Currently trying to create a Whatsapp message to be sent via This custom Javascript code on Zapier shown via Twilio API. It successfully reaches out to twilio but returns "Authentication Error - No credentials provided".

var messagesUrl = "/<accountSID>/Messages.json";
var payload = {
 "To": "whatsapp:<tonumber>",
 "Body" : "Hey This is a test",
  "From" : "whatsapp:<fromnumber>"
};
 var options = {
 "method" : "post",
 "payload" : payload
};

options.headers = {
 "Authorization" : "Basic <accountsid>:<accounttoken>"
};
fetch(messagesUrl, {options, body: JSON.stringify(payload)})
 .then(function(binaryResponse) {
  return binaryResponse.json();
})
.then(function(jsonResponse){
  callback(null, {result: jsonResponse});
}).catch(callback);

What is the best approach to take to simply send a confirmation text on whatsapp to prospects on zapier? Thanks in advance

fetch takes an options object as its second argument. You're currently doing:

fetch (messagesUrl, {
  options: {
    method: 'post',
    payload: payload,
    headers: {
      Authorization: '...'
    }
  },
  body: JSON.stringify(payload)
}) // ...

You shouldn't have a nested option object. Assuming the twilio stuff is set up correctly (I have no idea), this should work:

fetch (messagesUrl, {
  method: 'post',
  payload: payload, // probably remove this, it's not part of the syntax (see below)
  headers: {
    Authorization: '...'
  }
  body: JSON.stringify(payload)
}) // ...

all options you can pass to the second argument: https://developer.mozilla/en-US/docs/Web/API/WindowOrWorkerGlobalScope/fetch#Syntax

Thank you for your help, i ended up solving this by using a much simpler Custom web hook POST method, i was over-plicating it. Details on how i did this for anybody else wanting to send whats-app messages through Twilio on Zapier Below:

Method

Post

URL

https://api.twilio./2010-04-01/Accounts/<accountSID>/Messages.json

Data

To=whatsapp:%2B<toNumber>&From=whatsapp:%2B<fromNumber>&Body=Put your message body here

Note: The + of your E.164 number will concatenate hence the %2B to replace it

Basic Auth

<AccountSID>|<AccountToken>

Headers

Content-Type | application/x-www-form-urlencoded

I found this post very very interesting. I also use ZAPIER and TWILIO and I would like to have a customer who registers on my googlesheet receive a confirmation whatsapp message.

I can't configure ZAPIER. I did a lot of tests but I don't understand much about programming and I certainly made a mistake.

When I launch the test from ZAPIER it gives me this error: The request could not be sent to Webhooks by Zapier. The app returned "A 'To' phone number is required.".

I have attached the image with the inserted configuration. Where did I go wrong? How should I correct it?

UPDATE: my approved template on whatsapp is this:

Ciao {{1}}, la tua registrazione è avvenuta con successo.
Ricordati che lo SCONTO che hai scelto è attivo fino al {{2}}. 
Ti aspettiamo - nei prossimi giorni - nel tuo Centro LIGHT di fiducia.

Nell'attesa ti facciamo ancora i migliori Auguri
