What our custom API development services include

Our team develops scalable and secure APIs that suit any business need, whether you’re planning to build a mobile or desktop app in the future, speed up your data-heavy website today, or access your data from various places and in various ways.

API design

For every API, we create a smart design that’s intuitive for developers to work with, a smart form of authentication, role- and route-based permissions, rate limiting, logging, and analytics.

API security

Our APIs are able to prevent, detect, and react to any security issues. We implement reliable identification, authentication, and authorization as the principal API security measures along with SSL and API traffic encryption.

API documentation

We draw up detailed yet simple API documentation for developers to describe the requests that are allowed to be sent, supported formats and types of data inputs, and the responses returned by the API.

Backend auto-scaling

We integrate a tool that monitors your API performance and automatically adjusts its capacity to maintain steady, predictable performance at the lowest possible cost.

Automated recovery

The automated recovery system that we implement in our clients’ custom APIs minimizes downtime and data loss by providing fast and reliable cloud-based recovery servers.

We build APIs to enrich and enhance software products

During development, we make sure the software products we create not only correspond to your current business needs but have the potential to grow and expand.


Pindify is a technologically advanced subscription-based marketplace that brings together creative providers and their audiences. We helped Pindify creators build a scalable, secure, and robust application that delivers exclusive creative content from artists, helping them make a living off their passion.

Compelling benefits you get when ordering our API services

When it comes to API development services, there are numerous advantages that make RubyGarage stand out.

Complete documentation for intuitive use

Our APIs let developers do their jobs faster, more easily, and with fewer resources. We pay a great deal of attention to the UX to ensure every API is easy for developers to work with.

Encrypted API traffic

API traffic encryption restricts access to sensitive information. We use SSL or TLS encryption to add another level of security and keep API keys secure.

Full rate-limiting control

We add an advanced control system to your API to prevent users from abusing it by scraping all your data or simply crashing your app by flooding it with requests.

Logging & analytics system

A logging and analytics system will help you monitor API usage. The API log file can record each request and response or only those that failed depending on your requirements.


Our APIs can grow or shrink their capacity depending on your team’s or customers’ needs. Your API can handle 100 users today and 10,000 tomorrow with no performance degradation.

High speed

We develop custom APIs that provide responses within 100 milliseconds – the average rate for successful APIs. This ensures the smooth and speedy work of your applications.

Smart authentication

Advanced authentication ensures access to your API is provided only to those who really need it, whether they’re paying customers, internal developers, or business partners.

Smart role- and route-based permissions system

Smart authentication rules enhance your API’s protection. We build role- and route-based permission systems to prevent unauthorized use of all or specific parts of your API.

Why we choose Ruby on Rails

Among numerous advanced technologies, we prefer Ruby on Rails due to a wide range of competitive advantages

Fast development Scalable Massive resources and community Reliable and easy to maintain High level of data protection Easy to support Flexible Cost-effective

How we create APIs for your product

We’ve established a logical workflow that helps us deliver quality APIs in the shortest time possible.

Stage 1. Development planning

Stage 1. Development planning

At the start of the project, we gather API functionality requirements, estimate the scope of tasks, establish a team, draw up a project budget, and create a release plan. At this stage, we:

  • Analyze business, functional, and technical requirements
  • Investigate the UX design
  • Refine features
  • Decompose features
  • Estimate tasks
  • Decompose the team
  • Create a release plan
Stage 2. Architecture design

Stage 2. Architecture design

To ensure a high level of software quality, maintainability, and scalability, we design the software architecture by creating style guides and describing the approaches to be used during API development. This stage includes:

  • Designing the backend architecture
  • Designing the API
  • Designing the database architecture
  • Selecting the technology stack and libraries
  • Selecting integrations
Stage 3. Development environment configuration

Stage 3. Development environment configuration

After we’ve planned the development process and the API’s structure, we move to configuring the tools and environment and setting up continuous integration. Preparing the ground for the development stage involves completing the following tasks:

  • Initializing a Rails application
  • Configuring and setting up the technology stack
  • Containerizing the application
  • Configuring development, test, and staging environments
  • Setting up a continuous integration server
  • Configuring deployment scripts
Stage 4. Custom API development

Stage 4. Custom API development

Multiple repetitions of sprint planning and the sprint implementation cycle help us establish a smooth and straightforward development process and minimize the development time. Both sprint planning and sprint implementation have their own objectives:

Sprint planning

  • Groom and actualize tasks
  • Design algorithms and business logic for each task
  • Create checklists for each task

Sprint implementation

  • Program and implement tasks
  • Create autotests
  • Review code
Stage 5. Production environment setup and product release

Stage 5. Production environment setup and product release

We prepare the project for release by applying load and security testing and configuring analytics and notification tools for monitoring, error reporting, and automated maintenance. The final stage consists of:

  • Designing production infrastructure
  • Configuring production infrastructure
  • Load testing
  • Auto-scale setup
  • Configuring integrations
  • Security testing
  • Configuring performance, quality, and availability monitoring tools
  • Releasing the backend API

Сlient testimonial

We’ve created lots of top-notch mobile, desktop, and web applications by equipping them with robust and solid APIs.
