  title: Stytch B2B Discovery Intermediate Session Exchange
  summary: Authenticate a discovery magic link, list discovered organizations, then exchange into one.
  description: >-
    An organization-selection login flow for B2B apps where the member already
    belongs to one or more tenants. The workflow authenticates a discovery email
    magic link to obtain an intermediate session and the list of organizations
    the email is a member of, then exchanges that intermediate session into a
    chosen organization to produce a full member session. Every step spells out
    its request inline so the flow can be read and executed without opening the
    underlying OpenAPI description. All calls authenticate with HTTP Basic auth
    using your Stytch project_id as the username and secret as the password.
