  title: Mailchimp Find Campaign and Pull Its Report
  summary: Search campaigns by query, then retrieve the report for the first match.
  description: >-
    A find-then-act reporting flow. The workflow searches campaigns by a query
    string and branches on whether any matched: when a campaign is found it
    pulls the full report (sends, opens, clicks) for the first match, and when
    none match it ends. The matched campaign id threads from the search step
    into the report lookup. Authentication uses HTTP Basic auth with any
    username and your Mailchimp API key as the password.
