The WhatsApp Messenger Block for Moodle is a powerful communication plugin designed to bridge the gap between Moodle courses and students’ everyday communication habits. By integrating directly with the WhatsApp Business API, this block enables teachers and course managers to send official, structured WhatsApp messages to students enrolled in their courses—quickly, securely, and at scale.

WhatsApp is one of the most widely used messaging platforms in the world, and this plugin leverages that familiarity to improve student engagement, responsiveness, and course communication, especially for announcements, reminders, and important updates.

Purpose and Use Case

In many academic and training environments, students do not regularly check email or Moodle notifications. The WhatsApp Messenger Block solves this challenge by delivering messages directly to students’ WhatsApp accounts using their phone numbers stored in Moodle profiles.

Typical use cases include:

• Course announcements and updates

• Schedule changes or urgent notices

• Assignment reminders

• Exam notifications

• Personalized messages to individual students

Messages can be sent to individual students or all enrolled students in a course with just a few clicks.
