Linear

Linear OAuth2. No PKCE, no id token. User info comes from Linear's GraphQL API.

Configure

from better_auth import BetterAuth
from better_auth.oauth.providers_ext import Linear

auth = BetterAuth(
    secret=...,
    social_providers={
        "linear": Linear(client_id="…", client_secret="…"),
    },
)

Or name-keyed (no import):

auth = BetterAuth(
    secret=...,
    social_providers={
        "linear": {"client_id": "…", "client_secret": "…"},
    },
)

Options

Field	Type	Default	Notes
client_id	str | list[str]	required
client_secret	str	required

All shared ProviderConfig options apply.

Notes

• Default scopes: read.
• Register {base_url}{base_path}/callback/linear as the callback URL in the Linear OAuth application.
• User info is a GraphQL query — POST https://api.linear.app/graphql with a viewer { id name email avatarUrl … } query, not a REST GET. A response without viewer rejects the sign-in.
• Linear never returns an email_verified claim — mapped as False.
