I'm trying to figure out twilio. I need to use a predefined phone number, so I bought one. But I do not see any way of actually getting sms's from it as REST. It seems like twilio follows more complicated schemas when getting texts from phone numbers. Like there is an option for WebHook, TwiML Bin, etc. Is there just a REST url I can access to get all the sms's from this number?
I was able to do this:
var messages = MessageResource.Read(limit: 20);
But this seems to allow me to read messages from all my sms's, even those that are not coming from a fixed phone number.
Background: my app will be a windows app, so I need a simplest way to read sms's possible. No web hooks and I do not need to send sms.
OK, I've figured this out. It was very easy:
var messages = MessageResource.Read(limit: 20, to: new Twilio.Types.PhoneNumber("+12345678901"));
Where +12345678901 is your registered phone number in Twilio system in + format.

I am working on an appointment confirmation system where I need to bind the SMS response 'Y' or 'N' to some meta data and send that meta data to my API via the Twilio webhook.
I am using.NET SDK from Twilio and trying to add attributes to the SMS message (MessageResource) which their documentation states:
Attributes:
STRING PII MTL: 30 DAYS
"The JSON string that stores application-specific data. If attributes have not been set, {} is returned."
link to docs: https://www.twilio.com/docs/chat/rest/message-resource#message-properties
which is more like metadata which is what I need but when I try finding any 'attributes' property in my C# code with their SDK I can't find it.
Here's my code:
var twilioMessage = MessageResource.Create(
body: msg,
from: _configuration["Twilio:FromPhoneNo"],
to: new PhoneNumber(phoneNumber),
attempt:1,
attributes: "{"id":"test"}" //this property doesn't work
);
var attributes = twilioMessage.attributes; //this doesn't work either
Any help will be highly appreciated.

I'm afraid you are looking at the wrong documentation for sending SMS messages there. This documentation is for sending a chat (app to app) message. The documentation for sending an SMS is here.
Sadly, SMS messages do not have the ability to bind custom attributes to them. It is simply something that doesn't exist in the protocol.
You are sending an appointment confirmation and expecting a "Y" or "N" response. I am guessing you are trying to add the ID of the appointment in the case that you send confirmations for more than one appointment to the same phone number and you need to work out which appointment the response is about. There's a further issue here in that, as an end user, you cannot reply to a specific SMS messages. SMS is purely chronological.
There are 3 ways I can think of to work around this:
Only send one confirmation at a time. If you are still waiting for a response to a confirmation, don't send another one until you get that response. This might not work if users don't respond to confirmations.
Have the user include the ID of the appointment in the response. This is flaky because it relies on the users getting things right and you want to make things as simple as you can for them
When you need to send more than one confirmation at a time, use different Twilio numbers to send the confirmations. Then you can tie the confirmation response to the appointment by inspecting the Twilio number that the user sent the message to.
Number 3 is the most sound way of doing this. It shouldn't require you to have too many extra numbers, just as many as you might have concurrent appointment confirmations.
Let me know if this helps at all.
I am trying make phonecall via Twilio using c# i am using the below code to make call.code executes successfully but i wont receive call.In my twilio page it shows staus as completed and durations.
const string accountSid = "ACe200aeb6115e1f3038a012e1103bd874";
const string authToken = "6XXXXXX";
TwilioClient.Init(accountSid, authToken);
var to = new PhoneNumber("+12025688652");
var from = new PhoneNumber("+919500553163");
var call = CallResource.Create(to,
from,
url: new Uri("https://demo.twilio.com/welcome/voice/"));
Console.WriteLine(call.Sid);

I believe that you are actually making that call successfully. You are not experiencing the call yourself because of the parameters you have used.
You are making the call from your verified number. This is your real phone number, but when you set it to be the from address that just means Twilio will use it as the caller ID for the call.
For the to address you are using your Twilio number that you have bought within your account. When you make calls to that number, Twilio makes a webhook (HTTP) request to the URL that is set as the voice response in the number's settings. Currently, that is still set to the default, so Twilio retrieves this URL: https://demo.twilio.com/welcome/voice/. If you click through, you will see that this just reads out a message.
The URL you use when you create the call is also the default URL.
So what is happening with the call is that Twilio is using your caller ID to dial your Twilio number and when the call is answered, both sides of the call are reading out that message to each other.
If you want to at least make your own phone ring, then I'd start by reversing the to and from numbers in your API call. If you do that, then you should receive a call on your phone and when you answer it you will hear the demo message. Then, once you've done that you can start writing your own TwiML responses, possibly using Twimlbins to get started or by building your own application.
Let me know if this helps.
The docs say that the from can be a phone number OR client
https://www.twilio.com/docs/api/voice/making-calls
From: The phone number or client identifier to use as the caller id. If
using a phone number, it must be a Twilio number or a Verified
outgoing caller id for your account.
however - the c# sdk doesnt seem to support the from being a Client - anyway to use a client instead of a phone number? using twilio voice SDK for ios and trying to allow the call receiver to see it as a "missed call" so they can call back.

The helper library asks for an IEndpoint as the to parameter. There are a two classes that implement IEndpoint: PhoneNumber, Client.
var to = new Client("Bob");
var from = new PhoneNumber("+15017250604");
var call = CallResource.Create(to,
from,
url: new Uri("http://demo.twilio.com/docs/voice.xml"));
Hope that helps.
I am new to using Sendgrid emails using c# .Net library. Our requirements wants us to track the status of the email like Delivered/Went to Spam/Client opened/reported as spam etc., By looking at the documentations and answers from other users to my previous questions its my understanding that there is no direct way to track the status of the email (like result object).
It would be really helpful if someone can point me to some example/sample codes or documentation/implementation in C# for the following
1) Adding unique parameters while sending the email using send grid API. Can I use a Guid string as my argument
I am assuming what I am doing below is correct.
var myMessage = new SendGridMessage();
var identifiers = new Dictionary<String, String>();
identifiers["Email_ID"] = "Email_ID";
identifiers["Email_Key"] = "9ebccd0d-67c0-4c28-bbf3-83d5bb69f098";
myMessage.AddUniqueArgs(identifiers);
2) How to use event webhooks to get the status with the unique argument that I used above from the http_post so that I can associate an email to the status. Any sample code , documentation in c# or an overall idea of how this works will get me started on this.
Appreciate your time and answers.
Sending emails via SendGrid is easier from C# using the official library that SendGrid provides. From your code example, it looks like you may already be using this - good job.
The unique argument should work as long as its been stringified, and you're not trying to pass an object to myMessage.AddUniqueArgs.
The Event Webhook will send a JSON packet to any URL that you specify. If you have included unique arguments in an email that you send out via SendGrid then these are automatically added to each event response you get back from the webhook - you don't need to turn anything else on to get the arguments as well.
There is an example of this call and the resulting response in the SendGrid Documentation.
SendGrid has an Event Webhook which posts events related to your email
activity to a URL of your choice. This is an easily deployable
solution that allows for customers to easiy get up and running
processing (parse and save) their event webhooks.
This is docker-based solution which can be deployed on cloud services
like Heroku out of the box.

This question relates to Twilio and the API for it (C#).
I do not have a website nor a web application, just a need to send SMS notifications to my own private mobile when something happens on a server (NOT a webserver). I have already, successfully, sent SMS to my mobile from a C# dll. I want to check the status of the message. All the references imply website/web application use cases, and getting the status using a URL.
How do I do this in C#? Is there an example of the suggestion made here? No PHP or other web servery technology.
The solution I found, was ridiculously simple. The suggestion (made here) was to hang on to the message id. I discovered the GetSMSMessage method on TwilioRestClient. So querying message status some time after sending will give you the updated status.
By the way, the one thing you'll want to watch out for is that if you query the API too soon, you might get a status of "queued" or "sending" rather than "sent" or "failed", so be sure that your logic is set up to handle these other possible responses.
Also good to keep in mind that if you try to send more than 1 message per-second via a Twilio phone number, Twilio will queue the excess messages and release them at a rate of 1 message per-second per-number. This comes into play because if you have a burst where you send 10 messages in 1 second, but then you go to retrieve the status of the messages after 5 seconds half of the messages will be "sent" and half will be "queued".
If you dont have a callback url. Just call the method
TwilioClient.Init(accountSid, authToken);
var message = MessageResource.Create(
body: "Join Earth's mightiest heroes. Like Kevin Bacon.",
from: new Twilio.Types.PhoneNumber(fromNumber),
to: new Twilio.Types.PhoneNumber(toNumber)
);
Console.WriteLine(message.Sid);
//Get the status from twilio
TwilioClient.Init(accountSid, authToken);
var verificationCheck = MessageResource.Fetch(message.Sid);
Console.WriteLine(verificationCheck.Status);
where Sid is the id you get back from Twilio.
