When You Need Expert API Development

  • Building a SaaS product that needs a developer-facing API or webhook system?
    We design developer-friendly APIs with comprehensive documentation that accelerates adoption.
  • Struggling with unreliable third-party integrations that break your business workflows?
    We rebuild brittle integrations with resilient, monitored connection layers.
  • Need to connect your CRM, ERP, payment gateway, or marketing tools to your website?
    We integrate all major business systems through secure, efficient API layers.
  • Your API is too slow under high load, causing timeouts and poor user experience?
    We audit, optimize, and scale API infrastructure to handle your peak demand reliably.

API Architecture That Scales With Your Business

  • We design APIs following RESTful principles, OpenAPI 3.0 specifications, and security best practices — creating interfaces that other developers love to work with.
  • Proper API versioning strategy, rate limiting, and authentication design are built in from the start — not retrofitted later when scaling issues emerge.
  • We deliver complete API packages: specification, implementation, automated test suites, Postman collections, and developer documentation — everything your team and partners need.

Did You Know?

Every 100ms of API latency reduces conversion rates by 1% (Google). We benchmark all API endpoints, implement caching at every appropriate layer, and ensure response times that keep your application snappy under any load.

Testimonials.
We`re excited about their work and how they come to the table with ideas and feedback, which is invaluable...
INTEX agency has helped our startup to go from zero to one, contributing ideas and feedback beyond the app’s execution. The team is responsive and communicates effectively. They’re budget-conscious and trustworthy, and their enthusiasm for the client’s work has made them a true partner. Highly recommend!
...they are technically sound, grounded in all the best practices
We spent the last 6 months working with Intex, and I`m so glad that we found them. After we ran work tests with a bunch of agencies and Intex was by far and away from the most qualified and really earned my trust from the get-go. They converted our prototype to a pixel-perfect working website and built really intuitive backend to help the client manage the website. What impressed me most about working with Intex was just clear, honest communication. The guys were always dedicated, always available and even became a great sounding board for great UX ideas throughout the project. They are technically sound, grounded in all the best practices. I highly recommend them and look forward to more collaboration
...Deeply understood our business needs and had the right people in the team to execute our vision
The Intex team was instrumental in setting up a web-based survey form. They developed a very clean design and friendly user experience for our customers which we are delighted about. We are incredibly happy with communicating: zoom, emails, and of course any other platforms. The thing that I really enjoyed while working with Intex is that they were always on time, without any delays. They deeply understood our business needs and had the right people in the team to execute our vision. I would highly recommend anybody to work with them in the future.
...their work was done according to the highest standards and the result was much better than we expected.
We used the services from Intex to rebrand our website. The team came in with our brief and our new corporate guidelines. They were able to create a perfect new custom design for our website which they also implemented. The work they did was within the estimated budget. It was great to work with Intex, their work was done according to the highest standards and the result was much better than we expected. We highly recommend Intex agency, they are very knowledgeable and we will hire them for future improvements and updates as well.

Frequently Asked Questions

What technologies do you use for web development?

We work with modern, proven technologies: React, Next.js, Vue.js for front-end; Node.js, PHP (Laravel/WordPress), Python for back-end; PostgreSQL, MySQL, MongoDB for databases. Technology selection is always driven by your specific project requirements.

How do you ensure the quality and security of the code?

We follow industry best practices: code reviews, automated testing suites, OWASP security guidelines, HTTPS enforcement, input validation, and regular dependency audits. Every project includes a dedicated QA phase before deployment.

What is your development process?

We follow an agile methodology: discovery → architecture → development sprints → testing → deployment → monitoring. 2-week sprints with weekly progress updates ensure continuous delivery and total transparency.

Can you work with an existing codebase or platform?

Yes. We regularly audit, refactor, and extend existing codebases. Whether you’re on WordPress, a custom PHP application, or a React SPA — our developers can integrate, extend, or migrate your existing system efficiently.

Do you provide hosting and deployment services?

We manage deployments to your preferred cloud provider (AWS, GCP, DigitalOcean, Vercel) or work within your existing infrastructure. We also configure CI/CD pipelines for automated deployment workflows.

How do you handle project communication and transparency?

You receive a dedicated project manager, a shared project workspace in your preferred tool (Asana, Jira, ClickUp), weekly progress meetings, and real-time visibility into development progress. No black boxes.

What happens if I need changes or features added after launch?

We offer retainer agreements for ongoing development support or project-based engagements for specific features. Our team maintains comprehensive documentation to make future changes efficient regardless of timeline.

How do you ensure the website performs well under high traffic?

Performance is designed into the architecture: CDN implementation, database optimization, caching layers, image optimization, and load testing are all part of every production deployment. We verify performance benchmarks before launch.
