WhatsApp template for clinics: appointment rescheduling

When a patient asks to reschedule an appointment, a quick and clear response prevents misunderstandings and shows that the clinic is on top of it. This template is to let them know that their appointment has been moved, with the new day and time, and to ask for confirmation. It is a transactional message (utility category in the Meta API), so it does not need marketing opt-in, but the patient must have started the conversation or have a prior appointment.

• {{1}}: patient's name (e.g., 'Maria')
• {{2}}: clinic name (e.g., 'San Martin Clinic')
• {{3}}: original appointment date (e.g., 'Monday, August 12')
• {{4}}: original appointment time (e.g., '10:30')
• {{5}}: new proposed date (e.g., 'Wednesday, August 14')
• {{6}}: new proposed time (e.g., '11:00')

1. 1Copy the message and replace variables {{1}} to {{6}} with the patient's details and the new appointment.
2. 2Send the message from WhatsApp Business (app or web) or from the Wando inbox, which connects to Meta's official API.
3. 3If you use Wando, load this template in the panel (templates section) and the AI will automatically suggest it when it detects that a patient asks to reschedule. You still always review and approve it before sending.

Remember: in the official WhatsApp API, this type of transactional message falls under the utility category and the template must be approved by Meta (it can take up to 48 hours). Do not use this text for promotions or offers. If the patient does not respond, you can send a reminder through another channel or call.

When to send this message (and when not to)

This message is to notify you of a shift change that you already decided on, not to negotiate. Sending it as soon as you know you have to reschedule, ideally with more than 24 hours' notice, gives the patient time to reorganize and reduces the chance they won't read it.

Don't send it if the appointment is for the same day and the office hours have already passed: in that case, call. Also don't use it to offer promotions (that's marketing and the template doesn't apply) or to ask for confirmation of an appointment that's still on: that's another message, not this one.

How to respond to the three most likely replies

When the patient replies, you need to have your response ready. These are the three most common ones and a model for each.

If they say yes, confirm with a short, clear message:

If they ask for another time, offer a concrete alternative instead of asking 'when works for you?':

If they ask why it was rescheduled, don't go into internal details. Reply honestly and without making things up:

• "Perfect, {{1}}! We'll see you on {{5}} at {{6}} at {{2}}. If anything comes up, let us know."
• "Got it, {{1}}. How about {{7}} at {{8}}? If not, tell us what day and time works for you and we'll find it."
• "Hi {{1}}, it was an internal scheduling issue. We reassigned you to {{5}} at {{6}} so you don't lose your appointment. Does that work?"

How to know if the message worked

The message worked if the patient confirms the new time, period. But they don't always reply directly, so pay attention to these signs.

If WhatsApp shows the double blue check and they don't reply, wait a few hours and call. If they don't read it, try another channel. In Wando, the statistics show you delivered, read, and replied messages, so you know whether you need to follow up or not.

Important: don't count the message being sent as a success. If the patient hasn't confirmed, the new appointment is not secured.

Why Meta may reject this template and how to fix it

Meta reviews templates to ensure they aren't spam. The most common rejections for this type of message are:

If they reject it, read the reason in the Meta or Wando panel, correct the text, and resubmit it. Don't insist with the same version: adjust what they asked for and try again.

• Lack of clarity: if it's not clear that it's a rescheduling notice, they'll reject it. Make sure the text explicitly says 'reschedule' or 'appointment change'.
• Mixing categories: if you add an offer or promotion, it becomes marketing and they'll reject it as utility. Keep the message purely informational.
• Poorly defined variables: if variables {{1}}, {{2}}, etc. aren't well described in the Meta panel, the template may not pass review. Complete the description for each one.

Formal and informal variants: when to use each one

The formal variant is for patients who are not familiar with the clinic or in more serious contexts, such as a first appointment or a patient referred by a health insurance provider. Use it when you don't know how the patient prefers to be addressed.

The informal variant is for regular patients or when the clinic already has a relaxed relationship. If the patient uses the informal 'you' or uses emojis, that's the one to go with.

If you're unsure, start formal and loosen up if the patient does. It's easier to go from formal to informal than the other way around.

Formal and casual variants: when to use each

The formal variant is for patients who aren't familiar with the clinic or in more serious contexts, like a first appointment or a patient referred by an insurance provider. Use it when you don't know how the patient prefers to be addressed.

The casual variant is for regular patients or when the clinic already has a relaxed rapport. If the patient uses informal language or emojis, that's the one to go with.

If you're unsure, start formal and relax if the patient does. It's easier to go from formal to close than the other way around.
