System Integrations & API Development

The Challenge

Modern organisations rarely operate on a single platform. Over time, businesses accumulate a patchwork of systems -- CRMs, project management tools, email platforms, cloud services, bespoke databases -- each holding a piece of the operational puzzle. When these systems cannot communicate, data gets siloed, manual re-entry introduces errors, and teams spend hours on work that should be automated.

Integration challenges are compounded by the diversity of APIs, data formats, and authentication mechanisms involved. Some systems offer well-documented REST APIs; others provide only legacy SOAP interfaces or flat file exports. The technical work of connecting them must account for data mapping, error handling, rate limiting, and the ongoing maintenance burden as upstream APIs change without warning.

Our Approach

Digital Tactics approaches integration as an architectural discipline, not just a plumbing exercise. We begin by mapping the data flows between systems, identifying the canonical data model, and designing integration patterns that are resilient to failure and change. Whether the requirement is a one-time data migration or an ongoing bidirectional sync, we build solutions that handle edge cases, log comprehensively, and degrade gracefully when external services are unavailable.

Our integration toolkit spans PHP, Python, JavaScript, and AWS services. We build custom API clients, middleware services, and ETL pipelines tailored to each client's specific system landscape. For cloud-native integrations, we leverage AWS Lambda, SQS, and API Gateway to create scalable, serverless integration layers. For legacy systems, we build adapter patterns that translate between old and new protocols without requiring changes to the legacy codebase.

• Architecture-first approach mapping data flows and canonical models before writing integration code
• Resilient integration patterns with comprehensive error handling, logging, and graceful degradation
• Serverless integration layers on AWS for scalable, cost-effective system connectivity
• Adapter patterns bridging legacy protocols with modern APIs without modifying source systems

Projects & Clients

The JIRA PHP Client project built a comprehensive API wrapper enabling PHP applications to interact with Atlassian JIRA for project management automation. AWS Cognito Export developed tooling to extract and migrate user identity data from AWS Cognito, solving a common problem for organisations needing to move between identity providers. The XoomTalk/4PSA integration connected VoIP telephony systems with business applications, enabling automated call logging and communication workflow management.

AVT Connect built integration middleware for audiovisual technology management, connecting scheduling, asset management, and control systems into a unified operational platform. The C and M Email Migration project handled the complex task of migrating email data between platforms while preserving folder structures, metadata, and attachments. Jon Snow Video Email and Mail Trumpet developed novel email integration capabilities, embedding rich media content within email workflows. The Corporate Email Editor provided a custom email template builder integrated with existing marketing and CRM systems for consistent brand communications.

Results & Impact

• Custom API clients and middleware connecting diverse system landscapes including JIRA, AWS Cognito, and VoIP platforms
• Successful large-scale email migrations preserving data integrity across platform transitions
• Novel email integration solutions embedding rich media and video within standard email workflows
• Elimination of manual data re-entry and reduction of integration-related errors across client operations
