New Features

Sign in with Slack (OpenID Connect)

Sign in with Slack helps users log into your service using their Slack profile. The platform feature was recently upgraded to be compatible with the standard OpenID Connect specification. With this version of slack-sdk, implementing the auth flow is much easier.

When you create a new Slack app, set the following user scopes:

oauth_config:
  redirect_urls:
    - https://{your-domain}/slack/oauth_redirect
  scopes:
    user:
      - openid   # required
      - email    # optional
      - profile  # optional

Check the Flask example in the repository. It does the following:

• Build the OpenID Connect comaptible authorize URL
  • slack_sdk.oauth.OpenIDConnectAuthorizeUrlGenerator helps you easily do this
  • OAuthStateStore is still available for generating state parameter value (it's available for nonce management too)
• WebClient can perform openid.connect.token API calls with given code parameter

If you want to know the way with asyncio, check the Sanic app example in the same directory.

Built-in Retry Handlers

This version introduces a built-in retry functionalities to the following API clients:

• slack_sdk.web.WebClient
• slack_sdk.webhook.WebhookClient
• slack_sdk.audit_logs.AuditLogsClient
• slack_sdk.scim.SCIMClient
• slack_sdk.web.async_client.AsyncWebClient (aiohttp/asyncio compatible)
• slack_sdk.webhook.async_client.AsyncWebhookClient (aiohttp/asyncio compatible)
• slack_sdk.audit_logs.async_client.AsyncAuditLogsClient (aiohttp/asyncio compatible)
