I'm writing a program in Node.js to create a WhatsApp chatbot that sends a List messages based on the different information to users. This is the desired Output:

I'm trying to find a way where I don't need to hard code the row titles for different list messages every time and the method should automatically generate this part

{"title":"row 1 title"}, {"title":"row 2 title"} .... {"title":"row n title"}

I wrote a method that takes an array of title values as an argument and generates a list based on that. But the message is not sent and I don't see any errors. I'm using WATI API as my whatsapp provider.

1. 

   Any help or advice is appreciated!.

   Refer to this answer How do I create dynamic list using WhatsApp API? Create the genJSON() function as suggested.

   This is just an example, you can invoke the function as per your requirement

   method.js

   const WA = require("./whatsapp")
   
   function genJSON() {
     var arr = ['row 1', 'row 2', 'row3']
     try {
       let d = []
       for (const row of arr) {
         d.push({
           title: row
         })
       }
       console.log(d)
   WA.sendListInteractive (d, whatsapp_number)
   
     } catch (e) {
       console.log(e)
     }
   }
   genJSON()
   

   modified whatsapp.js

   const sendListInteractive = async (jsonData, senderID) => {
           data = []
           var options = {
               'method': 'POST',
               'url': 'https://'   process.env.URL   '/api/v1/sendInteractiveListMessage?whatsappNumber='   senderID,
               'headers': {
                   'Authorization': process.env.API,
                   'Content-Type': 'application/json',
               },
               body: JSON.stringify({
                   "header": "", //optional
                   "body": "Body",
                   "footer": "", //optional
                   "buttonText": "Button Text",
                   "sections": [
                       {
                           "title": "string",
                           "rows": jsonData //changes
                       }
                   ]
               })
       
           };
           request(options, function (error, response) {
               if (error) console.log(error);
               console.log(response.body);
           });
       }
