API Integration & Development Services
Belitsoft's API engineers have extensive expertise in nearly all types of API development and integration tasks. We develop APIs, make them more public & accessible, and integrate internal and external systems through APIs. Our API development agency also designs and implements well-defined APIs for machine learning tools.
Custom API development and integration
We create custom APIs to improve the existing software, making it easier to share data in real time and automate workflows.
If you're looking for custom application development companies to handle your API development and integration tasks, consider hiring a dedicated development team of experienced API specialists from Belitsoft.
When a suitable ready-made API is not available or does not fit your needs or you want to integrate your application with an interface of an existing API, our expert API developers will bridge the gap between your platform or app and the critical information and data you need to succeed.
We're experts in various API services including REST and GraphQL and we've got experience in programming high-speed, large-scale API projects.
API consulting
If API-related decisions stretch your internal resources to their limits, invest in our API integration and development consultants to help you make the right technical decisions and meet your expectations.
Our technology experts, known for their commitment to excellence, include API strategists, enterprise architects, cloud developers, and API modernization specialists.
Before creating APIs for client-facing or server-side apps using open-source or proprietary tools, they conduct business analysis, technology assessment, API strategy, and design.
As the owner of the resulting products, you will understand what’s going on at every stage of the project.
We help you find, develop, or review API services tailored to your unique needs, ensuring your product compliant with strict regulatory and security requirements.
LLM API Integration
Belitsoft integrates NLP capabilities into your software (for example, by connecting to services like OpenAI and language models like ChatGPT) and develop AI applications. We build API layers to receive requests from your apps, forward them to the LLM, and deliver the response back to your application after the ML model processes it. This will allow your app to generate content (answer questions, perform sentiment analysis, summarize large documents, etc.) and trigger real actions through APIs (create tasks, update records, call services, etc.). Our security engineers will protect your data in transit (implement security protocols to encrypt information, establish access control policies for authorized users, and remove sensitive information). They help you lower costs and improve performance through token optimization and by monitoring response time, latency, and error rates.
Mobile API development
We create APIs to extend the functionality of your mobile apps, enabling payments, appointments, geolocation, and more. Get integration of data from multiple sources (servers, databases, GPS, or messaging systems) right into your mobile app. To make APIs lightweight, we use compact data formats like JSON, reduce the number of requests by batching them, compress API replies, avoid pointless data transformations, and cache API answers in the mobile device’s memory. We secure your APIs and protect sensitive data with HTTPS, token-based authentication, input validation, rate limiting, and access control.
Web API development
We develop or integrate web APIs to share data with remote third-party web apps through the HTTPS protocol over the internet. The REST architecture is used to retrieve, post, update, and delete data. The API platform provides an access token to receive requests, and the app parses the responses to extract the data you need. Users will access payment gateways, social media, email, geolocation, sports, weather, video streaming, cryptocurrency platforms, or whatever you wish. The latest real-time, up-to-date information from various sources is displayed on their app.

Frequently Asked Questions
APIs are used by programmers to enable access from one app or platform to another or integrate different applications.
There are different types of APIs: for applications (Google Maps API, Facebook API, Twitter APIs, LinkedIn API); for a web-based system or a website (Amazon, eBay); for operating systems (POSIX is for Linux and Berkeley Software Distribution, Microsoft Windows API); for a database system; for computer hardware; for a software library.
Also, there three main policies for releasing APIs: private (for internal use), partner (for business partnerships), and public (for public use).
Each API goes with documentation where all the information on what the services API offers and how to use them is given.
API integration allows you to:
- Build things by assembling pieces together in novel ways
- Connect legacy systems with modern technology and extend the life of your existing tools with custom integrations—without overhauling everything or replacing still-useful applications
- Automate processes to spend less time on repetitive tasks and stop wasting time jumping between multiple platforms
- Integrate with third-party apps, which provide real-time functionality, without writing your own complex algorithms (this is true for e-commerce, finance and other industries)
- Integrate web/mobile apps with cloud storages
- Integrate mobile apps with remote backends to push files and retrieve data.
- API builders have complete control over the API. The team that built the new algorithm can use a web API to sell access to it without giving away their intellectual property in the form of a library with open code.
- Building a web API also allows to sell the powerful functionality of a system that requires extraordinary computational power, like machine learning APIs, to consumers with the standard computational resources of their home computers or laptops.
