Overview

What Our API & Integration Services Team Delivers

Disconnected systems create duplicate work, reporting gaps, and slow customer experiences. TGT builds APIs and integrations that let your software ecosystem communicate reliably.

We design secure APIs, connect third-party tools, automate business workflows, and integrate payment gateways, CRMs, ERPs, SaaS platforms, analytics systems, and custom applications.

Our integration work focuses on stability, error handling, documentation, and monitoring, because a useful integration needs to keep working after the first successful test.

  • Connecting a product to CRM, ERP, payment, shipping, or marketing tools.
  • Building secure APIs for mobile apps, web apps, and partners.
  • Automating workflows across multiple systems.
  • Replacing manual imports, exports, and duplicate data entry.
