Frequently asked questions
An API (Application Programming Interface) lets two software systems talk to each other — for example, your website charging a card via Stripe or syncing orders into your ERP.
REST exposes fixed endpoints returning predefined data; GraphQL lets clients query exactly the data they need in one request. We recommend the right fit based on your application.
Yes — we connect websites, mobile apps, ERPs, CRMs, POS and accounting systems, whether they expose modern APIs or need custom adapters.
Stripe, PayPal, PayHere, OnePay, WebXPay, Genie and more — including subscription billing and webhooks for payment events.
Yes — OAuth 2.0, JWT, API keys, HTTPS encryption, rate limiting, IP whitelisting, role-based access and audit logs are standard.
Yes — Microsoft Graph (Outlook, Teams, SharePoint, OneDrive) and Google APIs (Gmail, Drive, Calendar, Maps, Firebase) are among our most common integrations.
Yes — every API ships with OpenAPI (Swagger) documentation so your team and partners can integrate easily.
Yes — we upgrade legacy SOAP or monolithic APIs to modern REST/GraphQL microservices with zero data loss and phased migration.
