Add Discord as a social sign-in provider in Ory

Configuration for Ory Cloud

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

1. Create a Discord OAuth2 application.

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

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

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

   local claims = {
     email_verified: false,
   } + 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.
         //
         // Therefore we only return the email if it (a) exists and (b) is marked verified
         // by Discord.
         [if 'email' in claims && claims.email_verified then 'email' else null]: claims.email,
       },
     },
   }
   info

   Discord doesn't implement OpenID Connect. Ory makes a request to Discord's User API and adds the data to std.extVar('claims'). Not all fields are supported. Check the list of supported fields in the source code.

   The identify scope adds these fields:

   iss                 # always https://discord.com/api/v6/oauth2/
   sub                 # numeric discord user id
   name                # username + # + discriminator
   nickname            # username
   preferred_username  # username
   picture             # avatar url
   locale              # user locale

   The email scope adds these fields:

   email               # user email
   email_verified      # whether email is verified

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 Cloud.

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

5. Download the Identity Service config from your Ory Cloud 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

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: discord # this is `<provider-id>` in the Authorization callback URL. DO NOT CHANGE IT ONCE SET!
               provider: discord
               client_id: .... # Replace this with the OAuth2 Client ID provided by Discord
               client_secret: .... # Replace this with the OAuth2 Client Secret provided by Discord
               mapper_url: "base64://<YOUR_BASE64_ENCODED_JSONNET_HERE>"
               # Alternatively, use an URL:
               # mapper_url: https://storage.googleapis.com/abc-cde-prd/9cac9717f007808bf17f22ce7f4295c739604b183f05ac4afb4
               scope:
                 - identify
                 - email
         enabled: true

7. Update the Ory Identity Service (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 Discord as a social sign-in provider when self-hosting Ory Kratos:

1. Create a Discord OAuth2 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/discord

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
