Google Business Messages - Missing parameter in Message

For Google Business Message webhook request, there is a metadata object which shows some details of the person and the platform who sended a message to our google business message chat, but this parameter is missing in the SDK.

Deserialization issue when retrieving event messages

The client throws an exception when attempting to retrieve a conversation message of type event. When inspecting the stack trace, this error message appears:

Error converting value "event" to type 'MessageBird.Objects.Conversations.ContentType'. Path 'items[0].type',

On initial inspection, issue seems to be the lack of an Event enum member in MessageBird.Objects.Conversations.ContentType.

Steps to reproduce

1. Start a conversation
2. Send a message of type event with some text content (e.g. when adding a note from a Flow)
3. Call ListConversationMessages from SDK client for that conversation

Excepted

• Event message is retrieved successfully and content can be read

Update `MessageBird.Objects.Common.Language` to match the web app

Hi,
I just query SMS messages:

It just started recently, so I guess I have made a request before (or someone else). It is a shared account between some projects.

But if you store an invalid originator, you also have to return it.

How to create steps for call flows?

Hi,

I had a look to the API for call flows, but I have no idea how to create a say-step:

https://developers.messagebird.com/api/voice-calling#call-flows

How can I pass additional properties to the step? I think Step and Options should derive from JObject to make this possible.

Sending verification request not working

Shouldn't orgininator be recipient?

File: csharp-rest-api/MessageBird/Objects/Verify.cs
Code: public Verify(string originator, VerifyOptionalArguments arguments = null) { ... }

Dependency & NuGet issue with Json.NET

Hi, I noticed that the list of dependencies on NuGet is not up-to-date with the configuration of the project:

But when I try to use the library there is an error as the library is looking for Json.NET 11.0, it might be interesting to add the dependency to the package definition.

Also, I had a look at the code and it doesn't look like it's mandatory to use the v11 for this project. Would it be possible to push a NuGet version with a more flexible list of dependencies ? My project can only support json.net v10.

Thanks,

VoiceMessageOptionalArguments is missing Originator

Strong name sign nuget release

This helps with verifying releases and unsigned assemblies cannot be loaded when products are released.

Support request timeouts for outgoing requests

Sending template message in whatsapp

I am beginner with this api. How can we send templated message with whatsapp with this api.
Can you please give me a sample code.

Bug in validation of field Originator

There is a bug in the validation of the field Originator.
When a value only exists of numeric characters (so being a phone number) then the value should not be validated on the length. This validation should only be applied on an alphanumeric value.

I noticed this bug because MessageBird sells Virtual Mobile Phone numbers, that can be 13 characters long (e.g: 3197001122334). The validation fails on this, and it shouldn't.

I made a proposal for a fix and added some tests. See PR #16
Please verify. Thanks.

TokenLength Parameter Not Working in 2 Factor Authentication with number

Hello Team,

We are implementing Message Bird API for implementing Two Factor Authentication in C# language. While doing that we were trying to use parameter tokenLength to set the size of token(OTP). But unfortunately its not sending code of given size instead every time it sends 6 Digit code only even though we have requested for 8 digit code.

We are using nuget package version 1.6.0

Is anyone maintaining this project?

I'd be happy to help

Support for Numbers

https://developers.messagebird.com/api/numbers/#fetching-all-purchased-phone-numbers

it's missing from the SDK right?

Google Business Messages - Missing parameter in Contact

For Google Business Message webhook request, there is a displayName property which shows the display name of the person who sended a message to our google business message chat, but this parameter is missing in the SDK.

Originator not coming through on Voice or SMS

In testing MessageBird, it doesn't matter what Originator I use in a voice message, it is always delivered with a blocked number (in the US).

How can I get my number to be used when sending voice messages?

Support for SMS Status Reports Missing

The status reports are also not implemented, would be good to get this added too.

https://developers.messagebird.com/docs/sms-messaging#handle-a-status-report

NuGet Package may not be fully compatible with NETCORE2.0

I got this warning when using the nuget package in a .net core v2.0 project

Package 'MessageBird 1.3.4' was restored using '.NETFramework,Version=v4.6.1' instead of the project target framework '.NETCoreApp,Version=v2.0'. This package may not be fully compatible with your project.

Eventually this will be a dealbreaker for us.

Problem with JSON serialization when using a global enum converter

Hello,

In our project we changed the default JSON.NET configuration to use a enum to string converter globally. Meaning all enums are converted to strings when serialized.

This however causes the messagebird library to stop working, this is due to the Class field in the Message.cs file being an enum, which then is serialized to a string while the underlying messagebird API expects a int.

We currently worked around it by making a fork and changing the Class field to an int, see: Fenetre@2b151fe

But I imagine you would not want to fix it like this and instead use isolated JSON.NET serialization settings instead of the global once.

No callstatus for no_answer

I am trying to get a list of all calls. I am using the client.ListCalls(); function.

However there's no CallStatus for the status 'no_answer' making the function crashes.

How Do I Fetch All The Conversations That Belong To A Contact?

Currently The code i have fetches everything then filters on all results, the payload can be heavy in the future for this.

[HttpGet("{contactId}")]
public List GetConversations(string contactId, [FromHeader(Name = "keys")] string headerKeys)
{
JavaScriptSerializer serializer = new JavaScriptSerializer();
MessageBirdKeys mbKeys = serializer.Deserialize(headerKeys);

        var restClient = new RestClient(CONVERSATIONS_ENDPOINT, mbKeys.AccessKey, null);
        var client = Client.Create(restClient);

        ConversationList conversations = client.ListConversations();
        return conversations.Items.Where(i => i.ContactId == contactId).ToList();
    }

Any support for async/await

At the moment all API requests in C# clients are executed synchronously. Is there plan to introduce asynchronous methods with async/await and cancellation token support?..

WhatsApp image caption is missing

When an image comes from whatsapp , message.content.image property includes caption property, but in sdk, MediaContent class only includes url property. Am i using the wrong class, or is caption property missing ?

Thanks.

Google Business Messages - Rich Text issue

https://developers.google.com/business-communications/business-messages/guides/how-to/message/send#rich_text

If the documentation above is the right documentation for Google Business Messages that can be installed and used via MessageBird, those rich text, how can i set 'containsRichText': 'true', to be able to use rich text features in GBM ?

Sending File in WhatsApp Sandbox

I am sending a pdf file in whatsapp sandbox, but file is not received. And i got no error or exception while sending.

Is it a bug? Or whatsapp sandbox does not allow sending files?

Google Business Messages - Supported media types

In the documentation here https://developers.messagebird.com/api/conversations/#supported-media-types-per-platform

Documentation shows that Google Business Messages support only image media type.

Is there another media types that can be supported ? Is this related to a restriction in Google Business Messages? Or the other possible media types haven't been supported or implemented by MessageBird ?

Async API

It would be nice to have async versions of the client methods using HttpClient instead of HttpWebRequest. I don't think I'll have time to try and submit a pull request unfortunately.

I can't find a function to update a ConversationWebhook

There are the functions to:

• Create: CreateConversationWebhook(...)
• List: ListConversationWebhooks(...)
• View: ViewConversationWebhook(...)
• Delete: DeleteConversationWebhook(...)

But there is no function to update.

publish this library to NuGet

I would be nice to have this library available in NuGet.

Allow value "auto" for DataEncoding

The enum used in the library consists only of two values:
public enum DataEncoding { [EnumMember(Value = "plain")] Plain, [EnumMember(Value = "unicode")] Unicode };

But in the API documentation at https://developers.messagebird.com/docs/messaging a 3rd value is descibed:

The datacoding used, can be plain (GSM 03.38 characters only), unicode (contains non-GSM 03.38 characters) or auto, we will then set unicode or plain depending on the body content.

Can you add the value auto the this enum does a reason exist to not use "auto" from .net / C# side?

ContentType is missing 'whatsAppSticker' and throws

Conversation messages with status == 'rejected' cause error during ListConversationMessages call

During a call with the client to:

messageBirdClient.ListConversationMessages(conversationId);

got error

Error converting value "rejected" to type 'MessageBird.Objects.Conversations.ConversationMessageStatus'. Path 'items[1].status', line 1, position 1187.

Because response contains a message with status = 'rejected', as 'rejected' is missing in public enum ConversationMessageStatus.

Please fix asap!

Support for 'Verify' is missing

Please add support for Verify functionality:
https://developers.messagebird.com/docs/verify

Add support for email verify

WhatsApp sandbox - Can Not Send WhatsApp Sandbox message after updating nuget to version 3

#87
I updated MessageBird nuget package to version 3.0.0

accesskey, channelid and conversationid parameters are from WhatsApp Sandbox page.

When i want to send message, i get error NotFound description: 'Conversation not found' parameter: ''

What can be wrong here ?

                Client _client= Client.CreateDefault("accesskey");
                ConversationMessageSendRequest _request = new ConversationMessageSendRequest()
                {
                    ChannelId = "channelid",
                    Type = ContentType.Text,
                    ConversationId = "conversationid",
                    Content = new Content() { Text = "hello" }
                };
                ConversationMessage message = _client.SendConversationMessage(_request.ConversationId, _request);

Support for Verify HttpRequests Missing

As per: https://developers.messagebird.com/docs/verify-http-requests

I'm want to add filters to the ListMessages method. To my suprise only the status filter option is available. Now I still need to build my own httpclient implementation...

Webhook request verification error

I am using WhatsApp sandbox.

I implemented request verification from sample code

var requestSigner = new RequestSigner(GetBytes("SIGNING_KEY"));
// @param expectedSignature Signature from the MessageBird-Signature header in its original base64 encoded state.
const string expectedSignature = "EXPECTED_SIGNATURE";
var request = new Request("1544544948", requestParams, GetBytes(requestBody));
requestSigner.IsMatch(expectedSignature, request)

Request verification is working for incoming messages, i have no problem with that. But after i send the response, messagebird api sends a new webhook for delivery status, but request verification is not successfull for that second request.

I am using the same verification code. What can be the issue here ?

Originator regex too restrictive - forbids use of spaces

Spaces are valid characters in the Originator string, see this MessageBird support page.
However, the regular expression in the Message.Originator setter method only allows the string to contain characters of the alphabet and digits.

	Regex
Current version	^[A-Za-z0-9]+$
Suggested	^[A-Za-z0-9\s]+$

reportUrl is missing from messages

The reportUrl field is missing from SMS, MMS and Voice messages.

See:
https://developers.messagebird.com/docs/sms-messaging#handle-a-status-report

Resources not always disposed

In the RestClient.cs there is the following code:

csharp-rest-api/MessageBird/Net/RestClient.cs

Lines 203 to 206 in c6e2199

	using (var requestWriter = new StreamWriter(request.GetRequestStream()))
	{
	requestWriter.Write(body);
	}

Looking at the source for StreamWriter in .NET Core latest (should be similar in other runtimes) this only closes but does not dispose the inner stream.

It might be prudent to change the start of the code to:

using (var stream = request.GetRequestStream())
using (var requestWriter = new StreamWriter(stream))
{
    requestWriter.Write(body);
}

The specific reason I'm asking for this, is that we're seeing ErrorExceptions with inner SocketExceptions claiming AddressAlreadyInUse (10048) errors. This happens after we send a few thousand SMSs, and seems to indicate that sockets on the host are being consumed faster than they become available. So maybe if we don't wait for the GC to collect the .GetRequestStream(), and instead dispose via a using as I suggest, things might improve.
