REST APIs are the interface between clients and servers that allows for data to be shared across platforms, providing a seamless connection between applications, databases, and other resources. A REST API Developer is the programmer who helps clients connect their applications to a certain platform and ensure data is flowing between the two in an efficient, secure manner. This can help to reduce friction, improve performance & scalability, boost security, streamline website navigation, and more.

REST API Developers build and maintain custom programming to enable automated data retrieval and communication with a client’s desired application or platform. This can encompass services such as quickly integrating third-party payment systems into an existing website, minimizing manual work and improving customer experience. They may also incorporate priority systems; for example creating different APIs for handling bulk vs single requests for heavy workloads. Ultimately a REST API Developer helps clients bridge the gap between complex platforms and transform data into valuable business insights.

Here’s some projects that our expert REST API Developers made real:

  • Establishing communication between different applications
  • Creating priority systems for managing large volumes of requests
  • Integrating third-party payment systems into an existing website
  • Developing programming to seamlessly retrieve dynamic data
  • Designing secure connections to protect confidential information

Our highly-skilled REST API Developers are experts when it comes to stitching together the critical links which connect disparate platforms together. With years of experience they have been able to tackle innumerable projects which have led to successful outcomes for our clients. If you have an issue related to connecting your application with another platform or require automated data retrieval services then you can post your own project here on Freelancer.com and hire one of our experienced developers today!

    I’m looking to partner with a versatile developer who is equally comfortable writing clean Python on the back end and crafting polished interfaces with HTML / CSS, JavaScript, and React on the front end. You’ll join me on a project-by-project basis, so the exact feature set may shift from one engagement to the next, but the common thread is always a Python-driven web application that needs a modern, responsive UI. Typical tasks could include: • Building or extending RESTful endpoints in Python • Wiring those endpoints into dynamic React components • Styling the resulting views so they look crisp across devices Clean, well-documented code and clear Git commits are essential, because other team members may pick up where you leave off between phases.

    I run a Laravel 10 Xtora-based top-up site that sells Mobile Legends diamonds. I want to take the manual work out of the entire purchase flow, from payment confirmation to diamond delivery. What needs to happen 1. The moment a customer completes a transfer to my BOB Bank account, the system should detect the transaction through the bank’s API (or any webhook the bank exposes) and instantly mark the related order as paid. I am not yet sure whether BOB provides full documentation, so you may need to help me confirm their capabilities and handle authentication, polling, or webhook endpoints accordingly. 2. As soon as an order is paid, the site must call UniPin’s supplier API to deliver the correct diamond package to the player’s UID, then update the order status in Larave...

    I’m expanding our mobile team and need a Flutter front-end developer who can take full ownership of the customer-facing side of a new e-commerce app. The work is 100 % Flutter, so solid Dart fundamentals and at least two years of hands-on experience are non-negotiable. You’ll be shaping every screen in line with our in-house Custom Design System, not off-the-shelf Material or Cupertino components, so an eye for detail and comfort with bespoke styling is essential. Scope of work You’ll turn Figma mock-ups into smooth, production-ready code, wire the UI to the REST endpoints our back-end team exposes, and make sure performance holds up across Android and iOS. While the app may later grow into social or utility features, your immediate focus is strictly e-commerce. Core ...

    Node.js Loan Backend Build

    I am assembling a new loan-processing platform and need a seasoned Node.js developer to stand up the entire backend. The core of the job is to architect and code secure user authentication and authorization, handle the full life-cycle of a loan application form, and build reliable payment processing with clear tracking of every transaction and status change. For data persistence I would like you to work with a SQL database—MySQL or PostgreSQL are both fine—so please structure your models and migrations accordingly. Beyond our own data store, the service must connect smoothly to several third-party providers: a credit-score API to pull applicant scores in real time, a payment gateway for disbursements and repayments, and notification services that let us push SMS and email upda...

    I need a cross-platform mobile application delivered for both Android and iOS within roughly four to six weeks. The stack can be either Flutter or React Native, but whichever route you choose must integrate smoothly with a REST-based API layer and rely on Firebase or MySQL on the back end.

    I’m creating an online destination where soccer enthusiasts can check reliable, data-driven match predictions before every kick-off. The engine behind the site will combine large sets of historical match data with up-to-the-minute season statistics, feeding them into a machine-learning model that outputs win-draw-loss probabilities and scoreline estimates. What I need from you is the full build: model selection or custom architecture, data-pipeline automation that fetches and refreshes both the historical archive and the current-season feeds, and a clean web interface that presents predictions in an easy, fan-friendly format. Odds-style percentages, form graphs, and key player influences should surface prominently so visitors can grasp the rationale behind each forecast without re...

    Indian Language Dictionary App

    I have a complete, well-structured glossary of Indian local-language terms and definitions ready to load into a brand-new mobile dictionary. What I need now is the actual app—clean, fast and intuitive—running on both iOS and Android from a single codebase. Core experience I want the user to have • Instant search that returns relevant matches as the user types • Smooth browsing by thematic categories (I will supply the categories) • A daily “Word of the Day” card, ideally with an optional push notification Community input matters too. Users should be able to suggest new words or edits, but nothing goes live until I approve it in an admin screen or lightweight web dashboard. I will hand you the full content as JSON/CSV along with basic UI refer...

    I need a developer who can connect the AGDC (PM USA) scan-data feed with the R.J. Reynolds loyalty program and have both flow cleanly into my existing CRM and e-commerce platform. The aim is to streamline day-to-day operations by keeping customer information, transaction details, and loyalty points perfectly in sync—no manual exports, no batch uploads, just real-time accuracy. Here is the workflow I’m picturing: when a customer purchase is scanned, the data should automatically populate our CRM record, update loyalty balances in the RJR program, and reflect the same information on the storefront side of the e-commerce system. Any change in one system must instantly show up in the others. I’m open to the underlying mechanics—REST or GraphQL APIs, middleware like Zap...

    I have a small iOS / Android app that was built years ago and never truly launched. The code still compiles, yet everything—from the visuals to the underlying logic—feels frozen in time. I now run an up-to-date website and I’m ready to bring the mobile experience in line with it. Here is what I need: • Refresh the full app • Introduce modern AI-driven capabilities where they make sense (for example, personalised recommendations and smart search). • Update all workflows and data handling to satisfy today’s regulatory requirements in our sector. • Ensure design, navigation and interactive elements look and behave like the site, using current iOS and Material guidelines. • Optimise performance and codebase for the latest OS versions,...
