HI @SreenadhChenna ,
I trust you are doing great

1. Identify the APIs: Determine the REST APIs provided by both applications that need to be integrated. These APIs should allow you to exchange data and perform operations on the respective applications.

2. Authenticate and authorize: Understand the authentication and authorization mechanisms used by both applications. Ensure you have the necessary credentials or tokens to authenticate and access the APIs.

3. Design the integration flow: Plan how data will flow between the two applications. Decide which application will initiate the integration and define the triggers or events that will initiate data exchange.

4. Implement the integration: Write code to interact with the REST APIs of both applications. You can use programming languages such as JavaScript, Python, or Java to make HTTP requests to the APIs. Use libraries or frameworks specific to your chosen programming language for ease of integration.

5. Handle data transformation: Depending on the data formats used by each application, you may need to transform data from one format to another before sending or receiving it. Use appropriate libraries or tools to handle data transformation tasks.

6. Secure data transmission: Ensure that data transmitted between the applications is encrypted and transmitted over secure channels (e.g., HTTPS) to protect sensitive information.

7. Error handling and logging: Implement error handling mechanisms to handle failures or exceptions during the integration process. Log relevant information for troubleshooting and monitoring purposes.

8. Test and validate: Thoroughly test the integration to ensure it functions as expected. Validate that data is correctly exchanged between the applications in both directions.

import requests

url = "https://api.example.com/endpoint"
headers = {"Content-Type": "application/json"}
data = {
    "key1": "value1",
    "key2": "value2"
}

response = requests.post(url, json=data, headers=headers)
if response.status_code == 200:
    # Successful API call
    print("API call succeeded")
    response_data = response.json()
    # Process the response data
else:
    # API call failed
    print(f"API call failed with status code: {response.status_code}")
    print(response.text)
