Mentioning users via slack in webhooks

Question

I'm building somewhat integration github with slack, which will notify users (reviewers of pull request) and send them link in #general chat.

And I'm struggling with mentioning users, right now I found only one way to mention them: via username in Slack, however to know this username, I must ask person to give it to me. Mentioning via <@display_name> doesn't seem to work, even with link_names: 1 parameter.

Not sure what your issue might be, but I can confirm mentions work when adding the link_names: 1 (@username was used in the text of the message) – Ma

Answer 1

You can mention users through <@memberID> as text in the Slack webhook. This will post a username as a string.

For example, if there is a user named John with memberID UC6B12Z4N, then pass <@UC6B12Z4N> in the Slack webhook. This will mention @John with the correct link.

How to find my Member ID in Slack workspace?

Answer 2

If you have the email you can also use the syntax mentioned by @Achyut but just with the "email" part. At least for me that helps a lot as finding the user/memberId is somewhat annoying.

Email -> [email protected]

To the bot:

{
 "text": "Hello <@someuser>"
}

This works even if the user has another "alias" in their name.

this didn't work for me – Orthocephalic

how are you using it?, I have a working bot which tags users this way and it works like a charm – Bifoliate

Underrated answer. This worked for me. Either using a webhook or a web client – Dangelo

@AlejandroBarone There was a misunderstanding on my part, you dont use the slack handle you would type but the member ID. For me this was more about understanding how to get that. – Orthocephalic

In my test, it works only if you use it with your email. If you use someone else's email from your workspace, it will not mention them in Slack. – Gaga
