Web Chat

Embeddable widget with a one-line script and a secure public key.

WhatsApp

Telegram

Telegram bot channels wired into the same unified inbox.

Facebook

Every channel gets a regenerable pk_live_… public key, origin allow-listing, and signature-verified, idempotent webhooks.

REST API

Headless Customer Service

Build completely custom support experiences. Every capability available in the Indexu interface is also accessible via our versioned REST API under /api/v1.

  • Personal Access Tokens: secure API authentication with granular scopes.
  • Custom Help Centers: fetch knowledge base articles to render in your own UI or native mobile app.
  • Tickets & Conversations: create tickets, reply, and triage with AI endpoints directly from your product.
Create a Ticket
curl -X POST https://api.indexu.app/v1/tickets \

    "body": "Need help configuring my webhook endpoints.",
