API & Systems Integration
Connect the tools you rely on with reliable, observable, and secure data flows.
API & Systems Integration
We design and implement integrations that make your stack act like one product—whether you’re stitching together ERP/CRM, identity and SSO, payments, analytics, storefronts/marketplaces, or custom line-of-business apps. We start by modeling domains and data contracts, then choose the right patterns: synchronous APIs (REST/GraphQL) for user journeys, asynchronous messaging (events/queues) for scale, and webhooks with retries and idempotency for near-real-time updates.
Engineering discipline does the heavy lifting: API gateways and rate limits, schema versioning, secrets management, and end-to-end observability (success rates, p95 latency, queue lag, webhook delivery). We handle legacy (CSV/SFTP/EDI X12/EDIFACT), modern SaaS, and cloud services alike—wrapping fragile systems with stable interfaces. Security and compliance are built-in: least-privilege access, encryption, audit trails, and alignment with DPDP/GDPR, PCI-DSS, HIPAA, or ISO/SOC controls as needed.
Architecture That Scales Without Surprises
We separate real-time paths from batch workloads, define clear ownership boundaries, and use event-driven designs where they win on resilience and cost. Tooling includes API gateways, message brokers (Kafka/RabbitMQ), CDC for source-of-truth replication, and ETL/ELT into warehouses for BI. We bake in idempotency keys, backoff/retry policies, circuit breakers, and dead-letter queues to avoid duplicate writes and silent failures. Deployments follow blue/green or canary to keep downtime near zero. Every integration ships with dashboards for throughput, error budgets, and reconciliation health—so finance, ops, and product see the same truth.
From Discovery to Operate—With Documentation You’ll Actually Use
Engagements begin with a discovery map of systems, data flows, SLAs, and regulatory constraints. We deliver a reference architecture, sequence diagrams, and data dictionaries before writing code. Build phases include contract tests, sandbox runs, and controlled pilots. Operate means runbooks, on-call rotations where needed, and continuous improvement based on telemetry. Ektasi Labs can add ERP modules for procurement/inventory/finance and lifecycle messaging (email/SMS/webhooks) for alerts and customer comms; Virtunetic accelerates docs, SOPs, and multilingual support content so knowledge keeps pace with change.
Frequently Asked Questions
ERP/CRM (SAP, Odoo, Zoho, Salesforce), identity (SSO/MFA), payments, storefronts/marketplaces, logistics, analytics/BI, data warehouses, and custom apps.
Idempotent writes, retries with jitter, DLQs, health checks, and SLOs on success rate and latency with alerts to the right owners.
Yes—CSV/SFTP drops, scheduled batches, and EDI (X12/EDIFACT). We wrap brittle endpoints behind stable APIs and reconcile downstream.
Least-privilege IAM, key/secret hygiene, encrypted transport/storage, audit logs, and control mapping to DPDP/GDPR, PCI, HIPAA, ISO/SOC.
Shadow traffic, backfills via CDC, feature flags, and blue/green or canary releases with fast rollback paths.
Endpoint success/error rates, p95/p99 latency, queue lag, webhook delivery, data freshness, reconciliation accuracy, and business KPIs.
Yes—OpenAPI/GraphQL schemas, sequence diagrams, runbooks, and handover sessions so your team can operate confidently.
Discovery 1–2 weeks; first integrations 3–6 weeks depending on systems, security reviews, and certification needs.
