API Development

The bridge between your systems and the world

A well-built API is what lets your mobile app, your website, your ERP and your partners' services exchange data securely and in an orderly way. A poorly-built API is an open door to problems. At Capa7 we design APIs with security, documentation and performance from day one β€” with a team that has been building backend systems since 2009.

We Are Specialists

It's Not Just Returning JSON: It's Doing It Right

Designing an API that is secure, fast, versioned and easy to consume takes real craft. We have that craft, and we back it up with the infrastructure where we run it.

  • Real Security

    Token-based authentication, role-based access control and usage limits to prevent abuse.

  • Clear Documentation

    Every endpoint documented so your team or your partners can integrate it without guessing.

  • Sensible Versioning

    We evolve the API without breaking whoever already uses it. Controlled changes, no surprises.

  • Our Own Infrastructure

    We host it on our own rack in Miami: performance and support from a single responsible team.

What We Do

APIs for Every Need

Custom REST APIs

Designed for your business, with the endpoints your operation actually needs.

Backend for Apps

The engine behind your mobile app: data, users and business logic, served fast.

Integration APIs

We connect your systems with third-party services: payments, messaging, logistics and more.

Authentication and Security

Tokens, OAuth, role-based access control and usage limits to protect your data.

Documentation and Portal

Living documentation so anyone consuming your API knows exactly how to use it.

Maintenance and Scaling

We monitor, version and scale your API as its usage grows.

Use Cases

When You Need an API

You Have or Want a Mobile App

Every serious app needs a backend with an API. We build it for you, secure and fast.

Partners That Consume Your Data

Distributors or partners who need to query your information in a controlled way.

Multiple Systems That Don't Talk to Each Other

A central API lets all your systems share data without chaos.

Integrate Payments or Services

Connect payment gateways, messaging or any external service to your platform.

Open Up Your Platform

Offer a public API so third parties can build on top of your product.

Modernize an Old System

Add an API to a legacy system to connect it with the new.

Question?

What is an API and why do I need one?

It's the gateway through which your systems and third-party systems exchange data in an organized, secure way. You need one if you have a mobile app, want to integrate external services, or need multiple systems to share information.

How much does it cost to develop an API?

It depends on how many endpoints and what integrations you need. We start with an analysis and give you a clear proposal with timelines and costs. The initial conversation is free.

Do you document it?

Yes, always. An API without documentation is impossible to maintain and integrate. We deliver clear documentation for every endpoint.

Does it integrate with my current systems?

Yes. We design the API to work with what you already use β€” your ERP, your accounting software, your database β€” and with external services like payment gateways or messaging.

Do you host it?

We can. We deploy it on our own infrastructure in Miami, with support from the same team that built it. We can also hand it over so you can host it wherever you prefer.

What happens when I need changes?

We version the API to add or change things without breaking whoever already uses it. We offer maintenance plans so it evolves with you.
