Is this suited for github?

  • Yes, this is suited for github

Is your feature request related to a problem? Please describe.

The Better Auth Linear provider currently only supports user-centric OAuth flows.

Linear also supports app-actor authorization (actor=app in the authorization URL), which mints tokens that act as the application itself (not a user).
This flow is required for service accounts, agents, and automations, but the existing better-auth provider does not currently expose a way to request it.

Without support for actor=app:

  • All tokens are user-scoped.
  • Integrations cannot perform mutations (issue creation, comments, status changes) as the app.
  • Many automation and agent use cases are blocked.

Describe the solution you'd like

  1. Authorization param support

    • Option A: Add a generic authorizationParams?: Record<string,string> forwarded to createAuthorizationURL.
    • Option B: Add a Linear-specific option (e.g. actor?: 'app' | 'user').

  2. Support for non-user “app actor” flows

    • Make the provider resilient to tokens without a user profile.
    • Allow skipping user linking and return raw OAuth credentials.
    • Alternatively, expose a variant of the provider that does not assume user identity.

  3. Documentation

    • Explain how to enable actor=app.
    • Clarify the implications (no user identity).
    • Provide example usage for service accounts and automations.

Describe alternatives you've considered

Currently I have written a custom OAuth2 provider with Better Auth primitives that enables me to do this but I would love to take advantage of Better Auth instead.
