I have integrated Slack with our Icinga (Nagios based) monitoring and we are sending notifications from icinga to slack channels
In icinga notification's service description field we are including a URL for the monitoring page for that particular notification as HTML code but the problem is Slack is not respecting the html code and is displaying the URL as a text.
Any idea how can I make the links URL (Clickable)
We are transitioning from hip-chat to slack and I have different possibilities of escaping char, putting in direct URL but none worked
Below is the notification with direct URL in service description
SS ABC Integration - application-test- app/'http://monitoringhost.com/icinga/cgi-bin/extinfo.cgi?type=2&host=hostserver&service=Load Average per CPU' Load Average per CPU on hostserver is OK
Below is with html code in the services description
hostnameB/<a href='http://monitoringhost.com/icinga/cgi-bin/extinfo.cgi?type=2&host=hostnameB&service=SS Test Application-Demo-Sub - Last Submission Status'>SS Test Application-Demo-Sub - Last Submission Status on hostnameB</a> is OK
We want the URL to be clickable
To make a piece of text function as a link, you can send it to the API as
<http://www.foo.com|Link to foo>[1].
The system will also automatically detect URLs that are simply inserted, so if you sent -
Hey, have you seen http://www.foo.com ?, it would automatically make the URL a link.
Hope that helps!

Figure out that the script is sending all of the available variables to the slack and slack is app is picking just a few of them....
We ended up writing our own notification script; which only sends a few variables as an attachment to slack

I've created an incoming Teams Webhook connector within a Teams group (using the method below).
I can successfully curl to the webhook internally and get the message to display ok.
MS have checked my tenant and access is as expected.
When I apply my URL for the webhook to any external service they eventually come back stating there was a problem detected with the webhook (Please make sure that your webhook endpoint of xxx is responding with a 2xx response code within 30 seconds of initial connection.)
Can anyone advise what else may need to be done?
Thanks
In Microsoft Teams, choose More options (⋯) next to the channel name and then choose Connectors.
Scroll through the list of Connectors to Incoming Webhook, and choose Add.
Enter a name for the webhook, upload an image to associate with data from the webhook, and choose Create.
Copy the webhook to the clipboard and save it. You'll need the webhook URL for sending information to Microsoft Teams.
Choose Done.
Incoming webhooks are special type of Connector in Teams that provide a simple way for an external app to share content in team channels and are often used as tracking and notification tools. Teams provides a unique URL to which you send a JSON payload with the message that you want to POST, typically in a card format. Cards are user-interface (UI) containers that contain content and actions related to a single topic and are a way to present message data in a consistent way. Please test the incoming webhook url using postman and let us know the payload result or status code. Would be help full for us to understand more.
I want to utilise Google Meet api, which is used in Hangouts integration for Slack, description follows
TL;DR:
Links such as https://meet.google.com/new?gid=123&gd=qwe987 can be generated, so a modal is shown which can ask user's confirmation and then some request is sent from user's browser (where the Google Meet page is opened) to some endpoint (probably it is determined from gid which seems to be google application id). Is there a way to configure my application to have a webhook, so I can generate these custom links?
There's Google+ Hangouts app for Slack. Here's how it works (after you add the app in your workspace):
you send /hangout command in any Slack channel
slackbot sends an "Only visible to you" message in this channel with a link to start a new hangout. it looks smth like this (I changed data in the link): https://meet.google.com/new?gid=691521906844&gd=THTJ30X6W%7CU01113BD13M%7CD01113BDB5Z%7Csuren%7C%7C1846381238693%7C1%7CB01QFGG5GJF%7CE1MDm4DWcuVa0RbN5ZT9o5KF
when you visit the link, a new meeting is started instantly, and the page shows modal with text "To bring others into this video call, post a link it to your Slack channel" with buttons 'Cancel' and 'Post'.
when you click 'Post', a new message is sent to the Slack channel, where the command was sent. Text is "#Suren Khorenyan has started a Google+ Hangout and would like you to join. Join Hangout." and contains a link to the meet, which was created previously
How can I utilise this integration for another app, like Mattermost (or anything else like Telegram chats via bots)?
As I see, data in the url slightly changes. Probably it's payload for Google Meet to trigger Slack to send a message with link to the channel.
gid seems to be something like google app id
gd seems to be something like google data. If I url-decode it, it becomes THTJ30X6W|U01113BD13M|D01113BDB5Z|suren||1846381238693|1|B01QFGG5GJF|E1MDm4DWcuVa0RbN5ZT9o5KF. This is some kind of payload, separated by pipes (obviously), but I don't know what any part of this means (suren is my username in the Slack workspace, probably this is used for creating an invitation message).
When I click Post, this happens:
a new POST request to https://hooks.slack.com/services/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 is sent with form-data
hangout_id: 1812381238693
hangout_url: https://meet.google.com//abc-iuqx-def
a new message is posted to the Slack channel
Google meet somehow knows where to post back! Is this configured at the Google application (application id is provided via gid)? How can I configure my application for such behaviour? Where can I setup webhook url?
If we breakdown the request, we can see that url contains some parts of the gd payload:
THTJ27X6W - this is the first part of the gd payload
B01ABCD5GJF - last but one
E1MDm4DWcuVa0RbK5ZT9o5KD - the last part of the gd payload
and form-data contains:
hangout_id - this is in the gd payload after my name
hangout_url - obviously, this is the url for the new created meeting
How can I change it for my needs?
I created a new application at Google APIs dashboard (here console.developers.google.com/apis), but can't find any docs for this integration. There's Google+ Hangouts API in API Library, but it says Apps will continue to function until April 25, 2017..
I tried to approach it from another side:
In the API Library there's Google Calendar. I found mattermost-hangout app on GitHub (had to update it a bit, so it works with updated api). Here's how it works:
oauth2 for authorising at google (single account)
it handles POST request, which is meant to be received from Mattermost (triggered by a slash command),
creates a new calendar event using Google Calendar API (with conference),
takes hangouts url from the response and sends a new message in the Mattermost channel with invitation to join the meeting.
But it has some downsides:
you have to use one account to authorise all event creation events (yeah, it can be upgraded to authorise any number of users, but it'll be inconvenient. why to force anyone to provide access to their Google Account, when Google Meet authorisation just happens in browser, we don't need to create events)
account, used for auth, now has events in his calendar. of course, events can be deleted, but it's not the way.
Is there any documentation on utilising gid and gd params?
Generally, I want to find a way to configure a webhook in my app, so when Google Meet finds my application's ID in the gid query param, it looks at the app's config and sends a request to my app (previously configured endpoint (I assume it works this way)).
Of course there's a chance that it's some kind of internal API and it cannot be used by everyone, but I could not find any information on this.
In a Slack conversation, is it possible to click on a button to send a message to the Slack channel?
The Slack conversation could be:
The user types a word (or message)
A slackbot shows some text and two buttons
The user clicks on a button to send a TEXT message to the Slack channel
The Slackbot reacts on the 'action' message.
It is not possible to create an REST service for my Slackbot, because the Slackbot is behind a firewall. So, registering commands is not possible.
So sending a message as the result of a button click is needed. The Slackbot can react on that message.
I read that attachments could be a good way to do this, BUT the is 'outmoded'.
I tried to send an secondary attachment, which is outmoded, but that was not possible.
The next approach was adding a webhook. So pushing a button resulted in using the url, but that is of course not possible because I cannot send a POST request via a simple (get) url.
Please give a short example.
This will not work.
Every interactive feature (e.g. buttons) require your app to be able to receive POST requests from Slack through the public Internet. Since you say you can not provide that (e.g. behind a company firewall) you will not be able to use any interactive features.

Whenever my app posts ephemeral message to Slack channel (in response to a query by a user), I am unable to get the timestamp of my Slack app response. As I want to delete it once the user has made a selection using one of the buttons. Although I have subscribed to 'message.channels' event, I don't get a notification to my app whenever my app posts in the channel (in response to the user input), therefore, I am unable to get the timestamp of the message which I'll use to delete it. All I want is the timestamp of the message posted by my app so that I can delete it but I am unable to receive the timestamp. Please help!
For e.g. in Giphy app for Slack. Let's say the user invokes the app by calling '/giphy [dog]' where 'dog' is just an example of a search term. The app responds by sending a gif and user can either send it, shuffle to the next one or cancel it. I want a similar capability of cancelling the app response but I need the timestamp of the message in order to do so therefore I am asking for help.
Thanks.
Your approach can not work, because Slack is handling ephemeral messages differently from "normal" messages. They are only visible by one user and can not be modified by API methods (e.g. deletion).
But of course its possible to replace ephemeral messages. Here is how:
Your app can just reply to the interactive message request from Slack with a new message. That new message will by default override the original message including ephemeral messages.
You can reply in two ways:
Directly reply to the request from Slack with a message within 3 seconds
Send a message to the response_url from the Slack request within 30 minutes.
See here for the official documentation on how to respond to interactive messages.
This approach works both with interactive messages and slash commands.

I'm trying to have my backend create a poll for a given user and when the user responds to the poll receive the response on the backend. However I cannot find a way to do the second part with an API available.
I know I can use Incoming Webhooks to send a command to users slackbot channel: /poll .. ... ... however I'm unsure how to receive a response from when user selects one of the options in the poll.
OK, one approach would be
Slash command for the /pollcommand, it will send a request to your app every time a user enters the command
Your app can then sends the actual message containing the poll details back to the channel incl. message menus simply by responding to the slash request or with Web API e.g. chat.PostMessage
User chooses polls option from message menus. Chosen option is send back to your app by Slack.
This is just one approach. Alternatively you could also show the options as message buttons or open a Dialog for the user.
I would advise against using outgoing webhooks, since its no longer part of the main features (and slash commands and interactive menus will send a request directly to your app anyway). Also Web API / chat.PostMessage is better than Incoming webhooks.
