API Integration Service

Custom API Integration

Whether you're building a new application or improving an existing system, seamless API integration is crucial for modern digital operations. At Nextin, we specialize in integrating third-party APIs into your platform—securely, efficiently, and tailored to your exact workflow.

From payment gateways and SMS services to shipping partners, WhatsApp Business APIs, and external CRMs—we connect your system to the tools your business depends on. All integrations are custom-coded using PHP and JavaScript to ensure performance, data integrity, and security.

Payment Gateways

Integrate Razorpay, Stripe, PayPal, CCAvenue, or custom gateways into your website or billing software with secure validation.

WhatsApp & SMS APIs

Send transactional messages, OTPs, and automated alerts using WhatsApp Business API or SMS platforms like Twilio or MSG91.

Shipping & Logistics

Track orders and automate shipment creation with Shiprocket, Delhivery, Blue Dart, and other courier API integrations.

CRM & ERP Systems

Connect your website or dashboard with Zoho, HubSpot, or other CRM/ERP platforms to automate lead and customer data sync.
