Move Forward with the Right API Integration Services
Your systems already hold the data. The right integration is what turns it into hours saved, records your teams can trust, and decisions made on current numbers
Custom API Integration
When no connector exists for your stack, we build the integration from scratch: endpoints, data mapping, transformation rules, and error handling.
- Built around your data model
- Retries and edge cases handled
- Documented and version-controlled

Third-Party API Integration
Connect the services you already pay for: payments, shipping, mapping, and analytics. We handle authentication, rate limits, and vendor version changes.
- Stripe, Twilio, Google, HubSpot
- OAuth 2.0 and API key auth
- Monitored for deprecations

REST & SOAP API Integration
REST for modern applications, SOAP where regulated and legacy enterprise systems require it. Most projects need both, built into one architecture.
- WS-Security and WSDL contracts
- JSON and XML transformation
- GraphQL and gRPC where they fit

Payment API Integration
Payment flows that handle transactions, refunds, subscription billing, and reconciliation, with PCI DSS requirements accounted for from the start.
- Stripe, PayPal, Adyen
- Webhooks for real-time events
- Disputes and recurring billing

CRM & ERP Integration
Keep customer, order, and financial records in sync across Odoo, Microsoft Dynamics 365, Salesforce, HubSpot, SAP, and NetSuite.
- Duplicate detection built-in
- Two-way or event-driven sync
- Field-level mapping and validation

Cloud API Integration
Connect applications to AWS and Azure services and build event-driven pipelines that scale with volume instead of breaking at peak load.
- Multi-cloud AWS and Azure
- Serverless and queue-based flows
- Autoscaling with cost control

Legacy System Integration
Wrap old systems in modern APIs instead of replacing them. Middleware, adapters, and transformation layers connect systems without their own APIs.
- No rip-and-replace required
- Custom middleware and adapters
- Phased cutover with rollback

API Development & Documentation
For when you need to expose your own API, not just consume someone else's: design, build, OpenAPI specs, and docs your partners can work from.
- OpenAPI and Swagger specs
- Versioning and deprecation policy
- Internal and public APIs

API Testing & Security
Contract tests, load runs at peak volume, and penetration testing, plus the security layer: gateway, OAuth 2.0, rate limiting, and audit logging.
- API gateway and rate limiting
- Penetration testing
- HIPAA and GDPR ready

API Maintenance & Support
Integrations break when vendors change their APIs. We monitor for failed syncs, run version migrations, and fix breaks before your team notices.
- Alerting on failed syncs
- Version migrations handled
- SLA-backed response times

Signs You Need API Integration
Integration becomes urgent at the point where manual workarounds cost more in hours than building the connection ever would.
Manual Data Entry
- Staff retype orders across apps
- Hours lost to copy-paste weekly
- Typos trigger costly rework
Cash Flow Delays
- Invoices wait on manual approval
- Payments sit unmatched for days
- Month-end close takes a week
Data Access Risks
- Files shared via email and USB
- No audit trail for data changes
- Passwords stored in shared docs
Get Every System You Already Run Working from the Same Data
Whatever mix of platforms you run, we connect it into one flow of data, with no re-keying and no conflicting records.
ERP Systems
SAP, Oracle, Microsoft Dynamics, and NetSuite connected to the rest of the stack: real-time inventory flowing to e-commerce, financial data syncing to reporting tools.
CRM Platforms
Salesforce, HubSpot, Zoho, Pipedrive, and Dynamics CRM. Customer data, deal pipelines, and communication history stay synchronized across sales, marketing, and support.
E-commerce Platforms
Shopify, Magento, WooCommerce, and BigCommerce synced with backend systems. Orders, inventory, customer records, and product catalogs stay current, which is where the ROI shows up.
Payment Systems
Stripe, PayPal, Square, Braintree, and custom gateways. Payment flows handle transactions, refunds, subscription billing, and compliance while financial data stays in sync.
Healthcare Systems
HL7, FHIR, and HIPAA requirements built in from the start. EHR platforms, lab systems, pharmacy systems, and patient engagement tools connected with proper data governance.
Custom and Legacy Systems
Not every system has a modern API. Custom middleware, transformation layers, and adapter services connect proprietary databases and internal tools, regardless of their age.
What You Get from Connected Systems
One connected setup replaces manual handoffs, so your team makes decisions based on consistent data.
Keep Every Integration Secure from Build to Handover
Security and compliance requirements are built into each integration, not bolted on after launch. Certified partnerships cover the platforms your systems already run on.

The Scope of API Integration Services
Most companies already own the data they need. It's just scattered across systems that were never built to talk to each other, so someone ends up moving it by hand. An API removes that step and lets the systems exchange data directly. The services below cover the whole job: connecting what you already run, building custom APIs where none exist, securing every connection, and keeping it all working as vendors change.
Common API Architecture Patterns
Every API integration project starts with a protocol decision, and each option carries a cost as well as a benefit.
|
Protocol |
Best for |
Trade-off |
|
REST |
Modern web services and mobile apps |
Chatty for complex queries |
|
SOAP |
Regulated enterprise software applications |
Heavier payloads, slower to change |
|
GraphQL |
Precise fetching from several data sources |
Caching and rate limiting get harder |
|
gRPC |
High-throughput traffic between different systems |
Limited browser support |
|
Webhooks |
Real-time events instead of polling |
Delivery needs retries and idempotency |
Beneath the protocol layer runs the API infrastructure: a gateway for routing and rate limiting, OAuth 2.0 and API keys for authentication, middleware that reconciles data formats, and event-driven architecture for flows that cannot wait on a nightly batch. API management, automated API testing, and continuous monitoring separate effective API integration services from work that needs rebuilding later.
API Consulting, Strategy, and the Integration Process
Most projects begin with API consulting before any code is written. The integration process maps which business processes stall, which data sources disagree, and which private APIs or third-party APIs are in play. That produces an API strategy: what to connect first, which process automation to prioritize, and what to leave alone. Glorium Technologies runs this as scoped discovery, so development services begin against a plan.
Integration Platform or Custom API Development
Leading API integration platforms such as MuleSoft, Boomi, Workato, IBM API Connect, and Make or Zapier cover a lot of ground. When both systems have connectors and the logic is mostly mapping and routing, an integration platform is the faster route to workflow automation. Custom API development earns its cost in four situations:
- No connector exists for a proprietary system
- Per-transaction pricing breaks at volume
- Business logic lives between the systems
- Data residency or compliance rules the platform out
As an API development company, Glorium Technologies builds scalable and secure APIs for those cases. Most API integration solutions end up hybrid: platform-based data exchange for straightforward syncs, custom API solutions, and scalable APIs for the connections carrying revenue.
Glorium Technologies, Your Go-to for API Integration Services
Who builds the connection matters as much as the protocol running through it. The right partner learns how your teams already work and gives the project a clear path from discovery to production. The distance between companies earning a return on their APIs and those treating them as plumbing keeps widening. Around 82 percent of organizations have adopted some level of API-first development, yet only a quarter have gone all the way, and that smaller group pulls a far larger share of revenue through its API programs. What separates them is rarely tooling. They redesign business processes around API interactions instead of bolting a connector onto a workflow nobody changed. A seasoned API development company changes that equation. Glorium Technologies is an AWS partner, a Microsoft partner, a certified Odoo partner, and a Stripe-verified partner, spanning cloud infrastructure, enterprise resource planning, customer relationship management, and payments. In-house teams have built integrations since 2010, including HL7 and FHIR API integrations that connected an AI diagnostics platform to Epic and Cerner. Bring your requirements, and the integration gets built around your business goals, tested before launch, and monitored long after it.
