  title: Boom API
  version: 1.0.0
  description: >-
    Boom's public REST API — one uniform surface over every platform capability.
    CDP: upsert people and custom objects, define object and relationship types,
    link and unlink relationships, and record behavioral events — one record per
    request or up to 1000 per request via the `/batch` endpoints. Segments: read
    (list, read, membership) and full authoring — discover the filterable
    catalog, validate a filter, create and update segments, preview match
    counts, and trigger evaluation. Initiatives: create and configure outreach
    initiatives, link WhatsApp templates, drive the lifecycle (launch, cancel,
    archive), and read collected-data summaries. Participants: enroll people
    into an active initiative, track their status, read conversation
    transcripts, and stop outreach. Journeys: read-only access to always-on
    message flows and their metrics. WhatsApp templates: list your WhatsApp
    numbers and list, read, and create message templates. The same capabilities
    are exposed as MCP tools with identical schemas.
