API, data and business integrations without fragile plumbing
Many business problems come from tools that do not talk to each other: manual data copies, CSV files everywhere, incomplete CRM, payments not connected, unclear reporting.
Cantem builds the integration layer that makes these systems operable: APIs, webhooks, synchronizations, lightweight pipelines, clean databases and control interfaces.
What we build
Business APIs
Clean endpoints, clear contracts, authentication, permissions, logs and documentation.
Third-party integrations
CRM, Notion, Google Workspace, Stripe, Apollo, HubSpot, internal tools, data providers and business platforms.
Data synchronization
Imports, exports, webhooks, batch processing, source reconciliation, deduplication and history.
Dashboards and controls
Interfaces to monitor flows, replay errors, validate data and understand status.
Our approach
1. Identify the source of truth
We clarify which data is authoritative and which tools should consume it.
2. Define contracts
Formats, errors, authentication, sync rhythm, API limits, retries and logs.
3. Build with guardrails
No invisible scripts impossible to resume: monitoring, retries, alerts, tests and documentation.
4. Make the system operable
Teams should understand what passes, what blocks and what to do without opening the code.
