RPA Library : A custom Python Library for Building (RPA) bots Solutions for Partners

RPA Library is a comprehensive Python library designed to empower partners to efficiently development of Robotic Process Automation (RPA) solutions. This library provides essential functionalities and utilities, simplifying the RPA development process. This library provides a set of modules that streamline the process of automating tasks, managing inputs, logging, and interacting with web services.

Modules Overview

The RPA Library consists of several key modules, each designed to offer specific functionalities that aid in the development of RPA solutions. Below is an overview of the available modules and their primary features.

Input Module

The Input Module is designed to handle user inputs efficiently. It provides functionalities for collecting, and processing inputs from form data.

#Import the library.
from cw_rpa import Input

#Initialize the module.
input = Input()

#Calling the input method.
input.get_value("<variable name>")

E.g.
username = input.get_value("username")

Note: If the variable is missing, it defaults to None.

Logger Module

The Logger Module offers advanced logging capabilities, making it easier to track the execution flow, debug issues, and maintain operational records.

#Import the library.
from cw_rpa import Logger

#Initializing the logger
log = Logger() 

#Call log method to log in Result.txt

#To log an info message 
log.info("Logging info statement")
#To log an error message 
log.error("Logging error statement")
#To log an exception message 
log.exception("Logging exception statement")

Additionally, it supports logging warnings, critical and fatal into Result.txt

Note: A fatal log will exit the program.

#Call log method to log in result.json

#To log success message 
log.result_success_message("log success message")

#To log failure message 
log.result_failed_message ("log failed message")

Additionally import ResultLevel

from cw_rpa import Logger,ResultLevel

and use result_message to update the message level on result.json

SUCCESS 
FAILED 
ERROR 
INFO 
WARNING 

log.result_message(ResultLevel.SUCCESS,"message")
log.result_message(ResultLevel.FAILED,"message")
log.result_message(ResultLevel.ERROR,"message")
log.result_message(ResultLevel.INFO,"message")
log.result_message(ResultLevel.WARNING,"message")

#Call result_data to log the values into the data field in result.json which is used by workflow.

data_to_log = {"<key>" : <value>} #data_to_log is a json object
log.result_data(data_to_log) 

HttpClient Module

The HttpClient Module simplifies interactions with web services. It provides a straightforward way to send HTTP requests and handle responses. It Support for various HTTP methods (GET, POST, PUT, DELETE, etc.) and provides mechanisms for managing authentication tokens, essential for interacting with secured APIs.

#Import library 
from cw_rpa import httpclient

#Initialize the module.
http_client = HttpClient()

#Validate url.
http_client.validate_url("https://www.cw.com")

#Validate payload
#Ensures the payload or request body contains all necessary fields through validation.

E.g. 
request_body = {
        "accountEnabled": input.get_value("accountEnabled"), 
        "displayName": input.get_value("displayName"),
        "mailNickname": input.get_value("mailNickname")
    }

#Here, request_body must include displayName and mailNickname. Their absence will result in an error.
http_client.validate_payload(request_body, ["displayName","mailNickname" ])


#Third party integration
#Enables integration connectivity and API execution.

Syntax:

http_client.third_party_integration("<integrationName>").<method>(url=<endpoint url/api>,json=<request body>)

Benefits for Partners:

Faster Development: Pre-built components and utilities accelerate the development lifecycle.

Improved Code Quality: Standardized functions promote code maintainability and reusability.

Focus on Core Logic: Partners can concentrate on building the unique logic of their bots, leveraging the foundation provided by RPA Library.

Getting Started

To get started with the RPA Library, you need to install it in your Python environment. You can do this by installing it directly via pip.

Installation:

if hosted in public repo:

pip install cw_rpa

From wheel file:

pip install cw_rpa-0.1.0-py3-none-any

Example

Here are example demonstrating how to create the bot using the cw_rpa library:

Create O365 User Bot Sample Code:

    # import the rpa library modules
    from cw_rpa import (
        Logger, 
        ResultLevel, 
        Input, 
        HttpClient, 
    )

            userPrincipalName = input.get_value("userPrincipalName")
            new_user_payload = {
                "accountEnabled": input.get_value("accountEnabled"),  # Default value is True if not provided
