Returns an OpenAPI 3.0 Schema Object that describes the request body of POST /baas/Clients for the given
client type (individual or business). The schema reflects the onboarding configuration of your
integration: the fields, their types, allowed values and which of them are required.Request the schema when building the onboarding payload instead of hard-coding the field list, and do not
cache it for long: it changes when the configuration changes.Returns 403 Forbidden if your integration is not allowed to create clients of this type.
