  }}

  ## WhatsApp API v2

  Bulkit now offers native WhatsApp integration for automated notifications, customer support, and high-throughput broadcasts:

  - **Direct Text Messaging**: Send WhatsApp messages using `POST /api/v2/messages/whatsapp`.
  - **Media & Documents**: Stream media attachments up to 50MB via remote URL or direct multipart file upload (`images`, `videos`, `audio`, `PDF documents`).
  - **Bulk Broadcasts**: Dispatch personalized campaigns with curly brace placeholders (`{first_name}`) and custom variable substitution.
  - **Inbound Message Streaming**: Query chat history and receive inbound customer replies with decrypted media downloads.
  - **Device Session Management**: Real-time QR code linking and connection health monitoring (`/api/v2/whatsapp/status`).

  ## Account-Level Shared Webhooks

  Webhook configuration has been simplified:

  - **Dedicated Webhooks Tab**: Set global **DLR Webhook URL** and **Inbox Webhook URL** under `/api-keys` across all keys.
  - **No Webhook Secrets**: Removed complex signing secrets in favor of frictionless integration.
  - **Standardized Headers**: Webhook payloads are tagged with `X-Bulkit-Webhook-Event` (`sms.delivered`, `sms.failed`, `sms.blacklisted`, `whatsapp.receipt.updated`, `sms.received`, `whatsapp.message.received`).

  ## High-Precision Float Balances & API v2 Refinements

  - **Float Wallet Balances**: Account credit balances now return exact floating-point numbers (e.g. `2.97 KES`), supporting fractional micro-billing.
  - **Simplified API Key Creation**: Generating new keys only requires a descriptive Key Name.
  - **Dedicated Single SMS Endpoint**: OTPs and alerts can now be posted directly to `POST /api/v2/messages/sms` with a single `mobile` string.
  - **UUID & Flex Shortcode Support**: `sender_id` seamlessly accepts both modern UUID strings and legacy shortcode integers.

  ## Outbox filtering improvements

  The SMS outbox gained improved filtering for:

  - network
  - sender ID
  - single date
  - date range
  - sort order

  ## Notifications improvements

  Dashboard notifications now better reflect SMS sent and failed events, with clearer unread counts and better status visibility.

  ## Message rendering consistency

  Personalized SMS placeholders are now rendered earlier in the send flow so outbox and history views reflect final message content more reliably.
