notes: >-
  bexio supports two auth styles, both presented as an Authorization: Bearer
  token against https://api.bexio.com/2.0. (1) OAuth 2.0 Authorization Code /
  OpenID Connect via the Keycloak realm at https://auth.bexio.com/realms/bexio
  for user-delegated app access. (2) Personal Access Tokens (PAT) for
  server-to-server access. Fine-grained OAuth scopes gate each module
  (contact_show/edit, kb_invoice_show/edit, accounting, project_show/edit,
  payroll_employee_show/edit, etc.). offline_access grants refresh tokens.
