# Let your systems talk on WhatsApp: WhatsApp API for developers in Hong Kong

**Your POS, online shop or app sends the WhatsApp message; your team sees it, and every reply, in EliteTeQ Inbox.**

The EliteTeQ API connects your own software to the WhatsApp Business number in your inbox. Send order updates and receipts with approved templates, add leads from your website, and get a webhook the moment a customer writes back. There is no Meta developer app to set up yourself: the number is already connected in EliteTeQ Inbox. It works with your +852 number and customers anywhere in Hong Kong.

- REST API with JSON, keys and scoped permissions
- Signed webhooks for every message and contact change
- Free sandbox with 1,000 requests a month
- Business plan includes 10,000 requests a month

## Where WhatsApp still needs a person typing

> Our POS knows when an order is ready, but someone still types the WhatsApp message.

Your POS calls the API with an approved template, such as order_ready, and the customer gets it at once. The message and any reply show in the inbox for your team.

> Leads from our website form never reach the WhatsApp team.

Add each lead with the API. It lands on the pipeline in the first stage, with its source, ready for a teammate to message.

> Our system has no idea what customers say on WhatsApp.

Subscribe to the message.received webhook. Every customer message is posted to your system, signed so you know it came from EliteTeQ, and retried if your server is down.

### What should your system say on WhatsApp first?

Tell us what you want to connect: a POS, an online shop or your own app. We switch on API access and help you send your first template.

## How to start with the API

The API is in early access: message us and we switch it on for your account.

1. **Create a test key** — In Settings → Developers, create an et_test_ key with only the permissions you need. Test keys check everything but never save or send.
2. **Build against the docs** — Use the API reference with its built-in console, the OpenAPI file or the Postman collection.
3. **Switch to a live key** — Swap in an et_live_ key. Messages now go to real customers from your connected WhatsApp number.
4. **Watch usage and webhooks** — See every request with its ID, and test or resend webhooks, in Settings → Developers.

## What is the EliteTeQ API?

The EliteTeQ API lets your own software use the WhatsApp Business number connected to EliteTeQ Inbox in Hong Kong. With an API key you can add and update contacts, move them through pipeline stages, send text messages or approved WhatsApp templates, read message history, and receive signed webhooks when customers write, read or reply. Plans start with a free sandbox; API Starter is $29 a month for 50,000 requests.

- Contacts, groups, stages and messages over REST
- WhatsApp, Messenger and Instagram from one API
- 8 webhook events, signed and retried
- Keys limited to the permissions you choose

## What you can build

The same inbox your team uses, reachable from your code.

### Send messages from your system

Send a text inside the 24-hour window, or an approved template any time: order ready, payment received, delivery on the way. The answer tells you if it was sent, is waiting, or failed and why.

- Text or approved templates with parameters
- Delivery and read updates arrive as webhooks
- Messages show in the inbox next to your team’s replies

### Keep contacts and the pipeline in sync

Create and update contacts, set their stage, category and tags, or update many at once. Your CRM, shop or website and the inbox stay the same.

- Create, search and update contacts
- Move leads between stages
- Batch updates and groups

### Hear about every conversation

Webhooks post to your server when a contact is created or updated, a chat is assigned, or a message is received, sent, delivered, read or fails.

- Signed with your webhook secret
- Retried after 1, 5, 15 and 60 minutes
- Test and resend from Settings → Developers

## Typing it by hand vs the API

The message is the same; nobody has to remember to send it.

| By hand | With the EliteTeQ API |
|---|---|
| Someone copies the order number into WhatsApp | Your system sends the template the moment the order is ready |
| Website leads sit in an email inbox | Each lead lands on the pipeline at once |
| No record of WhatsApp in your own system | Every message arrives by webhook |
| One shared login for the integration | Separate keys, each with only the permissions it needs |

## EliteTeQ Inbox in Hong Kong

The API sends from your connected +852 WhatsApp Business number, so customers in Hong Kong see your business name as usual. Meta’s charges for template messages are billed to your Meta account, separately from API requests.

In Hong Kong, WhatsApp is the everyday messaging app, and customers use it to book, ask and reorder. EliteTeQ Inbox lets a shop or service team share one number without stepping on each other’s replies.

Customers in Hong Kong write in Cantonese and English. Your team replies in the customer’s language inside the 24-hour window; template messages are created in English.

Office hours are set day by day for each number. A common setup in Hong Kong: weekdays open, Saturday mornings open, Sunday closed. Anyone who writes while you are closed gets your away message, at most once every 12 hours, and the chat waits at the top of the list for the morning.

- **Numbers:** +852 (e.g. +852 6000 0000)
- **Office hours:** Run on Hong Kong time (HKT)
- **Weekend:** Saturday and Sunday
- **Templates:** English
- **Price:** From $29 a month, in US dollars
- **Paying:** Card, charged in Kenyan shillings at the day’s rate

## Selling on WhatsApp in Hong Kong

Customers in Hong Kong pay with Octopus, FPS, PayMe, AlipayHK, cards and cash, so when a sale closes on WhatsApp the customer may confirm payment in the chat, and your team needs to see that message quickly.

## Questions businesses ask us

**What counts as a request?**

Every call your system makes to the API counts as one request, whether it reads or sends. Webhooks EliteTeQ sends to you don’t count, and Meta’s charges for WhatsApp template messages are separate.

**Is this Meta’s WhatsApp API?**

No. It is EliteTeQ’s API on top of the official WhatsApp Business Platform. Your number is connected once in EliteTeQ Inbox, so you don’t need your own Meta developer app, and messages sent through the API appear in the inbox for your team.

**Do we need an EliteTeQ Inbox plan?**

Yes. The API works on an active EliteTeQ Inbox account, and API plans are added on top. The Business plan includes 10,000 requests a month.

**Is there a free sandbox?**

Yes. Test keys check every request exactly like live keys but never save or send anything, with up to 1,000 requests a month.

**How fast can we call it?**

Each key allows 120 requests a minute. Above that, the API answers with a rate-limit error and the number of seconds to wait.

**Can we message any customer from the API?**

A free-form text needs the customer to have written in the last 24 hours on WhatsApp (7 days on Messenger and Instagram). Otherwise send an approved template, and only to customers who agreed to hear from you.

**Is the API available now?**

It is in early access. Message us on WhatsApp and we switch it on for your EliteTeQ Inbox account.

**Is there a WhatsApp API for businesses in Hong Kong?**

Yes. The EliteTeQ API lets software used in Hong Kong send WhatsApp messages from a connected +852 business number, add leads to the pipeline and receive webhooks when customers write. It runs on an EliteTeQ Inbox account: the Business plan includes 10,000 requests a month, and API Starter adds 50,000 for $29 a month.

**Can our POS or online shop in Hong Kong send WhatsApp order updates?**

Yes, with an approved template such as order_ready or delivery_update. Your system calls the API when the order changes, the customer gets the message on WhatsApp, and any reply lands in the inbox for your team. Meta’s charge for the template is billed to your Meta account at its rate for Hong Kong numbers.
