Add Slack as a social sign-in provider in Ory

Configuration for The Ory Network​

Follow these steps to add Spotify as a social sign-in provider to your project using the Ory CLI:

  1. Create a Slack OAuth Application.

  2. In the created app, set the redirect URI to:

    https://<ory-project-slug>.projects.oryapis.com/self-service/methods/oidc/callback/slack

  1. Create a Jsonnet code snippet to map the desired claims to the Ory Identity schema.

    local claims = {
      email_verified: true,
    } + std.extVar('claims');

    {
      identity: {
        traits: {
          // Allowing unverified email addresses enables account
          // enumeration attacks,  if the value is used for
          // verification or as a password login identifier.
          //
          // It's assumed that Slack requires an email to be verified to be accessible
          // via OAuth (because they don't provide a email_verified field).
          email: claims.email,
        },
      },
    }
danger

Don't save secrets such as API keys, credentials, or personal data directly in Jsonnet code snippets. Jsonnet code snippets used for data mapping aren't stored in an encrypted format in The Ory Network.

  1. Encode the Jsonnet snippet with Base64 or host it under an URL accessible to The Ory Network.

  2. Download the Ory Identities config from your project and save it to a file:

    ## List all available projects
    ory list projects

    ## Get config
    ory get identity-config <project-id> --format yaml > identity-config.yaml

  1. Add the social sign-in provider configuration to the downloaded config. Add the Jsonnet snippet with mappings as a Base64 string or provide an URL to the file.

    selfservice:
      methods:
        oidc:
          config:
            providers:
              - id: slack # this is `<provider-id>` in the Authorization callback URL. DO NOT CHANGE IT ONCE SET!
                provider: slack
                client_id: .... # Replace this with the OAuth2 Client ID provided by Slack
                mapper_url: "base64://<YOUR_BASE64_ENCODED_JSONNET_HERE>"
                # Alternatively, use an URL:
                # mapper_url: https://storage.googleapis.com/abc-cde-prd/9cac9717f007808bf17f22ce7f4295c739604b183f05ac4afb4t
                scope:
                  - identity.basic
                  - identity.email
          enabled: true

  2. Update the Ory Identities (Ory Kratos) configuration using the file you worked with:

    ory update identity-config <project-id> --file updated_config.yaml

Configuration for self-hosted instances​

Follow these steps to add Slack as a social sign-in provider when self-hosting Ory Kratos:

  1. Create a Slack OAuth Application.

  2. Set the redirect URI to URL that follows this pattern:

    http(s)://<domain-of-ory-kratos>:<public-port>/self-service/methods/oidc/callback/slack

  3. Create a Jsonnet code snippet to map the desired claims to the Ory Identity schema.

  4. Encode the Jsonnet snippet with Base64 or store it in a location available to your Ory Kratos instance.

  5. Add the social sign-in provider configuration to the Ory Kratos configuration. Add the Jsonnet snippet with mappings as a Base64 string or provide a path or an URL of the file.

tip

When running a self-hosted instance, you can pass the social sign-in provider configuration in the SELFSERVICE_METHODS_OIDC_CONFIG_PROVIDERS environment variable. For example:

SELFSERVICE_METHODS_OIDC_CONFIG_PROVIDERS='[{"id":"google","provider":"google","mapper_url":"<file_location>","client_id":"<client_id>","client_secret":"<client_secret>","scope":["openid","email","profile"],"auth_url":"https://accounts.google.com/o/oauth2/v2/auth","token_url":"https://www.googleapis.com/oauth2/v4/token","issuer_url":"https://accounts.google.com"}]'

Prevent having to log in after sign-up​

When adding social sign-in providers manually, remember to add the session hook to after/oidc/hooks. If you don't add this hook, users will have to log in again after signing up to get a session.

selfservice:
  flows:
    registration:
      after:
        oidc:
          hooks:
            - hook: session
