Build robust APIs and integrate third-party services seamlessly into your technology stack.
Our API development services help businesses connect disparate systems, automate workflows, and create unified platforms. We specialize in RESTful APIs, GraphQL, gRPC, microservices architecture, and third-party integrations including payment gateways (Stripe, Razorpay, PayPal), CRMs (Salesforce, HubSpot, Zoho), ERPs (SAP, Oracle, NetSuite), communication platforms (Twilio, SendGrid, Slack), cloud services (AWS, Azure, GCP), social media APIs (Facebook, Instagram, LinkedIn, Twitter), and marketing tools.
We follow industry best practices including OpenAPI/Swagger documentation, OAuth 2.0 and JWT authentication, rate limiting and throttling, comprehensive error handling, API versioning, automatic retries with exponential backoff, circuit breakers, and detailed logging and monitoring. Our team ensures secure, scalable, and well-documented APIs that power your digital ecosystem and handle millions of requests per day with sub-100ms response times.

What you get when you partner with us on API Development & Integration.
Certified senior engineers with 10+ years building Solution systems for regulated and high-growth businesses.
From discovery and design through implementation, deployment, and steady-state operations — one accountable team.
Two-week sprints with working demos, transparent burn-downs, and outcomes you can measure each fortnight.
Distributed senior teams in India, UK, US, and UAE — your delivery window matches your business hours.
ISO 27001 certified processes, SOC 2 ready, GDPR and HIPAA-aware controls baked in from day one.
Fixed-bid, time-and-material, dedicated squad, or staff augmentation — we match the model to your reality.
We map your business goals, current state, constraints, and the success metrics that matter to you. Output: a written brief with prioritised use-cases.
We define the right approach, target architecture, and a phased delivery plan with clear milestones, dependencies, and risk register.
Our architects design solutions that are scalable, secure, observable, and maintainable. We share the design with your engineers for review.
We build in bi-weekly sprints with working demos, automated testing, and code reviews. You see progress every two weeks, not at the end.
We roll out with zero-downtime strategies — blue-green, canary, feature flags — and a documented rollback plan for every release.
We hand over with full documentation and runbooks, then stay engaged for support, optimisation, and continuous improvement.
Tools and platforms we use day-to-day for API Development & Integration. We are tool-agnostic — we pick what fits your stack.
Most engagements scope between 6 and 16 weeks depending on the size of your environment and the use-cases in scope. We share a phased plan with milestones during the discovery sprint, and we are explicit about what is included and what is not.
We support fixed-bid for well-scoped work, time-and-material for evolving work, and dedicated-squad for long-term partnerships. Pricing is based on team composition, duration, and delivery model — we share a transparent cost breakdown before commit.
Both. We can run delivery end-to-end with an accountable Ketpy squad, or we can embed senior engineers into your existing team. Many of our clients start with end-to-end and transition to a hybrid as their internal capability grows.
We are ISO 27001 certified with SOC 2 controls. We sign NDAs and DPAs upfront, follow least-privilege access by default, audit-log every action, and never offshore your data without written approval. For regulated industries we follow HIPAA, GDPR, RBI, and SEBI guidance as applicable.
Tell us what you are building and we will get back inside one business day with a written brief and a recommended next step.
