Slack

Ory Console

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

1. Go to Authentication → Social Sign-In in the Ory Console.

2. Click the switch next to the Slack logo to start the configuration.

3. Copy the Redirect URI and save it for later use.

4. Create a Slack OAuth Application.

5. After creating the new application, navigate to the OAuth & Permissions section of the registered application in Slack and add the saved Redirect URI from Ory to the Redirect URLs of the registered application.

6. Navigate to the Basic Information section of the registered application in Slack and copy the following data to the corresponding fields in the form in the Ory Console:

   • Client ID
   • Client Secret

7. In the Scopes field of the form in the Ory Console, add the following scopes:

   • identity.basic
   • identity.email

8. In the Data Mapping field of the form in the Ory Console, add the following Jsonnet code snippet, which maps 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 Ory Network.

9. Click Save Configuration.

Ory CLI

Follow these steps to add Slack 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://$PROJECT_SLUG.projects.oryapis.com/self-service/methods/oidc/callback/slack

3. 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 Ory Network.

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

   cat your-data-mapping.jsonnet | base64

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

   ## List all available workspaces
   ory list workspaces
   
   ## List all available projects
   ory list projects --workspace <workspace-id>
   
   ## Get config
   ory get identity-config --project <project-id> --workspace <workspace-id> --format yaml > identity-config.yaml

6. 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

7. Update the Ory Identities configuration using the file you worked with:

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

Troubleshooting

When you add a social sign-in provider, you can encounter common problems such as:

• Redirect URI mismatch
• Redirect loops during registration
• Domain verification issues
