I develop a mobile app Speaking Email that reads emails out to the user, which can be used while driving to work for example. I would like to add Slack as an account type. Ideally we would have Speaking Email read out the user’s slack messages that are unread, as these will be what they need to catch up on. However it does not appear the Slack API has a method for retrieving the messages the user hasn’t read. Is this possible with the latest Slack API?
I was searching for the same thing and found their API doc about Read Messages!

Trying to send out chat message from Bot with sender as a current logged in user. I am able to implement this with graph api using On Behalf of flow. However the API is still in Beta and don't think we can use it in production setting.
https://learn.microsoft.com/en-us/graph/api/chat-post-message?view=graph-rest-beta&tabs=http
Is there a different way? Can we use ConnectorClient? Tried this, but the chat message is sent by the bot instead of the current logged in user. I am not able to create user token with botframework.com. It is always bot or the registered app.
Do anyone know if there is a way to accomplish this avoiding the graph beta api?
I am using the Twilio API for WhatsApp in a sandbox, for prototyping and testing. According to the Facebook / WhatsApp documentation, there are several types of inbound notifications that may be delivered to your unique Webhook.
Twilio API documentation is very limited and doesn’t mention any of the more advanced scenarios. For example retrieving the customers name, which should be present in every webhook request…
When I inspect the webhook, the body payload is very limited. Is there any way to receive the original channelData?
Apparently, this feature is not implemented yet. I received the following statement from Twilio.
Unfortunately we don't support the Contact name being included in the inbound Whatsapp message posted to your webhook at this time. I've raised a feature request for this with the Product Team in hopes that we'll have this feature available in the near future.
You can get the sender's name using the 'ProfileName' key from the request form.
I have created a slack bot and I want to send a general static help message to users when they send a direct message to my bot:
Should I subscribe to Events API? Or do I need to do this in another way? I couldn't find a clear answer for this.
There are two ways to do make your bot user reply to direct messages:
Events API
Real Time Messaging API
In my opinion the Events API approach is easier to implement since it does not require using WebSockets.
The basic approach with the Events API is:
You need an endpoint that can receive event requests from Slack and
react to it, e.g. by sending a direct message back to a user.
Subscribe to message.im event for your bot user
Note that a bot user already has all the required scopes for this with the bot scope.
In addition I would recommend to subscribe to app.mention for your bot user. Then it can also react to mentions in other channels.
Btw. that message you posted looks a lot like a review comment from the Slack team for a new app submission. I got a similar one for my last app and I solved it with the approach above. In general it looks like if you want to have a bot user in your app it needs to be able to respond to help request from users.
Hi I have been working on one of my apps for integrating chat using Twilio SDK. I would want to know if it is possible to get the system message inside a channel for eg: 'Member A joined the channel', 'Member B left the channel', 'Member C accepted the invitation to join' and so on. It seems like Twilio SDK does not have API to get the system messages or to set them. How can we achieve this?
I also noticed that it can be achieved by setting the custom key-value pair in attributes inside the message and sending it to the channel. But for the newly invited members, they cannot send a message when they are declining the invitation request such as 'Member A declined the invitation to join channel', as they have not joined the channel yet.

If you want to send persistent system level messages like this, you can do so with a combination of webhooks and the REST API.
The idea is that you can send messages to a channel using the REST API whenever you need one of these system messages. The default user for the REST API is the system and you can then treat messages from system as special for display in your UI.
I mention the webhooks because you can register to receive them for a number of useful events, like members joining and leaving channels. The webhooks may not cover all the things you want, like declining an invite, but for that I would just trigger my own HTTP request from the application to your server.
Let me know if that helps at all.
I created a websocket-based Slack bot (that plays chess). In order to return a graphical representation of the board (so PNG instead of simple ASCII) I must use a webhook since normal messages cannot have attachments.
The interaction with the bot is through direct messages and I have 1 webhook. If I set the channel in the wehook to '#username' the message gets posted in that user 'slackbot' DM. But I want it to be posted in my bot's DM with that user.
How do I do that?
Or is there an alternative instead of a webhook?
Thanks.

Direct messages between bot and user
If you want to use a bot-specific direct message channel instead of the general slackbot channel you need to open a direct message channel just as you would between any two users.
Open the direct message channel from your bot to a user with im.open (which will provide you with the channel ID). Then send the message to that channel ID, e.g. with chat.postMessage.
Important: Make sure you use the bot access token and not the general access token for all API calls.
Method for sending messages
I would recommend using the API method chat.postMessage instead of the webhook. It gives you more options than a webhook and of course also supports attachments.
