Serverless Phone Verification with Twilio Verify and Twilio Functions - twilio

I am trying to implement the project from https://www.twilio.com/blog/serverless-phone-verification to verify phone number using SMS TOTP.
When I created new function the url given by Twilio Functions is https://isabelline-badger-5492.twil.io/sendTOTP
I have given the VERIFY_SERVICE_SID env variable to point to correct value ‘VAxxxxxxx’.
But I am getting error as below. Please advise what is wrong.
The Verify functions works fine by itself, but when triggered from Functions, it throws below error.
{
"success": false,
"message": {
"status": 404,
"message": "The requested resource /Services/VAxxxxxxx/Verifications was not found",
"code": 20404,
"moreInfo": "https://www.twilio.com/docs/errors/20404"
}
}

Make sure the Twilio helper library your Twilio Functions are using is up to date (3.29.2 is to old to use this newer feature). If using the Console based functions, you can find and set the version here, for twilio. Make sure to click save. The latest helper library version as of this response is 3.37.1. This will fix the issue.

Get Customer Input block throws error when using Lex as customer input

I am trying to configure lex bot in AWS Connect. I have created a demo Lex bot that is working fine in Lex but after integrating it with Aws Connect in the Get Customer Input block in the contact flow, it throws an error.
I have checked the error in CloudWatch and you can see the error following:
{
"Results": "Error",
"ContactId": "contactId",
"ContactFlowId": "COntactFlowId",
"ContactFlowName": "TalkToOctaveAgent2",
"ContactFlowModuleType": "GetUserInput",
"Timestamp": "2022-03-25T05:30:08.252Z"
}
I can't recognize where this error comes from. I have set lex intents in the Get Customer Input block with proper names as in Lex. Please let me know how I can resolve this error.

How do I get twilio 5 digit error code for a failed voice call?

We have a callback url in place that is correctly capturing the failed status of a call.
Our code then fetches from twilio the details of the call by doing the following:
$call = $twilio_client->calls($sid)->fetch();
Within the call details returned there is no 5 digit error code listed, even though the failed status is present.
How do we get the 5 digit error code that caused the failure?
Twilio developer evangelist here.
Thanks to #miknik for the answer, however that is actually a deprecated resource (which is why you can't currently find any documentation on the matter). It's taken me a while to find the answer as I've been chasing down where the notifications have gone.
The Notifications API was deprecated in favour of the Monitor Alerts API. This API can give you all the details about an alert, including the 5 digit code.
The best way to receive these alerts for your application is to set up a webhook in your account console which will send all the parameters about the alert as part of the request.
You can also list your alerts which will allow you to find alerts from a specific resource SID (in your case, a call SID).
Let me know if this helps at all.
Make an authenticated GET request to
/2010-04-01/Accounts/{AccountNumber}/Calls/{CallSid}/Notifications
So in PHP the following will retrieve the notification info for your call
$json = file_get_contents('https://{AccountNumber}:{AuthToken}#api.twilio.com/2010-04-01/Accounts/{AccountNumber}/Calls/{CallSid}/Notifications.json');
Then use this line to get the returned JSON into an associative array
$obj = json_decode($json, true);
Now if all you want is the error code its stored as the following variable
echo $obj[notifications][0][error_code];
However, the full error info is also returned as a URL encoded string. You can access this by first urldecoding it, and then parsing the query string into an array with the following line
parse_str(urldecode($obj[notifications][0][message_text]), $output);
And you can now access the variables within like this
echo $output[Msg]; // Error text for failure eg invalid phone number
echo $output[phonenumber]; // Phone number for failed call
echo $output[ErrorCode]; // 5 digit error code
echo $output[LogLevel];` // Log level of error eg WARN
As far as I know this is not implemented in the PHP helper library, so you have to code for it manually

Twilio clientId is not valid when dequeing a call from a TwiML queue

I'm using Twilio's TaskRouter to redirect inbound calls to agents.
I'm using the <enqueue> verb to enqueue the inbound call and when a worker is assigned I return the following JSON to call the agent:
{
"instruction": "dequeue",
"to": "client:company-1-client",
"from": "+101388558",
"post_work_activity_sid": "<ActivitySID>",
}
I've added allow_client_incoming("company-1-client") but I get the following error:
code 21211
Called is not valid: client:company-1-client
I'm following this tutorial to get TaskRouter to call the my agent: https://www.twilio.com/docs/taskrouter/twiml-integration
What am I doing wrong?
Thanks!
So It turns out my setup was correct. The only problem was that one is not allowed to user "-" in the client name.
From Twilio Docs: https://www.twilio.com/docs/api/twiml/client
The client identifier currently may only contain alpha-numeric and
underscore characters.

StatusCallback does not work as expected

Overview:
I am working on a VB.NET application that places a call into Twilio, the number is not a test number. I am using the C# library with the code written in VB.Net.
When I use this line of code:
Console.WriteLine(account.SendSmsMessage(Caller, to1, strBody))
I receive a text message on my phone however the post back is never posted to my website. I have included the URL of the site on the account under Messaging > Request URL.
When I reply to the message, Twilio does make a post to my site. From what I understand, a POST should have been made when Twilio was first sent a message from my application, however this is not the case.
When using this code, I do not get any text message and no POST is made.
Console.WriteLine(account.SendMessage(Caller, to1, strBody, PostBackURL))
I have tried SendSMSMessage, I have tried it with the URL on my account and without it,
nothing seems to effect the behavior.
I need the SmsMessageSid at the time the message is sent. From everything I have seen, Twilio does not provide a response other then what is sent to the PostBackURL, I could parse a response for the
SmsMessageSid however since there is no response that is not an option. If I am mistaken on that point that would be great, however it looks like the only way to get a reply is with the post back URL. Thanks for your help with this! Below you will find an excerpt of the code I am working with:
PostBackURL = "http%3A%2F%2F173.111.111.110%3A8001/XMLResponse.aspx"
' Create Twilio REST account object using Twilio account ID and token
account = New Twilio.TwilioRestClient(SID, Token)
message = New Twilio.Message
Try
'WORKS
'Console.WriteLine(account.SendSmsMessage(Caller, to1, strBody))
'DOES NOT WORK
Console.WriteLine(account.SendMessage(Caller, to1, strBody, PostBackURL))
Catch e As Exception
Console.WriteLine("An error occurred: {0}", e.Message)
End Try
Console.WriteLine("Press any key to continue")
Console.ReadKey()
I'm doing something similar with C# and like you, I'm not getting the POST to the callback URL. I don't know why that's not working, but if all you need is the sid when you send the message, you should be able to do this:
message = SendSmsMessage(Caller, to1, strBody))
and message.Sid will give you what you need, assuming no exceptions.

Twilio sms not coming in mobile

I have implemented test twilio sms application. I have downloaded three files from https://github.com/benedmunds/CodeIgniter-Twilio
I have used my account_sid, auth_token in twilio.php file which is in config folder. I have also used 'from' number as +15005550006 in that file.
I have used following codes in my controller
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Twiliosms extends TL_Controller {
function __construct()
{
parent::__construct();
}
function index()
{
$this->load->library('twilio');
$from = '+15005550006';
$to = '+91xxxxxxxxxx';
$message = 'This is a test...';
$response = $this->twilio->sms($from, $to, $message);
//echo "<pre>";print_r($response);echo "</pre>";
if($response->IsError)
echo 'Error: ' . $response->ErrorMessage;
else
//echo 'Sent message to ' . $to;
echo 'Sent message';
}
}
Now when I run the controller file in the browser(not in my machine but in server), it runs successfully and it shows "Sent message".
But no sms is received. Please help.
My name is Jarod and I work at Twilio. There are multiple reasons this could be failing so lets walk through them one at a time.
1. Sending an sms using Twilio test credentials will not result in an sms being sent.
Test credentials are used for testing and debugging your application. They are "fake" numbers, that do not send any data via carrier, but instead return preset error codes and responses in order to test response-handling in your application. As you experienced this specific test credential +15005550006 will always return NO ERROR, whereas +15005550001 will always respond with "This phone number is invalid".
2. You can only send SMS from a Twilio number or a verified phone number.
You can always send an SMS from a number you bought on Twilio.com, but in order to send an SMS from any other number you must first verify that phone number with Twilio. Read more about the difference here.
These are the most common reasons for not receiving and actual SMS but in the case of the Indian phone numbers it could very well be one of these rare limitations.
If none of these work we probably need to look into your specific account to find out what's happening, in which case you should reach out to support#twilio.com.
Hope this helps.
I banged my head against the walls for three hours and tried to work out with the number Twilio gave me at the time of sign up . But It always gave me the following error
{ "code": 21212, "message": "The 'From' number +234234234 is not a
valid phone number or shortcode.", "more_info":
"https://www.twilio.com/docs/errors/21212", "status": 400 }
At the end i got the exact point from where I got my test phone number for sms / call
Get your test phone number from Here .
You will have to make the from number a number you have verified with Twilio that you own: you can't just pick any number and use it. Do you own +15005550006, and have you verified that number in the Twilio admin console?
