SIFR SOFTWARE TECHNOLOGY
API Integration & Application Communication
Practical API and server-to-server integration for applications that exchange data securely.
API integration in practice
Applications rarely work alone. Sifr Software builds and connects systems that exchange data securely with banks, payment processors, SMS and WhatsApp gateways, accounting packages such as Tally, and other web services. Integration is done with explicit, versioned contracts so a change on one side does not silently break the other.
⚡
Webhooks & callbacks
The other system is notified when an event happens, instead of having to poll repeatedly.
🔐
Server-to-server security
OAuth 2.0 client credentials, API keys and signed requests protect machine-to-machine calls.
▣
Tally & accounting links
Bills, ledgers and payment data can flow into Tally or other accounting packages used by the business.
⇄
Two-way sync
Master data such as customers, items and rates stays consistent between connected systems.
⏱
Monitoring & logging
Integration runs are logged so failures can be traced and retried without exposing the user.
