How do I use Javascript to send SMS using Code?

A

Hello,

 

I am trying to sent an SMS using “code by zapier” and javascript. My SMS provider tells me that I need to use this javascript code.

 

var myHeaders = new Headers();
myHeaders.append("Authorization", "Bearer <api_key>");
myHeaders.append("Content-Type", "application/json");

var raw = JSON.stringify({
  "message": "This is test and \n this is a new line",
  "to": "+35799999999999",
  "bypass_optout": true,
  "sender_id": "SMSto",
  "callback_url": "https://example.com/callback/handler"
});

var requestOptions = {
  method: 'POST',
  headers: myHeaders,
  body: raw,
  redirect: 'follow'
};

fetch("https://api.sms.to/sms/send", requestOptions)
  .then(response => response.text())
  .then(result => console.log(result))
  .catch(error => console.log('error', error));

 

But when I run this on zapier I get the following error.

 

If you are doing async (with fetch library) you need to use a callback!

 

I have no experience with javascript but I think it has something to do with the last 3 lines of this code. I searched for solutions and found a few suggestions, but I don’t know how to implement them correctly and whatever I try the error keeps changing.

 

What is the correct way of using this code to send SMS using javascript on zapier?

 

Thanks

var myHeaders = new fetch.Headers();
myHeaders.append("Authorization", "Bearer <key>");
myHeaders.append("Content-Type", "application/json");

var raw = JSON.stringify({
  "message": "message_here",
  "to": phone_here,
  "sender_id": "senderid_here"
});

var requestOptions = {
  method: 'POST',
  headers: myHeaders,
  body: raw,
  redirect: 'follow'
};

fetch("https://api.sms.to/sms/send", requestOptions)
  .then(function(res) {
    return res.text();
  })
  .then(function(body) {
   var output = {rawHTML: body};
    callback(null, output);
  })
  .catch(callback);

Hi @aristosv 

Good question.

Try using a Webhook - POST Zap action instead of a Code step.

Using a webhook will cost me an additional action. And zapier is expensive. I need to do this using code.

@aristosv 

You could use the Webhook action instead of the Code step, which would be the same amount of Tasks.

All the Code step is doing is sending a POST request.

As I mentioned, I have no experience with javascript, and I tried various suggestions I found online, but couldn’t make it work. That’s why I need help.

Hi @aristosv!

As Troy mentioned, you can use Webhooks by Zapier to do this.

Based on what you shared above, and what I found here, this is how you would set it up:

 

It looks like none of these are necessarily required:

 

You can read more about Sender ID here: https://intergo.freshdesk.com/support/solutions/articles/43000513909.

To get your API key I think you go here: https://sms.to/app#/api/client.

Hope that helps!

As I mentioned, using webhooks incurs additional cost. zapier is already comparatively expensive so I’m trying to reduce costs by using code. Never mind though, I figured it out.

var myHeaders = new fetch.Headers();
myHeaders.append("Authorization", "Bearer <key>");
myHeaders.append("Content-Type", "application/json");

var raw = JSON.stringify({
  "message": "message_here",
  "to": phone_here,
  "sender_id": "senderid_here"
});

var requestOptions = {
  method: 'POST',
  headers: myHeaders,
  body: raw,
  redirect: 'follow'
};

fetch("https://api.sms.to/sms/send", requestOptions)
  .then(function(res) {
    return res.text();
  })
  .then(function(body) {
   var output = {rawHTML: body};
    callback(null, output);
  })
  .catch(callback);

Ah, my apologies. I’m more familiar with webhooks than javascript, so I offered that. Glad you managed to figure it out, and thanks for sharing!
