Create a flow to check upcoming holidays

In this first segment, we request you to provide the month and region for which you would like to retrieve upcoming holidays. By entering the month and region, we can tailor the holiday information specifically to your preferences. Here, we are using Forms to get user inputs.

1. In the flows page, from the Actions pane, drag and drop the INPUT CAPTURE node into the editor space of the Designer tab.
2. Double-click the dropped Input capture node, and you will notice the Input Capture Details form.
3. Configure node in the following way:
   • Name: holidaysForm
   • Drag the DROP DOWN component in the form designer and configure it with the following details:
     • Switch the Required toggle button
     • Name: country
     • Label: 'Please select the country' (please include the single quotes)
     • How many options you want?: 2
     • Option 1 name and value: India
     • Option 2 name and value: USA
     • In the form designer, click SAVE to save the DROP DOWN component details.

       

   • Drag and drop the RADIO BUTTON component and configure it with the following details:
     • Name: month

     • Label: 'Please select the month you are interested in'

       Note: Include either single or double straight quotes, and avoid using curly quotes.

     • How many radio buttons you want ?: 12
     • Option 1 Name: Jan
     • Option 1 Value: Jan
     • similarly, for Option 2 to Option 12, enter the name and value for other months as Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec, respectively.
     • In the form designer, click SAVE to save the Radio Button component details of the Input Capture node.
   • Form Submit Button: Submit
4. In the Input Capture node, click SAVE to save the Input Capture node details.
5. Now, connect the holidaysForm INPUT CAPTURE node to the START node, and click SAVE in the Designer tab.

Now that we have the month and region you selected, we will process this data to retrieve the upcoming holidays using our Holidays API. The API will provide us with a comprehensive list of holidays based on your chosen criteria. This ensures that you receive accurate and up-to-date details about the upcoming holidays in your desired month and region.

1. In the Designer tab, drag and drop the HTTP node and configure it the following details:
   • Name: holidaysList

   • URL: 'http://elasticsearch-es-http:9200/holidays/_search?size=10000&pretty'

     Note: In the above URL, you can replace the "holidays" with the collection name created in the ingest data page. Also, make sure to include single or double straight quotes.

   • Method: Get

   • Body:

     {
       "_source": [
         "Month",
         "Date",
         "Holiday Name"
       ],
       "query": {
         "bool": {
           "must": [
             {
               "match": {
                 "Region": "holidaysForm.country"
               }
             },
             {
               "match": {
                 "Month": "holidaysForm.month"
               }
             }
           ]
         }
       }
     }

     • In the above code, "_source": ["Month","Date","Holiday Name"] this line specifies the fields that should be included in the search results. In this case, it includes the fields "Month," "Date," and "Holiday Name."
     • "query": {"bool": {"must": [{"match": {"Region": "holidaysForm.country"}}, {"match": {"Month": "holidaysForm.month"}}]}} This part defines the query for Elasticsearch to retrieve the desired data. It uses a "bool" query, which allows for combining multiple conditions. In this case, the "bool" query contains a "must" clause, which specifies that both conditions must match.
     • Overall, this query is designed to retrieve documents that match specific conditions, including matching the region and month specified in the "holidaysForm" variables or parameters. The "_source" section indicates the desired fields to be included in the search results or retrieved data.
   • Click SAVE to save HTTP node configurations.

     

2. In the Designer tab, connect the holidaysList HTTP node to the holidaysForm Input Capture node.
3. Drag and drop the EXPR node, and double-click the EXPR node.
4. In the Expression Details form, configure the following details:
   • Name: holidaysAvailabilityCheck
   • Expression: holidaysList["hits"]["total"].value == 0
   • Is Branching required?: Yes
   • How many branches required?: 2
   • Enter branch names with comma separator?: true,false
   • In the Expression Details form, click SAVE to save the EXPR node details and navigate back to designer pane.

     

5. Similarly, connect the holidaysAvailabilityCheck EXPR node to the holidaysList HTTP node, and in the designer tab, save the flow.

Once we've gathered the holiday data from the API, we will display it in the chatbot for your convenience. You'll be able to view a comprehensive list of upcoming holidays, complete with their dates. This will give you a clear overview of the holidays you can look forward to in your selected month and region. If the response contains list of holidays, then we can process the output using the Script node and display the results. Otherwise, we can display the message stating that there is no holiday for the specific month and you can restart the flow.

1. In the Designer tab, drag and drop the SCRIPT node, and configure with the following details:
   • Name: holidaysListProcessing

   • Script:

     var result = "Following holidays are available for the month of "+holidaysForm.month+" in "+holidaysForm.country+":";
     var count = 1; 
     for (var i=0;i<holidaysList["hits"]["total"].value;i++) 
     { 
     result = result+"\n\n"+count+") **"+holidaysList["hits"]["hits"][i]["_source"].Date+"** - "+holidaysList["hits"]["hits"][i]["_source"]["Holiday Name"]; count = count + 1; 
     }

   • in the Script details form, click SAVE to save the Script node configurations.
2. Connect the holidaysListProcessing Script node with the holidaysAvailabilityCheck EXPR node under false connection point.
3. Now, drag and drop the TEXT node to format the output of script. Double-click the text node and configure the following:
   • Name: showHolidays

   • Text Message: holidaysListProcessing

     Note: Here we are calling the "holidaysListProcessing" script node as value in the Text node. We can use the node name as variable to use a previous node response.

4. In the Text details form, click SAVE to save the Text node details, and connect the showHolidays TEXT node to the holidaysListProcessing SCRIPT node.
5. For the no holiday list, drag and drop a TEXT node and configure with the following details:
   • Name: holidaysNAMessage

   • Text Message: "Holidays are not available for the month of "+holidaysForm.month+" in "+holidaysForm.country+"."

     Note: Include either single or double straight quotes, and avoid using curly quotes.

   • In the Text Details form, click SAVE to save the Text node details.
6. In the Designer tab, connect the holidaysNAMessage Text node to the holidaysAvailabilityCheck EXPR node's true connection point, and click SAVE in the designer pane to save the overall flow.
