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

  1. Create a Twitch OAuth2 Application.

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

  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 Twitch.
    [if 'email' in claims && claims.email_verified then 'email' else null]:,

    Twitch provides an OIDC discovery URL, but it doesn't support the openid claim and returns an access_token only. Ory sends requests to Twitch's /me API and adds the user info to std.extVar('claims').


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.

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

    cat your-data-mapping.jsonnet | base64
  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
  3. 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.

    - id: twitch # this is `<provider-id>` in the Authorization callback URL. DO NOT CHANGE IT ONCE SET!
    provider: generic
    client_id: .... # Replace this with the OAuth2 Client ID provided by Twitch
    client_secret: .... # Replace this with the OAuth2 Client Secret provided by Twitch
    mapper_url: "base64://{YOUR_BASE64_ENCODED_JSONNET_HERE}"
    # Alternatively, use an URL:
    # mapper_url:
    - openid
    - user:read:email # required for email and email_verified claims in the near future
    requested_claims: # explicitly request email and email_verified claims because twitch doesn't add them by default
    essential: true
    essential: true
    enabled: true
  4. Update the Ory Identities configuration using the file you worked with:

    ory update identity-config {project-id} --file identity-config.yaml


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
