WhatsApp Business API for Appointments: Approved Reminder That Arrives Even Outside the Window

Outside the 24-hour window, only an approved template goes out. This rule separates the reminder that arrives from the one Meta simply doesn't deliver.

Green verification badge

Assisted process for obtaining the verified badge that increases trust and message open rates.

Account verification and official seal

Nexloo handles the business verification with Meta and the request for the badge. The client sees the company's name instead of a random number — and decides in seconds whether to respond.

No limit on connected devices

How many agents do you need at the same number, without a phone on the desk and without the instability of keeping a device connected all day long.

Approval of models accompanied

You write the model, the platform sends it to Meta, and shows the status. Rejections come with a reason, and adjustments are made before the campaign relies on them.

24-hour window controlled

Within the window, the conversation is free and without model costs; outside of it, only approved templates are sent. The platform shows the status of each conversation.

Delivery and read receipt

Sent, delivered, and read come as the status of each message. For billing and mandatory communication, this record is the difference between notifying and proving that you notified.

Click-to-WhatsApp ads

Meta campaigns that open a conversation go directly to the official number, with the source campaign tagged in the contact — and attribution stops being a guess.

Quality monitor of the number

Meta maintains a quality indicator on your number and limits sending when it drops. The platform monitors this indicator and alerts before the limitation.

Sending tier escalation

The daily conversation limit increases according to the number's history. The platform shows what step you are on and what is needed for the next one.

Migration of the number you already use

The current number can be migrated to the API while keeping customer contacts. There's no need to share a new number or restart the database.

What's changing

The reminder doesn’t go out without an approved template.

It's the most frequent discovery for those trying to remind clients via WhatsApp: outside the 24-hour window, free messages are not delivered. Without an API, the reminder simply doesn't happen.

The operation, compared

Scenario
  • Reminders delivered outside the 24-hour window — today9%
  • Reminders delivered outside the 24-hour window — with the API98%+89 p.p.
  • Missed reminders not delivered — today24%
  • Missed due to undelivered reminder — with the API6%−18 p.p.

Illustrative scenario, not customer measurements. The percentages are meant to compare the two ways of working and vary according to each company's process. The example considers an operation with a full schedule that relies on reminders the day before.

In practice

How the reminder starts being delivered

Three things need to be right for the reminder to arrive: the model category, the approval, and the time. The platform takes care of all three.

  1. The model is categorized

    Reminder is a utility template, not marketing — the right category changes approval and cost.

  2. The approval is given beforehand

    The text goes to the Meta in advance, and the refusal comes with the reason for adjustment.

  3. The sending respects the schedule

    The schedule triggers the day before, within the range where the customer can respond.

  4. The response opens the window.

    Those who respond unlock 24 hours of free conversation — and rescheduling happens right there.
