danger

Slack requires that the redirect URL of your app uses https, even for local development. An easy workaround for this is using a service like ngrok that creates a secure tunnel to your app, using https. Remember to set the url as NEXTAUTH_URL as well.

You can override any of the options to suit your own use case.

Example​


import SlackProvider from "next-auth/providers/slack";...providers: [  SlackProvider({    clientId: process.env.SLACK_CLIENT_ID,    clientSecret: process.env.SLACK_CLIENT_SECRET  })]...
