Templates are per account: a template created on an account can be sent from every number on it and from no other. Use `whatsappAccount.id`, its `alias` (the name the team gave it, e.g. "Soporte") or any of its numbers to choose where to create a template. ## OpenAPI ````yaml /api-reference/openapi.json get /api/v1/whatsapp-numbers openapi: 3.1.0 info: 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. servers: - url: https://www.useboom.ai description: Production - url: https://dev.useboom.ai description: Development (sandbox — use a development organization API key) security: - bearerAuth: [] paths: /api/v1/whatsapp-numbers: get: tags: - WhatsApp templates summary: List numbers description: >- List the WhatsApp numbers connected to your organization, each with the WhatsApp account (WABA) it belongs to.
