      summary: Create a campaign
      operationId: createCampaign
      description: Create and send or schedule a campaign. One of 'body' or 'template_id' is required. One of 'list_id' or 'segment_id' is required.
      x-ai-role: marketing_automation_specialist
      x-ai-description: The primary engine for launching marketing broadcasts. This endpoint allows for direct HTML injection, template usage, and sophisticated segmentation. It supports both immediate sends and future scheduling with dynamic list updates.
      x-ai-reasoning-instructions:
      - Validate that either `body` or `template_id` is present.
      - Validate that either `list_id` or `segment_id` is present.
      - If `send_date` is provided, ensure it is in `Y-m-d H:i:s` format and in the future.
      - Check if `sender_email` is a pre-verified sender for the account.
      - For large lists, advise calculating cost using `/addressbooks/{id}/cost` first.
      - If `is_test` is true, remind the user that only one `list_id` can be used.
      x-ai-responding-instructions:
      - Provide the new Campaign ID and its initial task status.
      - Clearly state if the campaign is a draft (status 26) or entering the send queue (status 13).
      - If scheduled, confirm the exact time it will be sent.
      - Highlight the estimated recipient count if provided in the response.
      x-ai-suggestions:
      - Monitor campaign statistics using `/campaigns/{id}`.
      - Check referral statistics with `/campaigns/{id}/referrals`.
      - 'Send a test campaign first by setting `is_test: true`.'

      operationId: sendCampaign
      x-ai-role: chatbot_campaign_manager
      x-ai-description: Initiates a broadcast message to all subscribers of a specific chatbot, either immediately or at a scheduled time. This is the primary activation endpoint for bot campaigns — it orchestrates message delivery across an entire subscriber base and supports segmentation via filters, making it suitable for targeted re-engagement, announcements, and transactional notifications. The `message_tag` and `message_notification_type` fields are critical for Facebook Messenger policy compliance and must be set correctly to avoid delivery failures.
      x-ai-reasoning-instructions:
      - Before sending, confirm the `bot_id` is valid and active — use the bot list endpoint if the user is unsure which bot to target.
      - 'Check whether `send_at` is required: if the user wants immediate delivery, omit it; if scheduling, validate that the datetime is in the future and formatted as Y-m-d H:i.'
      - Warn the user that `message_tag` is required for sending outside the standard 24-hour messaging window on Facebook Messenger — clarify the available tags and their policy implications.
      - 'If a `filter` is provided, validate the filter structure: `type` must be ''and'' or ''or'', and nested `expressions` must include valid `operator`, `field`, and `value` triples.'
      - Remind the user that `messages` must be a non-empty array and that each message's `content_type` determines the structure of `data` — text messages use `data.text`, images and carousels use `data.attachment`.
      - For carousel messages, ensure each element in `payload.elements` has at minimum a `title`; `buttons` are optional but require a valid `type` (e.g., `web_url`) and a `url`.
      - If no filter is specified, the campaign will be sent to all active subscribers of the bot — confirm this is intentional if the bot has a large audience.
      x-ai-responding-instructions:
      - Confirm whether the campaign was scheduled or sent immediately based on the presence of `send_at` in the request.
      - Reference the returned `Campaign` object ID so the user can track or manage the campaign later.
      - 'If the operation fails, explain the most likely causes: invalid `bot_id`, malformed message structure, or policy violation due to incorrect `message_tag`.'
      - Suggest using the campaign status endpoint to monitor delivery progress after a successful send.
      - If a filter was applied, summarize the targeting criteria used so the user can verify the intended audience.
      x-ai-suggestions:
      - Schedule the campaign with `send_at` during peak engagement hours for the target audience's timezone.
      - 'Use `message_tag: CONFIRMED_EVENT_UPDATE` for event reminders to stay within Messenger policy.'
      - Segment subscribers by tag using the `filter` object to avoid messaging disengaged users.
      x-ai-capabilities:
        confirmation:
          type: Recommended
          message: This action will broadcast a message to all matching subscribers of the selected bot. Confirm the target audience, message content, and send time before proceeding.
