Slack incoming webhook vs postMessage Web API - webhooks

What is the difference between incoming webhook and slack chat.postMessage webAPI?
When should we use one over another? I have a slack app, I want to send messages to particular channel as a User. I found an option to post message as a User in chat.postMessage, can I achieve this by incoming webhook?

To your specific question. Its technically possible to send messages on behalf of a user with chat.postMessage by using a token from that user and setting as_user to true.
For example if you installed a Slack app the created app token will be linked to the installing user and you can use it send messages on behalf of the installing user.

Can MS bot service message end point detect user's edit behavior?

Context
Currently we are using Azure Bot Service. The Bot Service is setting up an message endpoint which is directed to our on-pre server
We can successful detect an request coming in when user send something through bot.
But when user edit the previous messages, not request comes in
Message endpoint on Azure
User send a new message on bot
User edit a message on bot
Question
Does there exists a way to receive the update request when users edit their previous messages on bot?
Check out the link mentioned below to verify "Update Activity" section which is nearer to the current requirement.

is it possible to send broadcast messages using Twilio whatsapp API

I am trying to integrate Twilio WhatsApp API with my application, is it possible to send broadcast messages using Twilio.
Twilio developer evangelist here.
You can send outbound messages over WhatsApp using Twilio. There are some constraints though.
You need to get your users to explicitly opt in to receive WhatsApp messages
When you send a notification to a user, if it is more than 24 hours since the user sent you a message you can only send approved template messages.
Twilio Notify does not support WhatsApp, so to broadcast messages to a group of users you will need to make one API request per message using the regular Twilio messaging API.
Let me know if that helps at all.

Node and Microsoft Teams API

I'm building a Node only application that reads logs in the background and based on an event being read will send a message to a Teams channel directly.
I've been having quite a few issues getting a Graph API access token valid through Username and password.
I have been able to get a Graph API access token with client secret and tenant id which represents access
"without a user". Now that does not allow me to post a message in a channel as I would need to have access "on behalf of a user".
API => https://graph.microsoft.com/v1.0/teams/{team-id}/channels/{channel-id}/messages .
Would there be another way of achieving this? Webhook/Connectors?
Thank you!
There's a few different ways you can post to a teams channel, you can set up like you said an http webhook, where you could call it to post into a channel https://learn.microsoft.com/en-us/microsoftteams/platform/webhooks-and-connectors/how-to/connectors-using
You can use power automate (flow) or logic apps to post messages as the flowbot, or you can write a bot/ use the bot framework to register a bot that can post to teams, called proactive messaging: https://learn.microsoft.com/en-us/microsoftteams/platform/resources/bot-v3/bot-conversations/bots-conv-proactive
As for trying to use graph with application permissions, that's not possible, at least for the moment.

Is there a way to push notification via a chatbot deployed in facebook developed with dialogflow w/ node.js for fulfillment

I'm developing a facebook/workplace chatbot using dialogflow with node.js for fulfillment. Can't seem to find resources for pushing notifications.
I want to be able to trigger sending the message by visiting the webhook url.
You need to use the Facebook Graph APIs to send a facebook notification to a specific user. User can click on the notification to launch the facebook messenger chatbot.
Here is a quick example.
https://graph.facebook.com/v3.0/{user_id}/notifications?template={your_message}&href={link}&access_token={page_access_token}
You can read more about it here: https://developers.facebook.com/docs/graph-api/reference/user/notifications/
Basically, you need to run a web service which when called makes the calls to the facebook notification APIs.
All you need to do is pass the user id, the message/link to be displayed in the notification and the page access token.
When someone first sends you a message via Facebook, Facebook provides you the page-specific user id which you can store in the database.
Page access token can be accessed by going to https://developers.facebook.com/apps

How to get conversation details in microsoft bot framework for skype?

I'm able to get conversation details for webchat using https://webchat.botframework.com/api/conversations/[conversationId]/messages
Service URL for skype channel is https://skype.botframework.com, but I dont find any documentation for getting conversation details
You can use the DirectLine Rest API (see docs).
The Direct Line API is a simple REST API for connecting directly to a single bot. This API is intended for developers writing their own client applications, web chat controls, mobile apps, or service-to-service applications that will talk to their bot.
Within the Direct Line API, you will find:
An authentication mechanism using standard secret/token patterns
The ability to send messages from your client to your bot via an HTTP POST message
The ability to receive messages by polling HTTP GET
A stable schema, even if your bot changes its protocol version
You need to enable the DirectLine channel for your bot on (see screenshot)
You don't have to access each specific channel endpoint separately, you can do it all (with some limitations) through the DirectLine API.
Start a New Conversation
POST /api/conversations
Get Messages in a Conversation
GET /api/conversations/{conversationId}/messages
Send a Message
POST /api/conversations/{conversationId}/messages
The full details are in the docs as linked above.
Hope this helps
Can you be more specific about conversation details and what you're looking for?
Generally, you shouldn't assume those URL's are static BTW; an incoming message from the Bot Framework will have a ServiceURL that should be used for the life of that conversation. Some services may have multiple ServiceUrl's that they give out for different users.
