Integration Architecture

Executive Summary

Integration Architecture defines how Algosure connects to external systems through governed integration boundaries. The Integration Gateway mediates external interactions while Algosure Domains own interpreted and accepted platform facts.

Why This Exists

Algosure depends on government authorities, productivity systems, payment providers, funding partners, marketplace providers, and future country-specific integrations. These integrations must not leak external complexity into Domain modules or transfer source ownership away from the correct authority.

Owner

The owner is the Chief Product Officer and Enterprise Architect.

Business Value

Integration architecture protects tenant data, preserves source ownership, supports reliable external workflows, and creates a governed path for expanding Algosure across providers and countries.

Integration Groups

Group	Systems
Government and compliance	SARS, CIPC, CSD, CIDB, COIDA, B-BBEE agencies, and future country-specific authorities.
Productivity and collaboration	Gmail, Outlook, Google Drive, OneDrive, DocuSign, and WhatsApp.
Marketplace and funding	Funding partners and marketplace providers.
Payments	Payment providers.
Future expansion	Future government, country-specific, regional, and sector-specific integrations.

Ownership Rules

Rule	Requirement
External systems remain authoritative	External providers own their own records, decisions, delivery, availability, policies, and terms.
Domains own interpreted facts	Algosure Domains own accepted platform facts, workflow state, decisions, and events derived from external information.
Integration Gateway does not own business facts	The gateway mediates connectivity, security, retries, translation, and audit; it does not become a Domain.
Tenant context is mandatory	Every integration request, response, webhook, credential, error, and audit record must be tenant-scoped.
Events are preferred for meaningful changes	External observations that affect Algosure should produce domain-owned events where appropriate.
Contracts precede implementation	Provider contracts, errors, retries, rate limits, data handling, and ownership must be designed before endpoint specs.

Non-Implementation Boundary

This document does not define provider API specs, endpoint paths, OAuth scopes, webhook routes, message broker products, mapping schemas, or infrastructure configuration.
