API development and integrations that dock anywhere
Data silos cost time every single day: records maintained twice, reports stitched together by hand. QubeLogix builds interfaces and integrations on open standards so your systems talk to each other, from shop to ERP to AI assistant.
What you get
Custom REST APIs
Cleanly designed, documented interfaces including an OpenAPI specification, so any system and any vendor can dock on.
System integrations
HubSpot, shops, ERP or accounting: bidirectional sync instead of double data entry, with proper error handling.
Webhooks and real-time events
Your systems react to each other instantly instead of waiting for the nightly import: order in, invoice out.
MCP servers for AI agents
Via the Model Context Protocol your systems become usable by AI assistants: the standard AI agents use to access tools in 2026.
Modular, not monolithic
We build with the standards your IT already speaks: REST with an OpenAPI spec, webhooks, OAuth2 and OpenID Connect for security, PostgreSQL and S3-compatible storage for data, Docker for operations. No proprietary formats, no black box.
Modular means concretely: start with one connection and extend when you need to. Every function is reachable via the API, and every part can be swapped without breaking the rest, ours included.
And if your tool is not on our list: anything with an API can be connected.
Questions about API & Integrations
Questions about API & IntegrationsCan you connect our specific system?
Very likely yes. Anything with an API, a database or a file export can be connected. Where no official interface exists, we check during the assessment which route is stable and maintainable.
What is MCP and why does it matter?
The Model Context Protocol is the open standard through which AI assistants like Claude or ChatGPT access external systems. An MCP server makes your data and functions usable by such assistants, in a controlled way with clear permissions.
How do you secure the interfaces?
With the established standards: OAuth2 and OpenID Connect for authentication, role-based permissions, encrypted connections, rate limits and audit logs. On request with single sign-on through your existing identity provider such as Microsoft Entra ID.
