API & systems integration · Burlington, Ontario
Application Integration & API Services for Burlington Businesses
Business systems that do not talk to each other create duplicate data entry, reconciliation work and error. We design, build and maintain the integrations and APIs that connect your platforms, following OWASP secure development guidance throughout.
What this covers
- Point-to-point and middleware-based integration design
- REST and webhook-based API development
- Secure authentication and credential handling
- Data mapping and transformation between systems
- Monitoring for silent integration failures
01Why integration is treated as its own discipline
Integrations fail quietly, not loudly
A broken integration rarely throws an error a user sees. It usually just stops updating, and the gap is discovered weeks later during reconciliation.
Connecting a CRM to an accounting platform, an ERP to an e-commerce storefront, or an internal database to a reporting tool involves more than moving data from one place to another. Field mapping has to survive both systems' independent update cycles, authentication needs rotating credentials rather than embedded secrets, and error handling needs to surface failures rather than swallow them. OWASP secure coding guidance on input validation, authentication and secrets management applies directly here, even though integration work is not usually described as application development.
Integration architecture is chosen deliberately rather than defaulted to whatever the first vendor's connector supports: direct point-to-point calls for simple, low-volume needs; a middleware or iPaaS layer where multiple systems need to exchange data and a single point of transformation and logging is worth the added component. ITIL 4 service design principles apply to the decision — the simplest architecture that meets the requirement, not the most elaborate one that could theoretically handle future needs.
For Burlington organizations running a mix of cloud SaaS and on-premises platforms, integration is frequently the difference between staff re-keying data across three systems and a business that reports accurately in near real time.

- Legacy system integration via file or database bridges
- Ongoing monitoring and maintenance of live integrations
03Secure development practice
Security controls applied to every integration
Integrations move data between systems, which makes them a natural target for review under ISO/IEC 27001 secure development and supplier controls.
- Credentials stored in a secrets manager, never in code
- Least-privilege API scopes and access tokens
- Input validation on every data field received
- TLS enforced on all data in transit
- Rate limiting and abuse protection where exposed publicly
- Logging that avoids capturing sensitive personal data
- Data residency reviewed against PIPEDA obligations
- Failure states designed to fail closed, not silently pass bad data
- Regular review of third-party API dependency changes
- Version control and rollback for integration logic
- Test environments separate from production data
- Documented data flow diagrams for audit and review
FAQCommon questions
Questions Burlington organizations ask
Can you integrate systems from different vendors that were never designed to work together?
In most cases, yes. Where both systems expose an API or support file-based exchange, an integration can be built even without a native connector. We assess feasibility and data quality before committing to an approach.
How do you handle personal or customer data moving between systems?
Data flows are mapped explicitly, and where personal information is involved, storage location and processing are reviewed against PIPEDA obligations. Sensitive fields are excluded from logs and secured in transit and at rest.
What happens if an integration breaks?
Integrations are built with monitoring and alerting so a failure is flagged rather than discovered during month-end reconciliation. Response follows the same incident process used across your other supported systems.
Do we need to replace our current software to integrate it?
Rarely. Most integration work connects existing platforms as they are, using their available APIs or export capabilities. Replacement is only recommended where a platform genuinely lacks any integration path.
