How to get a slack user by email using users.info API?

Question

I'm trying to use Slack's users.info API to retrieve users information, but I need to find users by email, is there a way to do that?

Solution 1

Yes!

https://slack.com/api/users.lookupByEmail

Using this we can find a user if email id is available.

Solution 2

Currently you can only look up users with users.info by their ID.

An alternative solution to your problem would be to call users.list and filter within your client by the profile.email for whichever email you're looking for.

Solution 3

An undocumented API can do this job: https://slack.com/api/auth.findUser?team=&email=&token=xoxp-XXXXXXXXX

Solution 4

If this is being done on behalf of a Slack slash command, one can configure the command to expand @username, #channels, etc...

This can be done under the command section of the Slack app. See the following screenshot:

Solution 5

This was useful for me. My setup: I am part of an enterprise, so the legacy token does not have users:read.email scope to it.

Solution: I created an app with users:read.email scope and other scopes needed. Got the app approved from my admin, installed the app to my workspace, retrieved the OAuth token, used it with https://slack.com/api/users.lookupByEmail.

Thanks. Here is a regular expression to find and parse the escaped usernames: \<@([^\|]+)\|([^\>]+)\>
