  title: Salla Upsert Customer
  summary: Find a customer in a page of results and update them, otherwise create a new customer.
  description: >-
    A CRM synchronization pattern for a Salla store. The workflow reads a page
    of customers, branches on whether the directory already holds any
    customers, and either updates the first matched customer in place or
    creates a brand new customer record. Each step spells out its request
    inline so the flow can be read and executed without opening the underlying
    OpenAPI description.
