[QUERY] How to fetch email from user ID?

[gautham acharya]

Question

I have the following workflow:

const inputForm = SampleWorkflow.addStep(
  Schema.slack.functions.OpenForm,
  {
    title: "New Request",
    interactivity: SampleWorkflow.inputs.interactivity,
    submit_label: "Submit request",
    fields: {
      elements: [{
        name: "user",
        title: "User",
        type: Schema.slack.types.user_id,
      },
...

This is used to create a GitLab issue ticket. I would like to insert the requesting user's email in the issue ticket, but I only have the Slack User ID, not the email. Is there a way to extract the email without another web API call? If not, is there an easy way to authenticate with the web API without using a token, since the deno-slack-sdk is already authenticated?

You can use the users.info API, but note that your app should also ask for the users.read:email scope to retrieve this part of the user profile.

If this resolves you issue, we appreciate it if you could close the issue. Otherwise, we're here to help.

How do I authenticate to this API in my deno-slack-sdk app?

I am doing this in local development right now. I am able to run everything via slack login and slack run. Do I need to set an additional token as an env var? Or does the SDK have some way of accessing the token that is passed in by authentication via the CLI?

@gacharya the scopes for your bot can be set in your app manifest and should be automatically requested when you re-install (re-run) the app in your workspace. A bit more info on manifests can be found in these docs!
