Common Odoo API Mistakes (And How to Avoid Them)

Common Odoo API Mistakes (And How to Avoid Them)

Imagine spending hours building an Odoo API integration, only to watch it fail in production because of a simple oversight—like forgetting error handling or using overly complex endpoints. Frustrating, right?

APIs are the backbone of seamless integrations, but even experienced developers make avoidable mistakes when working with Odoo’s API. Whether you’re fetching data, updating records, or automating workflows, a poorly designed API can lead to performance issues, security risks, or even system crashes.

In this guide, we’ll break down the most common Odoo API mistakes and share practical tips to keep your integrations clean, efficient, and scalable.

1. Overcomplicating API Endpoints

Mistake: Creating long, nested endpoints with unnecessary parameters.

Example of a messy endpoint: 

/api/v1/sale_orders/filter_by_date?start=2023-01-01&end=2023-12-31&status=confirmed&sort=asc

Why it’s bad:

  • Hard to maintain and debug
  • Increases the risk of errors
  • Slower performance due to excessive filtering

Solution:

  • Keep endpoints simple and RESTful (e.g., /api/sale_orders).
  • Use query parameters only when necessary.
  • Let the client handle filtering/sorting when possible.

2. Ignoring Error Handling

Mistake: Assuming API calls will always succeed. 

response = requests.get(url)  
data = response.json()  # Risky if response fails!

Why it’s bad:

  • Unhandled errors crash applications.
  • Poor user experience (no feedback on failures).

Solution:

  • Always check HTTP status codes.
  • Use try-catch blocks for graceful failures. 
try:  
    response = requests.get(url)  
    response.raise_for_status()  # Raises error for 4xx/5xx  
    data = response.json()  
except requests.exceptions.RequestException as e:  
    print(f"API Error: {e}")

3. Skipping API Documentation

Mistake: Writing code without documenting endpoints, parameters, or responses.

Why it’s bad:

  • Other developers (or future you) won’t understand how to use the API.
  • Leads to misuse, unnecessary support requests, and bugs.

Solution:

  • Use tools like Swagger/OpenAPI for auto-generated docs.
  • At minimum, maintain a simple README with:
    • Endpoint URLs
    • Required/optional parameters
    • Example requests/responses

4. Not Implementing Rate Limiting

Mistake: Allowing unlimited API calls, leading to server overload.

Why it’s bad:

  • Can crash your Odoo instance under heavy traffic.
  • Opens doors to abuse (e.g., DDoS attacks).

Solution:

  • Use Odoo’s built-in rate-limiting (e.g., --limit-request).
  • Implement throttling in your custom APIs (e.g., flask-limiter for Python).

5. Hardcoding Credentials

Mistake: Storing API keys/usernames/passwords directly in code. 

# ❌ Dangerous!  
API_USER = "admin"  
API_PASSWORD = "password123"

Why it’s bad:

  • Security risk if code is leaked.
  • Requires code changes to update credentials.

Solution:

  • Use environment variables (e.g., os.getenv("ODOO_API_KEY")).
  • Store secrets in a secure vault (e.g., AWS Secrets Manager).

6. Forgetting Pagination on Large Datasets

Mistake: Fetching 10,000 records at once. 

# ❌ Performance killer!  
orders = models.execute_kw(db, uid, password, 'sale.order', 'search_read', [[]])

Why it’s bad:

  • Slows down the server and client.
  • Can cause timeouts or memory issues.

Solution:

  • Always use pagination (offset & limit). 
orders = models.execute_kw(  
    db, uid, password,  
    'sale.order', 'search_read',  
    [[], {'offset': 0, 'limit': 100}]  # First 100 records  
)

7. Not Testing API Changes

Mistake: Deploying API updates without testing edge cases.

Why it’s bad:

  • Breaks existing integrations.
  • Leads to unexpected downtime.

Solution:

  • Write unit tests (e.g., Python’s unittest).
  • Test with:
    • Invalid inputs
    • Empty responses
    • High-load scenarios

Final Thoughts

Odoo’s API is powerful, but small mistakes can lead to big headaches. By following best practices—simplifying endpoints, handling errors, documenting properly, and securing your API—you’ll build robust, scalable integrations.
