplified request structure can lead to more efficient communication, especially when dealing with high volumes of data.
5. Built-in Documentation: Odoo 19 includes comprehensive, automatically generated API documentation directly accessible from your instance (typically at /doc). This invaluable resource details all available models, methods, and fields, making discovery and implementation a breeze. This integrated documentation is a massive win for productivity, allowing developers to quickly understand the structure and capabilities of each Odoo model.

The transition to this modern Odoo API signifies Odoo’s commitment to empowering developers with robust and developer-friendly tools. It truly revolutionizes how you can build Odoo 19 integrations with external systems, opening up a world of possibilities for automation and data synchronization.

Prerequisites for This Odoo 19 API Tutorial

Before we dive into the code, ensure you have the following set up:

• An Odoo 19 Instance: Make sure you have a running Odoo 19 server. This tutorial will not work with older Odoo versions due to the API changes.
• Python 3: The examples will be in Python. Any recent version of Python 3 should work.
• requests Library: This powerful HTTP library simplifies making web requests in Python. Install it if you haven’t already:

pip install requests

Step-by-Step Guide: Using the Odoo 19 API with Python

Let’s begin our practical journey into the Odoo 19 API Tutorial.

Step 1: Generating Your Odoo 19 API Key

The first crucial step is to obtain an API key from your Odoo 19 instance. This key will authenticate your requests and grant access to the data you need.

1. Log in to Odoo 19: Access your Odoo 19 instance as a user with sufficient permissions (e.g., an administrator or a user specifically created for API access).
2. Navigate to User Preferences: Click on your username in the top-right corner of the Odoo interface, then select “My Profile” or “Preferences”.
3. Access the Security Section: Within your user preferences, look for a tab or section labeled “Security”.
4. Generate API Key: In the “API Keys” subsection, click the “Generate API Key” button. Odoo will prompt you to enter your current password to confirm your identity.
5. Configure and Copy:
   • Provide a descriptive name for your API key (e.g., “Integration with External App,” “API Tutorial Key”).
   • Optionally, set an expiration date. For production environments, it’s highly recommended to set an appropriate expiration policy. For this tutorial, you might set it for a day or a few hours.
   • Click “Generate”. Odoo will display your new API key. Crucially, copy this key immediately. Odoo will only show it to you once. If you lose it, you’ll need to generate a new one.

Security Best Practice: Treat your Odoo API key with the same level of security as you would your password. Never hardcode it directly into public repositories or share it unnecessarily. Consider using environment variables or a secure configuration management system.

Step 2: Setting Up Your Python Environment

Create a new Python file (e.g., odoo_api_client.py) and import the necessary libraries.

import requests
import json

Step 3: Base Configuration for Odoo 19 API Calls

Define your Odoo instance’s base URL, database name, and the API key you just generated.

# Replace with your actual API key generated in Odoo 19
api_key = "YOUR_ODOO_API_KEY_HERE"

# Replace with your Odoo instance URL (e.g., "http://localhost:8069" or "https://mycompany.odoo.com")
base_url = "YOUR_ODOO_INSTANCE_URL"

# Replace with your Odoo database name (if applicable, often not needed for /api/ endpoints directly)
database_name = "YOUR_ODOO_DATABASE_NAME"

# Define standard headers for all API requests
headers = {
    "Content-Type": "application/json",
    "Authorization": f"Bearer {api_key}" # This is the crucial part for token-based authentication
}

Note: For the new /api/ endpoints in Odoo 19, the database_name is typically handled by the Odoo server routing or via URL prefix, and not always needed explicitly in the request body for standard operations. However, for some scenarios or older Odoo APIs, it might still be relevant. For simplicity with the new API, we’ll focus on the base_url and api_key.

Step 4: Reading Data: The search_read Method

The search_read method is your go-to for fetching records from an Odoo model, combining the filtering capabilities of search with the data retrieval of read. Unlike the search method, which only returns a list of record IDs, search_read directly provides the actual field values for the matching records.

Let’s retrieve some contact information from the res.partner model.

# Function to handle API requests
def make_api_request(method, endpoint, payload):
    url = f"{base_url}/api/{endpoint}"
    try:
        response = requests.post(url, headers=headers, data=json.dumps(payload))
        response.raise_for_status()  # Raise HTTPError for bad responses (4xx or 5xx)
        return response.json()
    except requests.exceptions.RequestException as e:
        print(f"Error during API call to {url}: {e}")
        if response is not None:
            print(f"Response status code: {response.status_code}")
            print(f"Response content: {response.text}")
        return None

print("--- Reading Data (Search and Read) ---")
search_read_payload = {
    "model": "res.partner",
    "domain": [], # An empty domain [] retrieves all records. You can add filters like [["is_company", "=", True]]
    "fields": ["id", "display_name", "name", "email"] # Specify the fields you want to retrieve
}

contacts = make_api_request("POST", "search_read", search_read_payload)
if contacts:
    print("Successfully retrieved contacts:")
    print(json.dumps(contacts, indent=4))
    # Let's save the ID of the first contact for later updates/deletions
    if contacts and len(contacts) > 0:
        first_contact_id = contacts[0]['id']
        print(f"\nFirst contact ID for demonstration: {first_contact_id}")
    else:
        first_contact_id = None
        print("\nNo contacts found for further demonstration.")
else:
    first_contact_id = None
    print("Failed to retrieve contacts.")

# Internal Link Example: For more advanced filtering, check out our guide on [Optimizing Odoo Domains](/blog/optimizing-odoo-domains-for-performance).

• endpoint: search_read is the method to use.
• model: Specifies the Odoo model (e.g., res.partner for contacts, project.task for tasks).
• domain: This is Odoo’s powerful filtering mechanism. An empty list [] means no filters, returning all records (within access rights). You could add a domain like [["is_company", "=", True]] to fetch only companies.
• fields: A list of strings specifying which fields you want in the response. This helps reduce network traffic and response size. If not specified, Odoo will return a default set of fields.

This foundational method is key to extracting information from your Odoo 19 instance.

Step 5: Creating Data: The create Method

Adding new records to Odoo is just as straightforward with the create method. You simply provide the model and a dictionary of values for the new record.

print("\n--- Creating Data (Create) ---")
create_payload = {
    "model": "res.partner",
    "values": {
        "name": "Odoo 19 API Demo Contact",
        "email": "odoo19.api.demo@example.com",
        "phone": "123-456-7890",
        "is_company": True # Example: Create a company contact
    }
}

new_contact_data = make_api_request("POST", "create", create_payload)
if new_contact_data and 'id' in new_contact_data:
    new_record_id = new_contact_data['id']
    print(f"Successfully created contact with ID: {new_record_id}")
else:
    new_record_id = None
    print("Failed to create new contact.")

• endpoint: create.
• model: The target Odoo model.
• values: A dictionary where keys are field names and values are the data for the new record. Ensure you provide all required fields for the model, otherwise, the operation will fail.

Step 6: Updating Data: The write Method

Modifying existing records is handled by the write method. You’ll need the ID of the record(s) you wish to update and the new values.

print("\n--- Updating Data (Write) ---")
if new_record_id: # Use the ID of the contact we just created
    update_payload = {
        "model": "res.partner",
        "ids": [new_record_id], # A list of IDs to update
        "values": {
            "email": f"updated.odoo19.api.demo.{new_record_id}@example.com",
            "comment": "Updated via Odoo 19 API Tutorial"
        }
    }

    update_result = make_api_request("POST", "write", update_payload)
    if update_result == True: # Odoo API returns True on successful write
        print(f"Successfully updated contact with ID: {new_record_id}")
    else:
        print(f"Failed to update contact with ID: {new_record_id}. Result: {update_result}")
else:
    print("No new contact ID available to demonstrate update operation.")

• endpoint: write.
• model: The target Odoo model.
• ids: A list of integer IDs of the records to be updated.
• values: A dictionary containing the fields to be updated and their new values. The Odoo 19 API will only update the fields specified here.

Step 7: Deleting Data: The unlink Method

When it’s time to remove records, the unlink method comes into play. Provide the model and a list of IDs to delete. Exercise caution with this operation, as deletions are permanent!

print("\n--- Deleting Data (Unlink) ---")
if new_record_id: # Use the ID of the contact we created (and potentially updated)
    delete_payload = {
        "model": "res.partner",
        "ids": [new_record_id] # A list of IDs to delete
    }

    delete_result = make_api_request("POST", "unlink", delete_payload)
    if delete_result == True: # Odoo API returns True on successful unlink
        print(f"Successfully deleted contact with ID: {new_record_id}")
    else:
        print(f"Failed to delete contact with ID: {new_record_id}. Result: {delete_result}")
else:
    print("No new contact ID available to demonstrate delete operation.")

• endpoint: unlink.
• model: The target Odoo model.
• ids: A list of integer IDs of the records to be deleted.

Advanced Tips & Best Practices for Your Odoo 19 API Integrations

Beyond the basic CRUD operations, consider these crucial tips to ensure your Odoo API integrations are robust, secure, and performant.

1. Robust Error Handling

The provided examples include basic try...except blocks for requests.exceptions.RequestException. In a production environment, you should expand on this:

• HTTP Status Codes: Differentiate between 401 Unauthorized, 403 Forbidden, 404 Not Found, 500 Internal Server Error, etc.
• Odoo Specific Errors: The Odoo API will often return specific error messages within the JSON response (e.g., validation errors). Parse the response.json() for error or message keys to get detailed feedback.
• Retry Mechanisms: Implement exponential backoff for transient errors (e.g., network glitches or temporary service unavailability).

2. API Key Management and Security

• Environment Variables: Never hardcode your Odoo 19 API Tutorial API keys directly into your scripts. Use environment variables (e.g., os.getenv("ODOO_API_KEY")) or a secure vault system.
• Least Privilege: Generate API keys with only the necessary access rights for the specific tasks they need to perform. Do not use an administrator’s API key for routine integrations if a more restricted user will suffice.
• Expiration and Rotation: Set expiration dates for your API keys and have a strategy for regular rotation to minimize the impact of a compromised key.
• IP Whitelisting: If your Odoo instance supports it, restrict API key usage to specific IP addresses.

3. Efficient Data Retrieval with Domains and Fields

• Targeted Domains: Avoid fetching all records with an empty domain ([]) when you only need a subset. Use specific Odoo domain filters (e.g., [["create_date", ">=", "2023-01-01"]]) to fetch only relevant data. This significantly reduces data transfer and processing load on both ends.
• Select Specific Fields: Always specify the fields you need. Do not fetch all fields if you only require a few. This optimizes bandwidth and parsing time, especially for models with many fields.

4. Exploring the Odoo API Documentation (/doc)

One of the most valuable aspects of the new Odoo 19 API is its built-in, real-time documentation.

• Accessing Documentation: Simply navigate to YOUR_ODOO_INSTANCE_URL/doc in your browser. This will present you with an interactive API reference, listing all available models and their methods.
• Model and Field Discovery: Use this documentation to understand the exact names of models (e.g., res.partner, product.template, sale.order) and their fields, as well as the parameters expected by different methods. It’s an indispensable tool for Odoo development.
• Testing: Some documentation interfaces even allow you to try out API calls directly from the browser, which is fantastic for quick tests and debugging.

5. Rate Limiting Considerations

While Odoo’s internal API typically doesn’t have strict rate limits for self-hosted instances, if you’re using Odoo.com or a heavily loaded server, be mindful of the frequency of your requests.

• Batch Operations: Where possible, combine multiple create/update operations into a single API call if the Odoo API method supports it (e.g., providing multiple ids for write or unlink).
• Throttling: Implement delays between consecutive API calls if you’re making a large volume of requests to avoid overwhelming the server or hitting potential limits.

6. Leveraging Other Odoo Resources

To further enhance your Odoo 19 API Tutorial knowledge, explore the official Odoo documentation for developers: Odoo Developer Documentation. Also, delve into the Python requests library documentation for more advanced HTTP client features: Requests Library.
