Integration Challenges We Solve With Custom Connectors
Explore the common integration challenges businesses face and how our connector development services help solve them.
Prebuilt Connectors Don't Fit
Your system is proprietary, niche, or internal with no marketplace connector available. Our team builds connectors from scratch to your exact specifications.
Legacy Systems Block Integration
AS/400, COBOL, and SOAP systems cannot connect directly to modern platforms. We build connectors that bridge both worlds without touching your existing infrastructure.
Non-Standard APIs Break Logic
Many enterprise APIs use custom authentication, irregular endpoints, and unpredictable behavior. Our team handles every edge case so your integration runs without failure.
Complex Data Fails Mapping
Nested, multi-format, or high-volume data structures break standard transformation logic. We build connector-level mapping that handles your exact data reliably at scale.
Compliance Demands Full Traceability
Regulated industries require every data movement to be logged, encrypted, and auditable. Our connectors are built with compliance and traceability controls at every layer.
Connectors Collapse Under Load
Standard connectors expose their limits fast when traffic spikes hit production systems. We engineer for high-throughput reliability, so your integrations hold up consistently.

Our Recent Success Stories
Here are some of our recent case studies that show how we have helped businesses solve complex integration challenges across industries.
Marketplace Connector Suite for a B2B SaaS Platform
Industry: SaaS
Core Technology: Node.js | TypeScript | OpenAPI 3.0 | OAuth 2.0 | GitHub Actions | Postman
A SaaS company wanted to launch an integration marketplace but had only built 4 connectors internally, which was not enough to attract users. We developed 23 ready to use connectors for Salesforce, HubSpot, Pipedrive, Slack, Jira, and other platforms. Each connector included OpenAPI specs, OAuth login, retry handling, and flexible SDK support. As a result, their marketplace usage increased by 38% within one quarter.

Mainframe-to-MuleSoft Connector for a Regional Bank
Industry: Banking & Finance
Core Technology: MuleSoft Anypoint | AS/400 | DataWeave | JMS | Splunk | SOX Audit
The client was a regional bank that required integration of AS/400 systems with MuleSoft, without any modification to its existing system configuration. Our team was able to develop an integration solution, which took care of copy books, files, and logs through Splunk. This resulted in the client’s settlement process time being reduced from 6 to 35 minutes.

HIPAA-Compliant FHIR Connector for a Healthcare Network
Industry: Healthcare
Core Technology: Apache Kafka | FHIR R4 | HL7 v2.5 | Azure API Management | HashiCorp Vault
A hospital network needed real-time data sharing between multiple EHR systems while following strict HIPAA rules. Using our custom connector services, we built a Kafka-based solution with FHIR conversion, PHI protection, audit logs, and failed message handling. As a result, their system now handles 2.4 million events daily with zero compliance issues over the last 18 months.

Our Connector Development Process
We follow a structured process designed for systems that must stay stable in production and handle complex integration dependencies reliably.
Discovery & System Analysis
First, we analyze systems, APIs, authentication flows, and failure points to create a clear technical specification before any connector development begins.
Architecture & Connector Design
Then we define data models, transformations, retries, error handling, ensuring design approval before starting connector development work.
Development & Testing
We build connectors in iterations with unit, integration, and contract testing to ensure production-ready behavior throughout development cycles.
Deployment & Maintenance
Finally, we deploy connectors with documentation, runbooks, and monitoring support, followed by ongoing maintenance for updates, fixes, and platform changes.

Frequently Asked Questions
Still have questions? Let's talkThe vast majority of connectors are somewhere between 2 and 6 weeks away from completion. A basic REST connector will take 2 weeks to complete. If you happen to be working with mainframe integration or with EDI, expect an additional 4 to 6 weeks for the connector. Passing the certification process of the marketplace takes up to 1 week.
The code, installation instructions, documentation, run books, and test cases are provided to you. Authorization and retry, as well as error handling logic, are built into the software. Before we release the software, we conduct a knowledge transfer session for you, and stay for 30 days past launch.
You own absolutely everything. The source code, the repository, the documentation, all yours to use as you please. We do not hold any licensing rights, nor do we place any limitations on your use of our products.
Yes, and we build with that in mind from the start. Tenant-scoped auth, isolated config, per-tenant rate limiting, so the same codebase works cleanly across every tenant and holds up to marketplace listing requirements.
We do. APIs update, platforms change, auth schemes shift. We offer SLA-backed maintenance covering API updates, compatibility fixes, bugs, and new features. Most clients move to a monthly retainer once things are live, which makes the most sense for ongoing work.
Honestly, that's most of what we do. AS/400, COBOL mainframes, internal APIs with zero documentation, EDI X12, custom SOAP, proprietary protocols, we've handled all of it. We don't need a full spec to get started. A sample payload or a working endpoint is usually enough to kick off discovery.
