Integrations

Purpose

This page documents external and internal integrations used by the Maqsafy platform.

The purpose is to define integration boundaries, data flow, security rules, ownership, failure handling, and operational requirements.

Integration Scope

Integrations may include:

• SMS provider
• Email provider
• Payment gateway
• Object storage
• Webhooks
• Reporting/export services
• School roster import or sync
• External POS or payment components
• NFC-related components outside dashboard scope

Important Boundary

The dashboard does not scan or read NFC credentials.

Dashboards may display and manage credential identifiers, credential inventory, assignment status, and delivery status based on user permissions.

NFC scanning, tap-to-pay, issuance, or payment capture must be documented under the relevant mobile app, POS, or external payment component.
