v0.15.2

Transactional Template API and Webhooks

Adds utility-first transactional template sends, receipt templates, and the inbound webhook configurator foundation.

What's new in v0.15.2


Transactional template API


  • Added POST /api/v1/template-sends for API-key authenticated, workspace-scoped WhatsApp template sends.
  • Sends can target recipients by phone/external id, use approved UTILITY templates, and fill body variables, URL button variables, and DOCUMENT header PDF parameters.
  • Idempotency support prevents duplicate external-system sends from creating duplicate messages.

Receipt template options


  • Added starter utility templates for receipt links (Option A URL button) and PDF/document receipts (Option B DOCUMENT header) in Italian and English.
  • Added implementation guidance for payment receipt and instalment receipt integrations.

Inbound webhook foundation


  • Added tenant-managed inbound webhook configs with generated URLs, HMAC verification, dry-run defaults, one-time secret reveal, and run logs.
  • Added Settings > Integrations > Webhooks & API for creating and managing inbound webhook configs.
  • Verified live webhook runs can execute the transactional template-send service; dry-run remains the default.

Safety and compliance


  • Marketing templates are blocked by default for transactional API/webhook automation.
  • Webhook secrets are not accepted in query strings.
  • Invalid signatures do not reserve verified idempotency keys.
  • Webhook run logs store redacted headers, payload shape metadata, and sanitized mapped-request diagnostics rather than raw customer payloads or template variable values.
