Plug for authenticating GraphQL requests using either API tokens or mobile session tokens.
|
|
|
|
Accepts two token types via Authorization: Bearer <token>:
|
|
- API tokens (prefixed with "towerops_") → sets current_organization_id + current_user
|
|
- Mobile session tokens → sets current_user only (no org_id)
|
|
|
|
Returns 401 Unauthorized if neither token type is valid.
