Oriel Chat Engine
Built on the WhatsApp Business Platform

WhatsApp for businesses that actually reply.

A shared team inbox, broadcasts to customers who asked to hear from you, booking forms that live inside the chat, and reminders that arrive before the appointment does.

Opt-out is enforced by the software, not by remembering. Reply STOP and we stop.

What it does

Four things, done properly.

Rather than twenty, done nearly.

A shared inbox

Your whole team answers one WhatsApp number, without passing a phone around. Conversations are claimed, so two agents never send one customer two different answers.

Broadcasts that respect consent

Send an approved template to a segment of your customers. Anyone who opted out is excluded when the audience is built — and again at the moment of sending.

Booking inside the chat

Customers pick a slot on a form inside WhatsApp. It syncs with Google Calendar both ways, and the same slot cannot be sold twice.

Reminders

“Your appointment is tomorrow at 3.” Sent 24 hours and 1 hour before — and never to someone who opted out. A booking is not consent to be marketed to.

The shared inbox

Two agents, one customer, one answer.

A conversation is claimed before it is answered — atomically, in the database. Two agents clicking “assign to me” in the same second cannot both win, so a customer never gets two different answers to one question.

And the 24-hour window is enforced: outside it, WhatsApp accepts a free-form reply and then silently never delivers it. We refuse it instead, and tell the agent to use a template.

Who we are

Oriel Inc., Gurugram.

Oriel Chat Engine is built and operated by Oriel Inc., registered in India at 599, 17B, Phase 1, Surat Nagar, Gurugram, Haryana, India. We are a WhatsApp Business Solution user building on Meta’s WhatsApp Cloud API.

We are a processor, not the owner of your customers’ data. When a business uses Oriel Chat Engine, that business is the custodian of its own contacts. We hold and process that data on their instructions.

Message history is kept for 90 days and then permanently deleted. Anyone can ask us to delete their data — here is exactly how — and we complete it within 30 days.

Engineering

The boring parts, done right.

The things that never sell a product, and lose you one when they are missing.

Encryption at rest

Access tokens and keys are ciphertext in the database. A dump yields nothing usable.

Opt-out · checked twice

Once when the audience is built, and again at the instant each message is sent.

Double-booking · impossible

Enforced by a database constraint, not by a check somebody might forget. Two customers, one slot, exactly one winner.

Audit trail

Who viewed which customer’s file, who launched what, and what was deleted, when.

Two-factor for admins

An account that can broadcast to 40,000 people needs more than a password.

Retention · 90 days

Message history is permanently erased — the files too, not just the rows.

Tenant isolation · fail-closed

A query that names no business does not return everybody’s data. It refuses to run.

Delivery · never silent

WhatsApp accepts messages it will never deliver. We refuse those before they are sent, rather than reporting a success.

Bounded by design

A 200,000-contact import costs the same memory as a 20-row one. Streamed, chunked, measured.
