Overview

Twilio Gateway integration in openSIS allows institutions to configure communication services for:

• SMS messaging
• WhatsApp messaging

By connecting Twilio credentials with openSIS, institutions can automate communication workflows and send notifications directly from the platform.

Twilio acts as the communication provider responsible for message delivery.

Why Twilio Integration Is Used

Twilio integration helps institutions:

• Centralize communication
• Automate notifications
• Improve parent and student engagement
• Deliver time-sensitive alerts
• Simplify communication management

Twilio supports both:

• SMS channels
• WhatsApp channels

through separate verified sender configurations.

Accessing Twilio Configuration Settings

To configure Twilio:

Settings > School Settings > Default Communication Settings

Administrators can configure Twilio credentials separately under:

• SMS tab
• WhatsApp tab

Twilio Credentials Required

To connect Twilio with openSIS, administrators typically require:

• Account SID
• Auth Token
• Verified sender number
• Test number

These credentials are provided through the Twilio account dashboard.

Account SID

The Account SID is the primary account identifier assigned by Twilio.

This value helps openSIS identify and authenticate the connected Twilio account.

Auth Token

The Auth Token is the secure authentication key associated with the Twilio account.

This token authorizes communication requests sent from openSIS.

The Auth Token should be:

• Stored securely
• Accessible only to authorized administrators

Sender Numbers

Twilio sender numbers must typically be:

• Purchased
• Registered
• Verified

through the Twilio platform.

Different sender numbers may be configured for:

• SMS communication
• WhatsApp communication

depending on institutional requirements.

WhatsApp Sender Verification

For WhatsApp communication, Twilio usually requires:

• WhatsApp sender approval
• Business verification
• Verified sender configuration

Institutions should complete all required provider-side verification processes before enabling WhatsApp communication in production.

Test Number Usage

The Test Number field helps administrators validate communication setup before activating live workflows.

Testing helps verify:

• Credential accuracy
• Gateway connectivity
• Sender number functionality
• Message delivery success

Typical Communication Workflows

Once configured, Twilio may be used in openSIS for:

• Attendance notifications
• Emergency communication
• Parent alerts
• Student reminders
• Administrative messaging
• Event announcements

Common Configuration Issues

Communication may fail if:

• Credentials are incorrect
• Sender numbers are unverified
• Twilio account permissions are restricted
• Messaging services are not activated
• WhatsApp approval is incomplete

Administrators should review provider-side configuration carefully when troubleshooting communication failures.

Security Recommendations

To maintain communication security:

• Restrict access to Twilio credentials
• Rotate credentials periodically when required
• Avoid sharing Auth Tokens publicly
• Use verified sender numbers only

Best Practices

• Test communication before production deployment.
• Use separate test numbers where possible.
• Review Twilio messaging policies regularly.
• Maintain verified sender configurations.
• Monitor communication delivery periodically.
