API development & integration

Make your systems work like one operation.

We design and support secure APIs, data connections, and automated handoffs between CRM, ERP, accounting, ecommerce, databases, cloud services, and custom applications.

Integration without fragility

The difficult part is dependable data movement.

An API can connect two endpoints quickly. A production integration must also decide which system owns each field, how records are matched, what happens when a vendor is unavailable, which changes are allowed, and how staff can see and correct exceptions. Ignoring those details creates silent data drift and expensive manual cleanup.

Naper Solutions approaches integration as an operating system between applications. We document the source of truth, business events, transformation rules, security boundaries, expected volume, recovery behavior, and support process before the connection becomes critical.

We work with modern REST and webhook interfaces as well as older databases, flat-file exchanges, scheduled processes, and applications that were never designed to integrate. The result can be a focused point-to-point connection or a reusable service layer that supports several workflows.

Integration outcomes

Faster flow with fewer blind spots.

Good integration removes delay and duplication while preserving control over important business decisions.

Automatic handoffs

Move approved customers, orders, invoices, inventory, documents, and status changes without repeated manual entry.

Controlled access

Use appropriate credentials, permissions, encryption, input validation, and audit records for each connection.

Visible exceptions

Capture failures, retries, unmatched records, and business-rule conflicts so the right person can resolve them.

Supportable operations

Monitor throughput and errors, document dependencies, and plan for vendor changes before they become emergencies.

Scope

The interface, workflow, and operational controls.

We can build a new API, consume an external one, or create the integration layer between a mix of modern and legacy systems.

API engineering

Secure interfaces for applications, partners, mobile experiences, and internal services, designed around clear contracts and ownership.

  • REST API design and implementation
  • OAuth, API keys, SSO, roles, and permissions
  • Versioning, validation, documentation, and testing
  • Rate limits, logging, monitoring, and performance

Business system integration

End-to-end connections that include transformation, matching, orchestration, and practical failure recovery.

  • CRM, ERP, accounting, and ecommerce connections
  • Webhooks, queues, scheduled sync, and event processing
  • Database, file, EDI, and legacy application bridges
  • Reconciliation tools and exception dashboards
How we work

Design the operating contract before the code.

A short discovery step prevents the most common integration failures: unclear ownership, incomplete rules, and no recovery plan.

STEP 01

Map

Identify systems, owners, records, events, volumes, timing, dependencies, and security boundaries.

STEP 02

Specify

Define contracts, mappings, matching rules, allowed changes, exceptions, retries, and reconciliation.

STEP 03

Build and prove

Implement against test environments and representative data, including rate limits and failure scenarios.

STEP 04

Operate

Deploy with monitoring, credentials management, documentation, alerting, and an ongoing support path.

1997

Built for continuity, not a handoff.

Naper Solutions has solved business technology problems since 1997. The same senior team can carry an engagement from assessment through implementation, deployment, and ongoing support.

Common questions

API and integration questions.

Can you integrate software that does not have an API?

Often, yes. Depending on the system, we may use supported database access, scheduled file exchange, vendor import tools, email processing, browser automation, or a small adapter service. We first evaluate supportability, security, and vendor restrictions.

Do you build both APIs and the applications that use them?

Yes. We can create the service interface, the surrounding business workflow, an administrative dashboard, and the custom application or portal that consumes it. We can also work with an existing internal or vendor development team.

How do you prevent duplicate or missing records?

We design stable identifiers, idempotent operations, matching rules, checkpoints, retries, and reconciliation reporting. The exact controls depend on the systems and the business consequence of a missed or duplicated transaction.

What happens when a connected vendor changes its API?

Versioning, monitoring, tests, and clear dependency documentation make changes easier to detect and manage. With an ongoing support arrangement, we can review vendor notices, update the integration, and validate the affected workflows.

Can an integration run in real time?

Yes, when the source systems and business process support it. Webhooks, event queues, and APIs can provide near-real-time flow. Scheduled synchronization may be safer or more economical when vendor limits, volume, or reconciliation requirements favor batches.
