import { Slack } from "arctic";

const slack = new Slack(clientId, clientSecret, redirectURI);
const url: URL = await slack.createAuthorizationURL(state, {
	// optional
	scopes // "openid" always included
const tokens: SlackTokens = await slack.validateAuthorizationCode(code);

Get user profile

Add the profile scope. Optionally add the email scope to get user email.

const url = await slack.createAuthorizationURL(state, {
	scopes: ["profile", "email"]

Parse the ID token or use the userinfo endpoint. See example ID token claims.

const tokens = await slack.validateAuthorizationCode(code);
const response = await fetch("", {
	headers: {
		Authorization: `Bearer ${tokens.accessToken}`
const user = await response.json();
