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.

I am trying to send a whatsapp message via Twilio Business Account, from a number my company has registered via twilio and configured to be a sender.
In the Twilio logs, I see error 63016 message not in template, even though I double-checked every word and spacing to see that my message matches the approved template
some code to help:
def send_message(phone, template_message):
try:
message = twilio_client.messages.create(
body=template_message,
from_=f'whatsapp:{MY_SENDER_NUMBER}',
to=f'whatsapp:{phone}'
)
except TwilioRestException as e:
return False, e.msg
return True, ''
this completes with no error and results in this log line in twilio
From,To,Body,Status,SentDate,ApiVersion,NumSegments,ErrorCode,AccountSid,Sid,Direction,Price,PriceUnit
"whatsapp:+XXXXXXXXXXXX","whatsapp:+XXXXXXXXXXXX","MY MESSAGE THAT MATCHES THE TEMPLATE,
WITH SOME NEWLINES!
AND some characters like '' and ,
",UNDELIVERED,2021-04-11T07:58:32Z,"2010-04-01",1,63016,XXXXXXXXXXXXXXXXXXXXXXXXXXXXx,XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXx,"
outbound-api",0.0,USD
note: if I open my whatsapp and sends the sender a message, then if I run this code again it will work and I will see that message (as that message does not have to match a template for a 24-hr window).
After help from Twilio support, it was a missing '\n' in the message that I was trying to send, that caused the message not to match the template.
I had the same problem, but was due to just a simple whitespace.
I need to have the exact request URL that Twilio makes when sending an SMS. Is there a way to print/log it? When I use the Message.getUri method, it gives me something that ends with .json which I think is the response from Twilio after making the request. From what I've read, it should look something like "https://api.twilio.com/2010-04-01/Accounts/<Account_SID>/Messages".
I'm using the Java API:
com.twilio.rest.api.v2010.account.Message
.creator(new PhoneNumber(toNumber), // to
new PhoneNumber(twilioFromNumber), // from
textMessage)
.create();
The URL is indeed
https://api.twilio.com/2010-04-01/Accounts/ACXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX/Messages.json
where ACXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX is the account SID which you can find on your dashboard if you login in your Twilio account console at https://www.twilio.com/console
See more docs at (https://www.twilio.com/docs/sms/send-messages?code-sample=code-send-an-sms-message&code-language=curl&code-sdk-version=json#linkcode)
I'm using postman to see the response format of send message api in Twilio. The Api that I'm using is https://api.twilio.com/2010-04-01/Accounts/{AccountSid}/Messages.
I have entered the basic authentication parameters (Account_Sid and AuthToken as username and password) the json request format is
{
"To":"My Number",
"From":"Twilio Number",
"Body":"Hello this msg is from postman"}
But I'm getting error 21603 which states "A 'From 'phone number is required". Can you please tell me where I'm wrong. The messages are sent when using Twilio console.
I can't see your Postman but, maybe this is what you're missing...
Click on the Body tab and make sure form-data is selected from the radio buttons.
Also if you go to Twilio docs page (https://www.twilio.com/docs/sms/send-messages) you can see the expected response if you click on the OUTPUT link (tab) that is located at the top right of the code sample.
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?

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
I am currently integrating into the twilio rest api and need to perform a check on a users phone number to determine if that user has blacklisted themselves or not. I have little experience with this api and scouring through the documentation and google has turned up nothing.
In our application we are going to have a notification center and if the user has blacklisted themselves I do not want to give them the ability to turn on their SMS notifications. Potentially a user could have SMS notifications on but twilio would block any messages. I know there is the ability to get a status code back from twilio when an SMS is queued that shows the user is blacklisted (https://www.twilio.com/docs/api/rest/message). However, I will not be sending messages on the notifications screen and need a direct way (if at all possible) to check twilio to determine if a number is blacklisted. Any help is much appreciated. Let me know if anymore information will be of help.
Megan from Twilio.
I'd be curious to see if you ever tried your own workaround. But I wanted to note for others in a similar situation how you could grab the blacklist error and then do whatever you may want with it.
In Ruby it would look something like this:
require 'rubygems'
require 'twilio-ruby'
account_sid = 'YOUR_ACCOUNT_SID'
auth_token = 'YOUR_AUTH_TOKEN'
#client = Twilio::REST::Client.new account_sid, auth_token
begin
#message = #client.messages.create(
from: 'TWILIO_NUMBER',
to: 'USER_NUMBER',
body: 'Howdy!'
)
rescue Twilio::REST::RestError => e
if e.code == 21610
# User is blacklisted
# Store info however you choose
puts e.message
end
end
We check for blacklisting specifically using the code '21610'. For more information about errors you can visit the reference page.
Hope this helps!
Twilio recommends developers to store the opt-out/in statuses in their side. I have stored it in DB. There are 2 ways to collect the unsubscribed users list.
1) Use SMS webhooks. You can find how to configure your Twilio number to receive webhook events here
#PostMapping(value = "/twilio", consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE,
produces = MediaType.APPLICATION_ATOM_XML_VALUE)
public String twilioConsumer(TwilioEventDTO twilioEventDTO) {
// twilioEventDTO.getBody() => returns the body of the SMS user replied.
twilioService.consume(twilioEventDTO);
return new MessagingResponse.Builder().build().toXml();
}
2) Since I implemented webhooks later, I had to collect already unsubscribed users. When you send sms to the number that has been opted-out, Twilio API throws an exception with the status number of 21610. You can catch it and store the number in DB.
try {
Message result = Message.creator(
new PhoneNumber(toPhoneNumber),
new PhoneNumber(fromPhoneNumber),
messageBody)
.create();
response = result.getStatus().name();
} catch (ApiException e) {
if (e.getCode().equals(21610))
updateSubscription(toPhoneNumber, false);
logger.warn("Error on sending SMS: {}", e.getMessage());
}
