WhatsApp Business API Hong Kong

WhatsApp Business API in Hong Kong — set up, broadcast and automated replies, run for you

Most Hong Kong business closes on WhatsApp, but the WhatsApp Business app has hard limits: broadcast lists cap out, sharing one number across a team is awkward, and automated replies are basic. The API removes those limits — but the application, verification, template approval and per-message billing all need handling. This page sets out which part we do. Getting the enquiries in the first place is on Google Ads management.

We are not selling you a platform — we set it up and run it

Search for WhatsApp Business API in Hong Kong and you get a list of platform vendors. What they sell is a software licence; what you send, and whether anyone answers, is generally left to you.

Our role is different. We are a marketing agency: we connect the API, write templates that pass approval, design the automated reply flows, and then actually run the campaigns each month and read the numbers. You can stay on whichever platform you prefer — we take no licence margin.

It also means we will tell you when you do not need the API. If you send a few dozen messages a month, the WhatsApp Business app is enough, and the money is better spent on local SEO.

011. API application and setupMeta business verification, number application, and connection to your existing systems. Verification codes that never arrive and mismatched company documents are the usual blockers, and we handle them.
022. Broadcast messagingWith the API, broadcast is no longer capped by the app’s list limits. But messages are billed per conversation, and Hong Kong’s PDPO requires recipient consent — so we set up the list, the consent record and the opt-out together.
033. Automated replies and chatbotsCommon questions answered automatically, out-of-hours replies, booking flows that complete. The point is fewer missed enquiries, not hiding behind a bot.

The four parts we handle

From application through to monthly execution. The advertising side is costed on Google Ads pricing.

1. API application and setup

Meta business verification, number application, and connection to your existing systems. Verification codes that never arrive and mismatched company documents are the usual blockers, and we handle them.

2. Broadcast messaging

With the API, broadcast is no longer capped by the app’s list limits. But messages are billed per conversation, and Hong Kong’s PDPO requires recipient consent — so we set up the list, the consent record and the opt-out together.

3. Automated replies and chatbots

Common questions answered automatically, out-of-hours replies, booking flows that complete. The point is fewer missed enquiries, not hiding behind a bot.

4. Click-to-WhatsApp ads

Google and Meta ads that open a WhatsApp conversation directly, skipping the landing page. Suited to businesses that already close in chat.

What actually changes with the API

Broadcast is no longer capped

The app’s broadcast lists have a hard recipient cap. The API does not, but it bills per conversation instead.

A team can share one number

Several people can work the same number at once, instead of the history living on one handset.

Automated replies become usable

Not just an out-of-hours line, but a flow that can complete a booking or an enquiry.

Enquiries become countable

Each conversation carries a source, so you can see which ad or page produced the sale. See conversion rate optimization.

When this makes sense

You need to send at scale monthly

The broadcast lists have stopped being enough.

Enquiries are being missed

Too many messages, replies too slow, customers gone.

Several people share one number

The history sits on one phone and handovers are messy.

Your business already closes in chat

Clinics, retail, property — customers message before anything else.

Where this usually gets stuck

Four of them, all common. The first stops the most people.

Meta business verification fails

A company name, address or document that does not exactly match the business registration gets rejected. The fix is the paperwork, not resubmitting.

Templates rejected

Too promotional, wrong format, or variables misused. Rewriting is faster than retrying.

A list with no consent record

Hong Kong’s PDPO requires consent and an opt-out for direct marketing. A bought or scraped list puts the risk on you.

The API is live and nobody runs it

The most common waste: the licence is paid, but nobody writes, schedules or reads anything.

Not sure where to start?First, whether you actually need the API

How this is priced

Three parts, itemised, the same way as on Google Ads pricing.

Meta’s messaging charges

Billed per conversation and paid to Meta or the platform. It does not pass through us and we take no margin.

Platform licence

If you use a third-party platform, that is their fee. You can also go direct with Meta.

Our setup fee

One-off: application, verification, templates, flow design.

Our monthly fee

Fixed. Copy, scheduling, optimisation and reporting. Unrelated to how many messages you send.

How we work

01

1. First, whether you need it

We look at your monthly volume and how many enquiries are being missed. If you do not need it, we say so.

02

2. Application and verification

Business verification, number setup, and the first batch of templates submitted.

03

3. Flows and consent

Automated reply flows, the consent record for your list, and the opt-out.

04

4. Monthly execution and reporting

Campaign copy, scheduling and results — measured by cost per conversation and by sales.

Why us rather than a platform vendor

We do not sell licences

You pay the platform directly. We take no margin, so which one we recommend makes no difference to us.

We will tell you not to bother

Below a certain volume the API is just another fixed cost.

We are explicit about Hong Kong compliance

PDPO consent and opt-out are handled from the start, not after a complaint.

We also run it

Setup is not a handover. The copy, the scheduling and the reading of numbers are our job.

Measurement, not promises

What we show you each month

The measure is not how many messages went out; it is how many conversations became business. We track conversations by source, reply rate, and the conversation cost behind each sale.

We report the opt-out rate alongside it. A rising opt-out rate means the content or the frequency is wrong, and that matters more than volume sent. Sector specifics are on clinics and healthcare and retail.

  • Conversations, split by source
  • Reply rate and first response time
  • Conversation cost per sale
  • Opt-out rate, and why
  • Template approval rate

WhatsApp Business API in Hong Kong — common questions

What is the difference between the WhatsApp Business app and the API?+

The app is a free mobile application, fine for lower volumes, but broadcast lists are capped, sharing a number is awkward and automated replies are basic. The API removes those limits but requires application, verification and template approval, and bills per conversation.

Is there a limit on broadcast recipients?+

The app’s broadcast lists have a hard cap, and Meta has tightened the monthly sending allowance further in recent years. The API has no such list cap and bills per conversation instead, so the real limit becomes budget rather than headcount.

Is broadcast messaging legal in Hong Kong?+

It is permitted but governed by the Personal Data (Privacy) Ordinance. Direct marketing requires prior consent and a way to opt out. We set up the consent record and the opt-out alongside the campaign. We do not work from bought or scraped lists.

What do the messages cost?+

Billing is per conversation at rates Meta sets, which vary by conversation type and region and do change. You pay it directly to Meta or the platform; we take no margin. Our own charge is the setup fee and a fixed monthly fee.

What if Meta business verification fails?+

It is nearly always documentation: the company name, address or business registration not matching exactly what was submitted. Resubmitting does not help; the paperwork has to be corrected first. We handle that step.

Which platform do I need?+

Hong Kong has several WhatsApp Business Solution Providers, and going direct with Meta is also possible. We do not sell licences, so the recommendation follows your volume, your systems and your budget rather than a vendor relationship.

My volume is low — is it worth it?+

Usually not. Below a certain volume the API is just another fixed cost and the app is sufficient. We say so plainly and suggest putting the budget into local SEO or Google Ads instead.

Start with the clearest opportunity

First, whether you actually need the API

We look at your current monthly volume, how many enquiries are being missed, and what systems you already run — then tell you whether to move to the API or stay as you are, and what setup and monthly would cost if you do.
