# Command prompt: Create a new Rasa project
mkdir my_rasa_project
cd my_rasa_project
rasa init

Define NLU Intents for Confluence and Jira

For our chatbot to understand user queries about Confluence pages and Jira tickets, we need to define Natural Language Understanding (NLU) intents. Provide examples of queries related to Confluence and Jira in the NLU training data. The richness of your training data directly impacts the chatbot’s ability to interpret and respond to user queries accurately. For instance, consider adding variations such as “Can you provide information on Confluence?” or “Tell me about Jira ticket statuses.” This enhances the model’s ability to generalize and accommodate different phrasings users might employ.

# YAML file representing the training data for the NLU component of a Rasa chatbot
# data/nlu.yml
version: "2.0"

nlu:
- intent: query_confluence
  examples: |
    - Tell me about Confluence
    - How can I find information on Confluence?
    - What is a Confluence page?

- intent: query_jira
  examples: |
    - How do I check my Jira tickets?
    - Tell me about Jira ticket status
    - What are my open Jira issues?

Understanding the nuances of user input is paramount. By providing a robust set of examples, you empower your chatbot to handle a wide array of queries effectively. Consider incorporating additional user personas and scenarios to ensure the versatility of your chatbot in real-world usage.

Create Custom Action for Confluence and Jira

Custom actions in Rasa allow us to extend the functionality of our chatbot. Create a custom action (actions.py) to handle queries about Confluence pages and Jira tickets. This action will interact with the respective APIs to fetch information. It’s essential to delve into the intricacies of API interactions, error handling, and response processing to ensure the reliability and resilience of your chatbot.

Expand your custom actions to handle a broader range of scenarios. For example, you can implement a response strategy for cases where Confluence pages or Jira tickets are not found. This proactive approach enhances the user experience and provides more meaningful interactions.

# Python file: Custom action for Confluence and Jira
# actions.py
import requests
from typing import Any, Text, Dict, List
from rasa_sdk import Action, Tracker
from rasa_sdk.executor import CollectingDispatcher

class ActionQueryConfluenceJira(Action):
    def name(self) -> Text:
        return "action_query_confluence_jira"

    def run(
        self, dispatcher: CollectingDispatcher, tracker: Tracker, domain: Dict[Text, Any]
    ) -> List[Dict[Text, Any]]:
        # Replace with your Confluence and Jira details
        confluence_api_url = 'YOUR_CONFLUENCE_API_URL/rest/api/content'
        jira_api_url = 'YOUR_JIRA_API_URL/rest/api/latest/issue'
        confluence_space_key = 'YOUR_CONFLUENCE_SPACE_KEY'
        personal_access_token = 'YOUR_PERSONAL_ACCESS_TOKEN'

        user_query = tracker.latest_message.get('text')
        headers = {'Authorization': f'Bearer {personal_access_token}'}

# Handle Confluence Query
        if tracker.latest_message['intent']['name'] == 'query_confluence':
            params = {'spaceKey': confluence_space_key, 'cql': 'text~"{}"'.format(user_query)}
            response = requests.get(confluence_api_url, headers=headers, params=params)
        if response.status_code == 200:
                results = response.json().get('results', [])       
        if results:
                    result = results[0]
                    title = result.get('title', 'No Title')
                    url = result.get('_links', {}).get('webui', '')
response_message =  "I found information about '{title}'. You can find it [here]({url})."
else:
 response_message = "I couldn't find any information on that topic in Confluence."
else:
 response_message = "I'm sorry, but there was an issue fetching information from Confluence." 

# Handle Jira Query
elif tracker.latest_message['intent']['name'] == 'query_jira':
 params = {'jql': 'text~"{}"'.format(user_query)}
 response = requests.get(jira_api_url, headers=headers, params=params)
if response.status_code == 200: result = response.json()
 issue_key = result.get('key', 'No Key')
 summary = result.get('fields', {}).get('summary', 'No Summary')
 response_message = f"I found information about the Jira issue '{issue_key} - {summary}'."
else:
 response_message = "I'm sorry, but there was an issue fetching information from Jira."
else:
 response_message = "I'm not sure how to handle that query."
 dispatcher.utter_message(response_message)
return []

Continuously refine and expand these actions to cater to evolving user needs and new integration possibilities.
