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

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.
