What do we offer?

PLANEKS provides API development and integration services. We can help you improve your project functionality for an adequate cost.

Custom API Development & Integration

What is Application Programming Interface (API)? Think of a custom API as a data pipeline that connects two systems. These interfaces allow businesses to leverage large amounts of information without having to store it within the application.

Third-Party API Integration

What is a third-party API? It’s the type of API that allows you to use services provided by another company (e.g., run ads on Facebook) or benefit from a technical solution delivered as SaaS. You don’t have to build a solution from scratch.
Who are we?

We are an offshore API development company with experienced programmers and wide domain expertise.

Do you need to integrate an existing API into your project?

API Integration Solutions

API integrations help companies automate day-to-day tasks, enrich their technical solutions, gain a better understanding of their processes, connect their systems, and overall—provide better services to the clients. Here’s how we can help you.

Payment Gateway Integration

Choose one or several of the many gateways and systems that provide secure and fast processing options. To process payments faster, automate recurring plans and subscriptions, integrate your application or existing eCommerce platform with leading payment gateway APIs like PayPal and Stripe to process payments faster.

Add a map from Google Maps, OpenStreetMap, Bing, or any other routing service to your website or mobile application for more straightforward navigation, precise locations of your destinations, traffic predictions, street view, and/or saved places.

Healthcare APIs

Integrate a HIPAA-compliant API with your existing system to manage patient data, automate mundane processes, and gain better insights into the operational activities. You can optimize registration, scheduling, and data management with secure APIs like Healthjump API, Redox, and NextGen Healthcare.

eSports APIs

Benefits of APIs and their integration

A properly developed or integrated API has multiple benefits to both the company and its customers. Here are just a few examples of the value API integration brings to any business.

Ease of Integration

APIs allow you to connect software components or even different systems easily. They share information, carry out various tasks, and streamline processes.


APIs are integral to modern systems and the digital transformation of legacy platforms, allowing businesses to transform their existing services.

Cost Reduction

Instead of complex software developed from scratch, companies can enjoy the benefits of existing solutions integrated via APIs.


APIs allow you to streamline and automate recurring processes and operations without dealing with them on your own.

Faster Development

If you are working on complex software or application, API integration allows you to speed up the development process and reduce the time-to-market significantly.

Access to a Large Amount of Data

You don’t have to create complex data solutions when you can access technical solutions someone has already created.

Technologies we use for API integration

One of the biggest challenges in API development and integration is to ensure fast and secure connectivity, along with stable performance. Typically, we use a a certain tech stack for API integration.


REST API is one of the most widely used options in public APIs. It is often a go-to option for social media APIs, location and navigation APIs, and other common services. It is highly flexible and can work with any data format (including XML, JSON, YAML, or any other).


JSON relies on universal data structures to easily transmit and parse information and works well with almost any client application. It allows engineers to manage multiple data formats and multiple APIs at the same time.


SOAP protocol is often used in the enterprise-level API to provide secure transmission of data. It’s the preferred choice for payment gateways and financial platforms, CRMs, and software solutions that deal with identity management. It requires solid experience and an in-depth understanding of procedures for successful development.


Effective API technology stack

Take advantage of our expertise to speed up development processes and enhance the capabilities of your application.


Industries we work with

Our portfolio includes projects for over 20 industries. We have successfully delivered projects for fintech, media, business services, hospitality and leisure, and many other companies.


One of the main uses of APIs in healthcare is integration with electronic health records (EHR) and electronic medical record (EMR) systems, allowing secure access and management of patients’ data.


Add single-sign on and get better data analytics with custom APIs. For example, we have integrated Twitch into one of the projects, allowing the login, data management, and extensions management.


Most eCommerce platforms (like Amazon or eBay) provide their own APIs. We have recently worked with the API that processes customers’ reviews, payments, and invoices.


Manufacturing companies can also benefit from integration with third-party services.
We successfully integrated Autodesk Forge API with the client’s existing services.
