We connect your ERP, CRM, online store, payments, accounting and messaging tools with secure APIs — so data flows automatically and your team stops copying and pasting.
Most businesses run on many separate systems — an ERP, a CRM, an online store, accounting, payments and messaging. When they don't talk to each other, people re-type data, mistakes creep in and reports never match.
TECHTARN provides API integration and system integration services that connect everything securely. We build custom APIs, integrate third-party platforms, sync data in real time and automate workflows — on reliable infrastructure managed by our cloud & DevOps team.
⚠️Data copied by hand between six systems — slow, error-prone and impossible to scale.
Twelve services, presented the way developers think — as endpoints for your business.
/apis/custom›Secure, well-documented REST and GraphQL APIs for your products, partners and mobile apps.
/integrations/third-party›Connect your systems to any external platform with a public or partner API.
/integrations/erp›Sync orders, stock, invoices and customers between your ERP and every other system.
/integrations/crm›Leads, contacts and deals flowing automatically between your CRM, website and sales tools.
/integrations/payments›Cards, wallets, bank transfers and local gateways with secure, reliable checkout.
/integrations/ecommerce›Connect stores and marketplaces with inventory, shipping and accounting.
/integrations/accounting›Invoices, payments and journals posted automatically to your accounting system.
/integrations/messaging›WhatsApp, SMS, email and voice notifications triggered by real events.
/integrations/legacy›Bring old desktop, on-premise and database-only systems into a modern connected stack.
/automation/workflows›iPaaS and middleware flows that move data and trigger actions across teams.
/webhooks/realtime›Event-driven updates so every system sees changes in seconds, not hours.
/gateway/monitoring›Authentication, rate limiting, logging and alerts for every connection.
