REST APIs with Python requests

Modern Oracle EBS implementations rarely operate in isolation. Organizations frequently integrate Oracle EBS with Oracle Integration Cloud (OIC), Oracle APEX, Salesforce, e-commerce platforms, third-party logistics providers, banking applications, and other enterprise systems. Most of these integrations rely on REST APIs to exchange data securely and efficiently.

Python’s requests library makes it easy to consume REST APIs, send and receive JSON data, authenticate using API tokens or OAuth, and automate business processes. Whether you’re retrieving customer information, creating sales orders, updating inventory, or calling Oracle Integration Cloud services, the requests library provides a simple and reliable way to integrate Oracle EBS with external applications.

In this guide, you’ll learn how to use the requests library for Python Automation in Oracle EBS, including authentication methods, REST API operations, error handling, and real-world Oracle EBS integration examples.


What is the requests Library?

REST API Methods

The requests library is one of the most popular Python packages for making HTTP requests. It simplifies communication with RESTful web services by allowing developers to send HTTP requests such as GET, POST, PUT, PATCH, and DELETE with just a few lines of code.

Instead of dealing with low-level networking, the library handles connection management, headers, authentication, cookies, SSL certificates, and JSON serialization automatically.

For Oracle EBS developers, requests is the preferred library for integrating Python applications with REST APIs exposed by Oracle EBS, Oracle Integration Cloud (OIC), Oracle APEX, and third-party enterprise systems.


Why Use requests with Oracle EBS?

REST APIs have become the standard method for integrating enterprise applications. Rather than exchanging CSV files or relying on manual imports, Oracle EBS can communicate with external systems in real time.

Common Oracle EBS integration scenarios include:

IntegrationExample
Oracle Integration Cloud (OIC)Invoke integrations from Python
Oracle APEXSubmit or retrieve application data
SalesforceSynchronize customers and opportunities
ShopifyImport online orders
Payment GatewayProcess payment confirmations
Logistics ProviderTrack shipment status
CRM SystemUpdate customer information
HR SystemSynchronize employee records

Benefits

  • Real-time integrations
  • Reduced manual effort
  • Faster data synchronization
  • Secure communication using HTTPS
  • JSON support
  • Easy authentication
  • Seamless cloud integration

Installing the requests Library

Install the library using pip:

Python
pip install requests
Python

Verify the installation:

Python
import requests

print(requests.__version__)
Python

Understanding HTTP Methods

REST APIs use different HTTP methods depending on the operation.

MethodPurposeOracle EBS Example
GETRetrieve dataGet customer details
POSTCreate dataCreate sales order
PUTUpdate a recordUpdate supplier information
PATCHUpdate selected fieldsChange order status
DELETERemove a recordDelete temporary data

Sending Your First GET Request

A GET request retrieves information from an API.

Python
import requests

url = "https://enodeas.com/api/customers"

response = requests.get(url)

print(response.status_code)
print(response.json())
Python

In Oracle EBS, this could be used to retrieve customer, supplier, or inventory information from a REST service.


Sending a POST Request

POST requests are commonly used to create new records.

Python
import requests

url = "https://enodeas.com/api/orders"

payload = {
    "customer":"ABC Corporation",
    "item":"Laptop",
    "quantity":5
}

response = requests.post(url, json=payload)

print(response.status_code)
Python

This approach is commonly used when creating sales orders or submitting transactions to Oracle Integration Cloud.


Working with JSON Data

Most Oracle REST APIs exchange data using JSON.

Example response:

Python
{
  "customerNumber":"1001",
  "customerName":"ABC Corporation",
  "country":"Germany"
}
Python

Access values easily:

Python
data = response.json()

print(data["customerName"])
Python

Authentication Methods

Enterprise REST APIs are secured using authentication mechanisms.

Common authentication methods include:

  • Basic Authentication
  • Bearer Token
  • OAuth 2.0
  • API Keys

Example:

Python
headers = {
    "Authorization":"Bearer YOUR_ACCESS_TOKEN"
}

response = requests.get(url, headers=headers)
Python

Never hard-code credentials in production scripts. Use environment variables or a secure secrets manager.


Oracle EBS Use Case: Calling Oracle Integration Cloud (OIC)

Business Requirement

Whenever a new customer is approved in Oracle EBS, an Oracle Integration Cloud process should synchronize the customer with Salesforce.

Workflow:

Oracle EBS
      ↓
Python
      ↓
requests Library
      ↓
Oracle Integration Cloud
      ↓
Salesforce

Python sends the customer data as a JSON payload to the OIC endpoint, which performs the required transformations and forwards the information to Salesforce.


Oracle EBS Use Case: Retrieving Shipment Status

A logistics provider exposes a REST API that returns shipment updates.

Python can:

  1. Call the logistics API.
  2. Parse the JSON response.
  3. Update Oracle EBS shipment tables.
  4. Notify customer service if a shipment is delayed.

This approach provides near real-time visibility without manual tracking.


Oracle EBS Use Case: Creating Sales Orders

A web storefront receives online orders throughout the day.

Instead of uploading CSV files, Python can:

  • Read the order details.
  • Validate mandatory fields.
  • Send the order to an Oracle EBS REST API.
  • Receive the order number in the response.
  • Log successful and failed transactions.

This enables seamless order processing with minimal manual intervention.


Handling Errors

Network interruptions, authentication failures, or invalid payloads can cause REST API calls to fail.

Use exception handling to manage these situations gracefully:

Python
import requests

try:
    response = requests.get(url, timeout=30)
    response.raise_for_status()
except requests.exceptions.RequestException as error:
    print(error)
Python

Proper error handling helps create more reliable automation scripts.


Best Practices

  • Use HTTPS for all API communication.
  • Store credentials securely.
  • Validate request payloads before sending them.
  • Log requests and responses for troubleshooting.
  • Implement retries for temporary failures.
  • Set appropriate timeout values.
  • Avoid exposing sensitive information in logs.
  • Separate API logic into reusable functions or modules.

Common Challenges

Network timeoutsConfigure retries and timeouts
Invalid JSONValidate payloads before sending
SSL certificate issuesUse trusted certificates and proper verification
Rate limitsThrottle requests and implement backoff strategies
