WhatsApp HSM templates in WazzaBee: reaching customers outside the 24-hour window

WhatsApp HSM templates exist for the moments when a business has to message a customer first, or pick the conversation back up after the 24-hour support window has expired. In WazzaBee you can use those templates right inside the chat: the agent picks a Meta-approved template, fills in the {{1}}, {{2}} variables, checks the preview and sends the message.

This one is especially useful for medical centers, clinics, laboratories, service companies, training centers, online stores and sales departments that run on WazzaBee, Bitrix24 or any other CRM.

The 24-hour window, and why you can't work around HSM

The WhatsApp Business Platform has two distinct modes of talking to people:

The moment the customer replies to your HSM message, a new 24-hour window opens. Inside it the agent can go back to ordinary messages: clarify details, answer questions, send extra materials.

Meta's template categories

Meta sorts WhatsApp Business Platform messages into categories. The category drives how the template is reviewed, what it costs and what the text is allowed to say.

Medical centers, laboratories, service companies and most CRM notifications land in the Utility category. But if the text carries an ad, a discount, an upsell or a call to buy, Meta will reclassify the template as Marketing.

How it works in WazzaBee

1. You create an HSM template for a WABA channel in WazzaBee.
2. The template goes to Meta for review.
3. Once it reaches APPROVED, it shows up in the list of available templates.
4. In the chat, the agent hits the templates button, picks the HSM template and fills in the variables.
5. WazzaBee shows a preview of the message and sends the template through your WABA channel.

Variables are what make it personal: the customer's name, the appointment date, an order number, an invoice amount, a payment link or a download link.

Hello, {{1}}!
Your lab results from {{2}} are ready.
You can download them here: {{3}}

At send time the agent or the CRM fills in the values:

{{1}} = Aigerim
{{2}} = 22.06.2026
{{3}} = https://clinic.kz/r/8f3a...

Scenario 1. A medical center sending lab results

The textbook case for a clinic or a laboratory: the patient gives a sample in the morning, the result is ready that evening or the next day. The 24-hour window may well be closed by then, yet the patient is waiting to hear from you.

Template we recommend

Hello, {{1}}!
Your lab results from {{2}} are ready.
You can download the document via this secure link: {{3}}

If you have any questions, just reply to this message and our front desk will help.

What goes into the variables

How to keep it safe

• Never put a diagnosis, test values or any sensitive medical data into the WhatsApp text.
• Keep the notification neutral: "your results are ready", "the document is available".
• The link must be protected: a token, an expiry date, and no indexing by search engines.
• Better still, gate the document behind a check: date of birth, national ID, an SMS/WhatsApp code or a login to the personal account.
• Never use public links like /results/ivanov.pdf.

Scenario 2. Appointment reminders

Reminders cut no-shows. If the patient booked several days ago, an ordinary message is already off the table. An HSM template solves it the right way.

A template for a clinic

Hello, {{1}}!
A reminder about your appointment at {{2}} on {{3}} at {{4}}.

Address: {{5}}
If you need to reschedule, just reply to this message.

Filled in, it looks like this

{{1}} = Sergey
{{2}} = Amanat Medical Center
{{3}} = 25.06.2026
{{4}} = 15:30
{{5}} = Almaty, Abay St 10

Buttons

If the template supports buttons, quick replies are a natural fit:

• Confirm
• Reschedule
• Cancel

The moment the customer taps a button or types a reply, the 24-hour window opens and your front desk can carry on the conversation normally.

Scenario 3. Invoices, payment links and top-up payments

This one fits clinics, schools, service companies, online stores and B2B services. The customer has placed an order or booked a service, but the payment request goes out later.

Template

Hello, {{1}}!
Invoice #{{2}} for {{3}} is ready.
You can pay it here: {{4}}

We'll update the status of your request automatically once the payment goes through.

What matters here

• If the message relates to a specific order, booking or service, it is normally Utility.
• Don't slip advertising into this kind of template: "and while you're here, buy this", "today only"; that turns it into Marketing.
• The payment link should lead to a clear page showing the amount, what it's for and the company name.
• Once payment lands, you can trigger an automatic "payment received" message.

Scenario 4. A service center reporting repair status or order readiness

The customer has left a phone, a car, some equipment or documents with you. A few days later you need to report the status. The 24-hour window is long gone, so HSM it is.

Status template

Hello, {{1}}!
Status of your request #{{2}}: {{3}}.

Note from our specialist: {{4}}
If you'd like more detail, just reply to this message.

Example statuses

• "Diagnostics complete"
• "Waiting for you to approve the cost"
• "Your order is ready for pickup"
• "We need some extra details"

If you need an approval, add a link to the request page or an "Approve" button. Once the customer answers, the agent continues in the ordinary chat.

Scenario 5. A training center sending materials, schedules and homework

Templates earn their keep in schools, courses, kids' centers and corporate training. A student signs up for a course, and materials have to go out week after week.

Class materials template

Hello, {{1}}!
Materials for the "{{2}}" class are available here: {{3}}

Next class: {{4}} at {{5}}.
If you have questions about the assignment, just reply to this message.

How to keep Utility from turning into Marketing

• Write only about the current course, class or service the customer is already receiving.
• Don't bolt on promotions or offers to buy another course.
• To sell additional courses, build a separate Marketing template with a proper opt-in.

Scenario 6. Delivery, orders and bookings

For online stores, food delivery, flower shops, salons and travel, HSM templates cover every status that matters: confirmed, rescheduled, ready, collected, delivered.

Template

Hello, {{1}}!
Your order #{{2}} {{3}}.

Date: {{4}}
Order details: {{5}}
If anything needs changing, just reply to this message.

{{3}} carries the status: "has been confirmed", "is with the courier", "is ready for pickup", "is awaiting payment".

Scenario 7. Winning a customer back and selling again

If the point of the message is to bring a customer back, offer a discount, invite them for a follow-up visit or sell an extra service, you're no longer in Utility territory; that's Marketing.

A Marketing template for a clinic

Hello, {{1}}!
{{2}} has a consultation slot available for you in {{3}}.
You can book it here: {{4}}

If you'd rather not receive offers like this, reply "Stop".

Rules for Marketing

• You need the customer's consent to marketing messages.
• Give people an obvious way out: "Stop", "Unsubscribe", an opt-out button.
• Don't send too often: a high complaint rate drags down the quality rating of your templates and your number.
• Segment your base: 500 relevant messages beat 5,000 random ones.

Sending HSM templates straight from the WazzaBee chat

1. Open the Chats section.
2. Pick the conversation you need, or create a contact manually.
3. Click the templates button in the message input field.
4. If the channel is a WABA one, WazzaBee will show your approved HSM templates.
5. Choose a template.
6. Fill in the variables: name, date, amount, link, request number.
7. Check the preview.
8. Click Send.

If the template has no variables, WazzaBee sends it as is. If it does, the system will ask you to fill in every one of them before it goes out.

What WazzaBee's HSM messages and errors actually mean

Below are the real situations you'll meet in the WazzaBee interface. Feel free to forward this block to your agents and admins so they can tell at a glance what went wrong.

API responses an integrator may run into

When the send comes from a CRM, a robot or the API rather than from a human clicking in the interface, the integrator gets a technical response back. Worth knowing what each one means.

Sending HSM templates from Bitrix24 and CRM robots

HSM templates really come into their own in CRM automation. A robot in Bitrix24 or any other CRM can fire off a template when a deal, a booking or a request changes stage.

A Bitrix24 example: lab results are ready

1. The deal or smart process holds the fields: patient, phone, test date, link to the result.
2. When the stage flips to "Result ready", the robot fires.
3. The robot picks the WABA channel and the lab_result_ready HSM template.
4. The CRM maps the variables from the card's fields.
5. WazzaBee sends the template to the customer.
6. If the customer replies, the agent sees the conversation in WazzaBee or right inside Bitrix24.

Variable map

Other robots worth building

• Booking created → send an appointment confirmation.
• One day before the visit → send a reminder.
• Invoice created → send the payment link.
• Document ready → send the download link.
• Deal stalled for 3 days → send a gentle nudge, if you have consent.

How to write HSM templates Meta approves faster

A good template

Hello, {{1}}!
Your appointment on {{2}} at {{3}} is confirmed.
Address: {{4}}
If you need to reschedule, just reply to this message.

Why it works:

• the purpose is obvious;
• there's no spam;
• the variables sit in logical places;
• the customer understands why they got the message;
• there's a clear next step.

A bad template

{{1}}, open {{2}} right now, there's important information there!!!
Plus we've got discounts, promos and the best offers around: {{3}}

Why it fails:

• it's unclear who is writing and why;
• the tone is far too pushy;
• Utility and Marketing are mashed together;
• the variables can hide the point of the message;
• higher odds of a Meta rejection or customer complaints.

Rules for links inside templates

Links in HSM templates are useful, but they need a careful hand.

• Use your company domain or a recognizable service domain, not a random short link.
• Don't paste long technical URLs into the body when a button would do.
• For medical documents, use single-use or time-limited links.
• Never put personal data straight into the URL: full name, national ID, diagnosis, passport number.
• Test the link before you send: the customer must not land on a 404 or on somebody else's document.
• Give the download button plain wording: "Download results", "Open invoice", "Go to booking".

What to send outside the 24 hours, and what belongs in a normal chat

Checklist before you launch a template

• The customer has agreed to receive messages on WhatsApp.
• The category is right: Utility, Marketing or Authentication.
• There's no stray advertising in a template declared as Utility.
• Every variable is clear to the agent or the CRM robot.
• The links are safe and only ever open that one customer's data.
• The template has been proofread in every language you write to customers in, Kazakh first.
• You have a plan for handling the customer's reply.
• Agents know when to reach for an HSM and when a normal message will do.

Template names you can copy

The takeaway

HSM templates are the right tool for messaging people outside WhatsApp's 24-hour window. WazzaBee lets you use them by hand from the chat or automatically through Bitrix24 and other CRMs. The essentials: keep service notifications and marketing apart, keep sensitive data out of the message body, use secure links, and think your variables through in advance.

For clinics and laboratories the ideal starter set is five templates: lab results ready, appointment reminder, payment link, document ready, and rescheduling. That covers most of what a working day throws at you, without breaking Meta's rules and without calling every customer by hand.
