REST, GraphQL, webhooks, and third-party integrations — we design, build, and connect APIs that power your business systems seamlessly.
Build Your APIAt Syntektra Solutions, we build and integrate robust, scalable APIs that serve as the backbone of modern applications. Whether you need a brand new REST or GraphQL API, or need to connect your systems with third-party platforms, payment gateways, CRMs, or cloud services — we handle it end to end.
Our API development follows industry best practices — versioning, rate limiting, authentication, documentation, and testing are built in from day one. We have delivered API integrations across fintech, healthcare, e-commerce, IoT, and SaaS platforms.
Clean, well-structured RESTful APIs following OpenAPI 3.0 specification. We implement proper HTTP methods, status codes, pagination, filtering, sorting, versioning, and HATEOAS principles. Documented with Swagger UI for easy consumption.
Flexible GraphQL APIs with schemas, queries, mutations, subscriptions, and resolvers. We implement DataLoader for N+1 query prevention, persisted queries, and schema stitching for federated architectures.
Real-time event delivery using webhooks with retry logic, signature verification, and delivery tracking. We design event-driven architectures using message queues (SQS, RabbitMQ, Kafka) for reliable async communication.
Stripe, Razorpay, PayPal, Braintree, and other payment gateway integrations. We handle one-time payments, subscriptions, refunds, webhooks, and PCI-compliant checkout flows.
Integration with any third-party service — CRMs (Salesforce, HubSpot), ERPs (SAP, Oracle), communication platforms (Twilio, SendGrid), social media APIs, mapping services, and more.
OAuth2, JWT, API keys, HMAC signature verification, mutual TLS, and rate limiting. We secure every endpoint against common threats including injection, broken authentication, and excessive data exposure.
Deploy and manage APIs through AWS API Gateway, Kong, or NGINX. We configure routing, throttling, caching, request transformation, and usage plans for internal and external API consumers.
Comprehensive API documentation using Swagger UI, Redoc, or Postman collections. Interactive docs that let developers explore and test endpoints directly — reducing integration time significantly.
We build API wrappers and middleware layers around legacy systems, SOAP services, and databases — exposing them as modern REST or GraphQL APIs without touching the underlying system.
Real-time API monitoring with latency tracking, error rate alerting, usage analytics, and SLA reporting. Integrated with CloudWatch, Datadog, or custom dashboards to keep your APIs healthy.
