API Integration Services That Connect Your Systems Without Re-Entering Data
Hexagon connects CRM, ERP, websites, mobile applications, payments, cloud platforms, and legacy systems through secure integrations designed around data ownership, identity rules, validation, monitoring, and business workflow. For CRM builds, integrations and migrations, see our CRM development services. Hexagon IT Solutions is a U.S. API integration company, led from Draper, Utah since 2007, with 300+ projects delivered.
Most Integration Problems Are Data-Ownership and Reliability Problems—Not Just API Problems
Connecting a CRM specifically? See CRM integration services for QuickBooks, ERP and marketing tools.
An API connection can technically work while the business still experiences duplicate customers, conflicting record IDs, delayed updates, silent failures, incorrect field mappings, and reports that cannot be trusted.
Hexagon defines which system owns each record, how identities are matched, when data moves, how it is validated, what happens when a request fails, and who is notified before the integration is built.
From Disconnected Work to One Accountable Process
Before
- Export files
- Copy and paste
- Duplicate records
- Conflicting IDs
- Silent failures
- Manual reconciliation
After
- System-of-record rules
- Identity matching
- Validated API flow
- Retry and exception handling
- Monitoring
- Trusted reporting
The objective is not to add more software. It is to create clear ownership, reliable data movement, consistent execution, and reporting the business can trust.
Which Integration Approach Fits the Requirement?
The best integration may use a native connector, direct API, middleware, event-driven workflow, batch synchronization, or a custom API.
A supported native connector meets the required data, timing, and reliability needs.
Typical DeliverableConnector setup, field mapping, permissions, testing, monitoring, and documentation.
Two systems have suitable APIs and a direct governed connection is manageable.
Typical DeliverableAuthentication, endpoints, mappings, transformations, validation, retries, and logging.
Several systems or workflows require orchestration, routing, and centralized monitoring.
Typical DeliverableIntegration layer, queues, transformations, workflow rules, observability, and support model.
A legacy or custom platform does not expose the capabilities required for integration.
Typical DeliverableAPI design, security, business rules, documentation, versioning, testing, and lifecycle support.

Monitoring, Support & Integration Modernization
Monitor health, surface failures, manage retries, update authentication and versions, improve performance, and support changing systems.
API integration services for U.S. companies
Most integration work we see falls into three groups. Each one starts with a free 30-minute review and a written integration spec.
CRM and ERP integration
Connect your CRM to ERP, accounting and billing so customers, quotes, orders and invoices stay consistent across systems. See our CRM integration services and ERP services.
Legacy system integration services
Keep the older system that still runs core operations and connect it to modern apps through APIs, database connectors or scheduled file exchange, without a risky full replacement.
Payment gateway integration services
Connect payment gateways to your website, CRM, ERP and accounting with reconciliation, refunds and failure handling. See payment gateway integration.

From Integration Discovery to Monitored Production Data Flow
Integration delivery should resolve ownership, identity, mapping, timing, security, failure handling, testing, monitoring, and support before production traffic is enabled.
Systems & Workflow Discovery
Identify systems, business events, data owners, users, dependencies, and desired outcomes.
Data Mapping & Integration Design
Define records, identities, fields, transformations, timing, authentication, and the integration pattern.
Error, Security & Monitoring Design
Define validation, retries, duplicate prevention, exception handling, alerts, logs, and access controls.
Build & Configure
Develop APIs, connectors, middleware flows, queues, transformations, and administration tools.
Test & Reconcile
Validate normal and failure scenarios, data counts, relationships, timing, performance, and business outcomes.
Launch & Operate
Enable production flow, monitor health, resolve exceptions, maintain versions, and improve performance.
An Integration Layer Connecting Systems Without Losing Control of the Data
The integration layer should govern how information is identified, transformed, validated, delivered, monitored, and recovered when a system or request fails.
Source Systems
Integration Layer
Target Systems
Observability & Control
Built for Secure Change, Not Just Launch Day
A successful technology project must protect business information, move data safely, clarify ownership, and support the people who will use the solution every day.
Security by Design
Use secure authentication, role-based access, encrypted data transmission, audit logging, and least-privilege permissions based on the sensitivity of the data and hosting environment. Final controls are confirmed during discovery and solution design.
Migration with Validation
Plan migration around data assessment, field mapping, cleanup, test migrations, record-count validation, attachment and history handling, cutover, and post-migration checks.
Clear Ownership & Handover
Your business data remains yours. Source-code ownership, licensing, hosting, repository access, documentation, credentials, and handover responsibilities are defined in the proposal and project agreement before development begins.
Adoption & Ongoing Support
Design around real user roles, provide training and documentation, validate with users before launch, monitor performance after launch, and improve the solution as business requirements change.
How API Integration Engagements Are Scoped
Integration projects are scoped around systems, APIs, records, identities, data volume, synchronization timing, transformations, authentication, business rules, failure handling, monitoring, testing, and support.
Connector or Direct API Integration
Best for a defined connection between two systems with clear data ownership and manageable workflow requirements.
Multi-System Integration
Best for several platforms requiring transformations, orchestration, queues, centralized monitoring, or shared identity rules.
Custom API or Integration Platform
Best for legacy systems, digital products, partner access, complex workflows, or reusable integration capabilities.
Discuss your project →Hiring an API integration company: what to expect
Any API integration company you hire should agree the data rules before it writes code, and should still be accountable after launch. With Hexagon you get:
A written integration spec
Systems, endpoints, field mapping, data ownership, sync direction and frequency, and error handling, agreed before the build starts.
Monitoring after go-live
Logging, retries and alerts, so failures and duplicates are caught early instead of showing up in reports or customer records.
Documentation you own
Clear documentation and source code your in-house IT team can maintain, with ongoing support available if you want it.

Anonymized projects from our portfolio, plus the services that usually sit next to an integration project.
Frequently asked questions and answers
What is the difference between API integration and API development?
API integration connects existing applications so they can exchange information and trigger workflows. API development creates a new interface that allows a system or product to expose approved data and capabilities to other applications.
Which business systems can Hexagon integrate?
Hexagon can integrate CRM, ERP, accounting, websites, mobile applications, payments, eCommerce, portals, marketing, support, document storage, databases, cloud services, analytics, and other business platforms that provide suitable access.
Can legacy systems be integrated with modern applications?
Yes. A legacy system may be integrated through an existing API, database access, secure file exchange, middleware, queues, robotic automation, or a custom API. The approach depends on access, security, data quality, reliability, and supportability.
Should an integration run in real time or on a schedule?
Real-time integration is appropriate when the next business action depends on immediate information. Scheduled or batch synchronization may be more reliable and economical for large volumes, reporting, or processes that do not require instant updates.
How do you secure API integrations?
Integration security should address authentication, authorization, encryption, secrets, least-privilege access, input validation, rate limits, logging, data sensitivity, network controls, and credential rotation. Final controls depend on the connected systems and hosting environment.
How are API failures, duplicates, and synchronization errors handled?
Reliable integrations should include validation, idempotency or duplicate prevention, retries, exception queues, logs, alerts, reconciliation, ownership, and support procedures. Hexagon defines these controls during integration design.
What should we look for in an API integration company?
A written integration spec before any build, clear rules for which system owns each piece of data, monitoring and alerts after go-live, documentation your team can use, and case studies for similar systems. Hexagon has delivered 300+ projects since 2007 and is led from Draper, Utah.
Do you offer legacy system integration services?
Yes. We connect older systems to modern CRM, ERP and web applications through APIs, database connectors or scheduled file exchange, so you can keep what works while adding new tools.
Do you provide payment gateway integration services?
Yes. We integrate payment gateways with websites, portals, CRM, ERP and accounting, including reconciliation, refunds and handling of failed payments.
Can you connect our CRM and ERP?
Yes. CRM and ERP integration is one of our most common projects: accounts, quotes, orders, invoices and inventory synced in one or both directions with agreed ownership rules.
