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:

Nga 47,080 vlerësimet, klientët vlerësojnë REST API Developers 4.9 nga 5 yje.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 am putting together a REST-style API built with PHP and a MySQL database. Its first job is to return user information quickly and in clean JSON, so the user endpoints should focus on efficient, well-indexed SELECT queries and clear response structures. Alongside those read-only calls, I also need a second group of endpoints for product details that can: • return existing records (GET) • add or modify items (POST / PUT) • remove items (DELETE) You are free to work with native PHP, Slim, Lumen, or a full Laravel setup—whichever will let you keep the codebase modular and easy to extend. Just keep the dependencies light and document any third-party packages you bring in. My acceptance check is simple: spin up the project, import the sample SQL I’ll provide,...

I have a live SwiftUI-based social app that already ships chat, video feeds, stories, live scenes, an in-app currency (stars) and subscription flow. The code follows MVVM, talks to a set of REST back-ends and is in the store today. What I need now is an experienced iOS engineer who can drop into the existing project, diagnose issues quickly and raise the overall quality bar. The immediate focus is three-fold: • First, do a thorough walkthrough of the current codebase so you understand our MVVM layers, networking helpers and IAP logic. • Next, remove bugs that are spiking our crash reports and tighten up general stability. • Finally, tune performance in the chat and media areas, then layer in a handful of small feature requests we already have queued for those modules....
I’ve completed the core gameplay and now need a global leaderboard that plugs cleanly into my existing Unity project. The board must fetch and display each player’s name, score, and rank in real time, and add a small country flag beside the name for quick geographic context.

I’m building a classic-looking web portal where visitors can quickly locate nearby pharmacies and, once there, browse the special promotions each pharmacy uploads. The public side centres on a postcode and distance search; users type a code or allow geolocation and see results ordered by proximity, complete with map pins and basic contact info. Behind the scenes every pharmacy will have its own password-protected area to maintain a short profile, upload time-limited promotions or evergreen deals, and decide when each offer goes live or expires. I need clean, semantic front-end code, straightforward navigation, and a back-office that even non-technical staff can use without training. Think classic layout: clear typography, familiar colour palette, no flashy animations—just a ...

I run our ground-transport operation on and now need all of our OTA and transfer partners to flow in and out of the system without manual work. Concretely, I want every new booking, change, or cancellation coming from Transferz, MyTransfers, Talixo, , Transfeero, Oulvgo, Kiwitaxi and CarTrawler to appear in automatically, then stay in sync through real-time webhooks. Codico already exposes REST endpoints for reservations, vehicles, drivers and trip status. Each partner publishes its own JSON/REST interface (some with polling, others with webhook callbacks). Your job is to map them one by one to Codico’s schema, build the middleware or micro-service that sits between the sources and Codico, and put solid logging and error handling around it so nothing is lost. Because this touches...
