Integration Services

Integrations that make systems actually talk.

APIs, event streams, and data pipelines — the connective tissue of enterprise IT. From ServiceNow ↔ Service Manager migrations to mainframe ↔ cloud data flows.

What we do

The plumbing that keeps enterprise systems useful.

Modern IT is a mesh of systems that need to share data — cleanly, reliably, in real time or batch. Getting that plumbing right is what separates high-performing IT organizations from perpetually-firefighting ones.

VanPaulTek designs and delivers integrations across the boundaries most other teams find hardest: ServiceNow ↔ Service Manager, mainframe ↔ cloud, monolithic legacy apps ↔ modern microservices.

Every integration we deliver ships with contracts, tests, monitoring, and documentation. It's boring, and that's the point.

Integration patterns

Types of integration we deliver.

The right pattern for your data-sharing shape.

REST

REST APIs

HTTP-based APIs with OpenAPI contracts, versioning, rate limits, and auth.

GQL

GraphQL APIs

Flexible client-driven APIs with schema-first design.

Event

Event Streaming

Kafka, Kinesis, SNS/SQS — decoupled, scalable, event-driven.

ETL

Batch ETL / ELT

Reliable data pipelines: extract, transform, load — Airflow, dbt, Snowflake.

iPaaS

iPaaS Connectors

MuleSoft, Boomi, Workato — prebuilt integration platforms.

ID

Identity / SSO

SAML, OIDC, SCIM — enterprise auth done right.

LGCY

Legacy Bridges

APIs over mainframe transactions, VSAM data, SOAP → REST.

Web

Webhooks

Reliable webhook delivery with retries, dead-letter, and observability.

What we deliver

Design, build, run.

API Design & Contracts

OpenAPI schemas up front. Consumers can build in parallel with providers.

ServiceNow Integrations

IntegrationHub spokes, custom REST, ServiceNow ↔ Service Manager sync.

Event-Driven Architecture

Kafka, Kinesis, and pub/sub for real-time decoupled systems.

Batch Data Pipelines

ETL/ELT with Airflow, dbt, Fivetran, custom pipelines when needed.

Identity & Access

SSO, MFA, SCIM provisioning across enterprise identity.

Legacy Modernization

API layers over mainframe, iSeries, legacy databases.

Enterprise Bus / iPaaS

MuleSoft, Boomi, Workato — when a platform makes sense.

Observability

Every integration monitored: latency, error rate, data quality, freshness.

Managed Ops

24×7 on-call for critical integration pipelines.

How we deliver

Contract, build, run.

01

Discover

Data model on both sides, volumes, latency requirements, failure modes.

02

Contract

API schema or event contract, agreed with consumers up front.

03

Build

Implementation with tests, contract validation, error handling.

04

Deploy

Staged rollout with monitoring and rollback.

05

Monitor

Latency, error, data quality, and freshness dashboards.

06

Evolve

Versioning strategy, deprecation, ongoing improvement.

What we're typically hired to do.

🔄

ServiceNow ↔ Service Manager

Bi-directional sync during a phased migration between platforms.

🏛️

Mainframe ↔ Cloud

APIs over CICS/DB2 so modern apps can use the system of record.

📊

Data Warehouse Pipelines

ELT into Snowflake/BigQuery from every operational system.

🔐

Enterprise SSO Rollout

SAML/OIDC across the app portfolio with SCIM provisioning.

📡

Event Backbone

Kafka event streams for decoupled cross-system flow.

🔌

Legacy API Layer

REST facade over SOAP or proprietary legacy APIs.

FAQ

Questions we hear often.

Which iPaaS do you recommend? +

It depends on your existing landscape, team skills, and volumes. We're not resellers — happy to recommend against a platform when it doesn't fit.

Do you build custom integrations or use platforms? +

Both. Platforms accelerate common patterns; custom code makes sense when the pattern is unique or performance-critical.

Can you handle high-volume event streams? +

Yes. Multi-hundred-thousand-events-per-second stacks are in our experience.

How do you handle contract versioning? +

Semantic versioning, deprecation windows, and consumer migration support built into every API.

Do you monitor integrations post-launch? +

Yes — observability is part of every delivery. Optional 24×7 managed ops for critical pipelines.

Mainframe integration — is that really possible? +

Yes. We do it regularly — via CICS Transaction Gateway, MQ, DB2 replication, and API middleware.
