Set up WhatsApp reminders in Blastak

Objective

Configure your business reminders and learn how to check what was sent. Appointments are confirmed automatically by default; a reminder helps clients find their time and management link. Use this product guide after setting up your services and working hours.

Prerequisites

• A configured business with at least one active service, its duration and consistent working hours.
• Access to Settings and Calendar. The 24-hour reminder is included on every plan; the 2-hour reminder requires Solo, Pro or Premium.
• A correctly entered client phone number. For a Moroccan number, check the +212 prefix and the remaining digits.
• A configured business WhatsApp number if you want owner alerts. The business number and client number serve different purposes.

Steps

1. Open Settings and the booking workflow card. Under automatic reminders, check R1, the 24-hour reminder. It is enabled by default; keep it selected if you want this reminder.
2. On Solo, Pro or Premium, also select R2, the 2-hour reminder, if a second reminder suits your business. A locked control means your plan does not allow it.
3. Save the workflow and reload the settings to check that your selection was saved. The post-visit message is a separate setting: it follows an appointment marked completed, rather than reminding the client before the visit.
4. Open the appointment in Calendar. Check its service, time and status. A Premium request awaiting manual approval must be approved before it becomes confirmed and eligible for reminders.
5. Check the message history for this appointment. Distinguish a message waiting to be sent from one sent, delivered or failed. A confirmed appointment does not prove that its WhatsApp message was delivered.

Expected outcome

Your reminder settings are saved and you know where to check delivery. Messages contain the service, appointment time and a link to reschedule or cancel. Any reduction in missed appointments must be measured with your own clients; enabling a setting does not guarantee it.

Troubleshooting

• No reminder: check confirmed status, the reminder setting and your plan for the 2-hour reminder. A late booking or approval can occur after the relevant sending window.
• Sent but not delivered: check the number with the client and review the message status. If failure persists, contact support with the appointment reference; avoid repeated identical follow-ups.
• Wrong time: compare the calendar time with the message. Messages use the business timezone. Ask support to check its configuration if the times differ.
• Cancellation or reschedule: check the new status and time in Calendar. Cancelled appointments are no longer eligible for upcoming reminders; messages already sent may remain in the conversation.
