I push a lot (10Ks) of messages to Slack channel webhooks each month. It's not uncommon for the Slack API to return network errors, like ECONNRESET, meaning I don't know if the message was sent or not.
You can resend (POST) to the Slack chat.postMessage endpoint, but that might deliver the message twice.
Is there a way to idempotently send a Slack message once to a channel using Slack webhooks?
Slack Webhooks provide a very limited set of functionality.
Idempotency is not one of them.

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.
I am developing MS teams bot.
I am creating a function to send a webhook automatically when I receive a message.
The development was carried out by referring to the URL below.
https://learn.microsoft.com/en-us/microsoftteams/platform/webhooks-and-connectors/how-to/add-outgoing-webhook
Like the URL above, teams support outgoing webbook.
However, the outgoing webbook must manually enter #mention in the chat window for the bot to work.
I want to tag #mention automatically when I receive a message
Is there a way to do a webhook?
Even if it's not an outgoing webbook,
The robot or ms flow can receive messages and send messages automatically.
I want to develop a robot.
You also need to provide that bot for use by multiple teams.
I'm not sure if you can automatically sync all messages in a channel. But you can use the graph API to constantly check the channel for new messages and pull them into your service.Graph API
You can subscribe to notifications for Microsoft Teams messages. This feature is available in beta on the Microsoft Graph API.
I'm building a Slack (instant messaging) chat client, I'm looking for a way to trigger a notification to receipent when a new message is sent to him, push notification of course.
What's the endpoint or stream API to be able to trigger a push notification to devices?
I think it should be some backend microservice listening for incoming messages in a channel with a list for users to notify.
If you want to get instant notifications about new messages posted to a channel you can either use the Real Time Messaging API (RTM API) or the Events API.
The main difference:
RTM API uses Websockets and you will receive a constant stream of events about everything that happens on the connected workspace.
Events API uses standard HTTP requests and Slack will only send events to your endpoint that you subscribed too.
There are many factors to consider when choosing the right API for a project. Please also see the official FAQ from Slack on the topic for more details.
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.
I wrote some bot that sends messages to some channel using nodejs. This bot is an admin in that channel and it can see messages from users using /getupdates api. However it can't see own messages. Is there any way to do that?
