Custom connections when native integrations fall short
API & Systems Integration
Connect software that does not communicate through reliable APIs, webhooks, middleware, scheduled synchronization, and custom integration logic.
Optimion handles the mapping, authentication, duplicate behavior, retries, logging, and operational ownership required to make integrations dependable after the happy-path demo.
- REST APIs
- OAuth
- Webhooks
- Scheduled sync
- Power Automate
- Make
- Zapier
- n8n
- Custom connectors
Operational needs
Integration work we handle
The work starts with the actual handoff, exception, or decision that is slowing the team down—not with a predetermined platform.
- CRM, ERP, accounting, and commerce synchronization
- Systems with APIs but no useful native connector
- Event-driven updates through webhooks
- Scheduled imports, exports, and reconciliations
- OAuth and token lifecycle implementation
- Field transformation and identifier mapping
- Duplicate detection and idempotent updates
- Retries, logging, alerts, and exception queues
Implementation approach
Built around the system of record and the people using it
- 1
Map the process
Document source and destination objects, identifiers, and field ownership
- 2
Design the system
Choose event-driven, scheduled, or hybrid synchronization
- 3
Build and validate
Implement authentication without exposing credentials to the client
- 4
Launch with ownership
Make writes idempotent and failures observable
- 5
Monitor and improve
Test rate limits, retries, partial failures, and reconciliation
Systems we work with
Experience integrating with your operating stack

Good fit
Who this service is for
- Businesses whose systems do not have a suitable native connector
- Teams moving information through CSV files or copy-and-paste
- Organizations needing custom Business Central, CRM, or commerce connections
- Workflows that require predictable error handling and auditability
Frequently asked questions
Straight answers before we talk
What if our software does not have a native integration?
We inspect its API, webhook, export, database, and authentication options. Depending on the system, we can build a custom connector, use scheduled synchronization, or create a controlled import/export workflow with logging and error handling.
Do you work with webhooks and OAuth?
Yes. Integrations can use webhook-driven events, OAuth authorization flows, token refresh, signed requests, and scheduled polling depending on the platform's supported model.
How do you prevent duplicate records?
We define stable external identifiers, use idempotent create-or-update patterns, persist mapping keys when needed, and test retry behavior so the same event does not create repeated records.
Can you use Power Automate, Make, Zapier, or n8n?
Yes. The choice depends on the systems, required control, expected volume, internal ownership, and error-handling needs. Custom code is used when a workflow tool cannot meet those requirements cleanly.
