API Development is an effective way for software to communicate and interact with each other over the internet. It’s a great way for developers to expand the capabilities of a program or systems by creating interfaces and allow data to be shared between different types of technology. With an API, existing systems can connect and more advanced solutions can be made. Hiring an API Developer can enable businesses to streamline processes and enable a much faster integration of existing software solutions.

API Developers are skilled engineers specialized in creating new APIs and maintaining existing ones. They are responsible for developing and troubleshooting current APIs, designing APIs from standards-based web services, maintaining inventory and implementing authorization mechanisms. Additionally, they incorporate different technologies together to create advanced software solutions that integrate cloud systems like Amazon Web Services or MongoDB and APIs with point-and-click platforms, like WordPress or HubSpot.

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

  • Creating advanced databases on different cloud systems
  • Linking between two cameras from a microscope
  • Interfacing with customizing Wordpress themes, Woocommerce themes and SMS services
  • Building secure back end systems to analyze different public APIs
  • Applying sophisticated authorization mechanisms
  • Creating comprehensive ecommerce websites using MERN Stack
  • Developing node APIs for exchange markets using Node.js, Web3.js, Ether.js
  • Automatically out of stocking items from supplier’s stock through an API system.

It is no surprise that good API Development is the cornerstone of many successful software solutions. Our expert API Developers are well experienced in developing suitable solutions for projects ranging from app development to SaaS applications, game development to enterprise system integrations.

    I need a self-contained module that lets my web application talk to a TRC20 wallet through a direct Binance connection. Once wired up, the user must be able to: • Send and receive TRC20 tokens • View a complete, paginated transaction history • Check their live account balance in real time The front end is currently React, with a Node back end, but I’m happy for you to bring your own stack as long as it uses stable libraries such as TronWeb, or the official Binance API and keeps private keys on the client side. Your code should be clean, well-commented and easy for another developer to drop into a Git repo, run `npm install`, and be up and running with minimal configuration.

This website already contains barbers’ calendars, where clients can book time slots (for example from 1:00 PM to 2:00 PM for a haircut). In the barbershop, there will be a mirror screen that displays the appointments. The principle is the following: • When a client books a time slot on the website, the appointment automatically appears on the mirror screen. • However, if the barber modifies something directly in the calendar (changing the service, modifying the time, etc.), these modifications should not appear on the mirror screen.

    Hello I’d like to clarify the backend scope for the **Hotel Automation Platform** so we’re aligned before starting. Main Responsibilities: 1️⃣ Webhook Processing Receive bookings from **Channel Manager (Account A)** via webhooks and process them in an **event-driven** way to prevent duplicate processing if the same webhook is received more than once. All events should be logged in **AutomationLogs / SystemLogs** for traceability. 2️⃣ Automation Engine Apply rules to each booking, such as: * Commission deduction * Price adjustment (seasonal or promotional) * Additional fees (e.g., cleaning fee) * Guest data adjustments if needed 3️⃣ Virtual Card Service Generate a **Virtual Credit Card (VCC)** for each booking and link it to the booking record. The system should be ready t...

    I need an experienced developer to turn JotForm submissions into fully-automated workflows inside Salesforce—and, where useful, replicate the same logic for Zoho CRM and HubSpot. This goes well beyond a basic form-to-lead setup. When a prospect fills out a form I want three things to happen seamlessly: • A branded follow-up email is sent from Salesforce, personalized with the data the visitor just entered. • A task is created (or updated) for the assigned rep so nothing slips through the cracks. • Key fields stay in sync between the form and the CRM, updating both directions in real time. You’re free to use webhooks, native JotForm integrations, the Salesforce API, Flow Builder, Zapier, Make, or custom code—whatever delivers the most reliable, maintai...

    I have a MySQL database that stores stock-market-related records. I need a lightweight script or micro-service that will: • Query the required rows on a schedule or on demand, • Convert the result set into a clean JSON payload, and • Push that payload to a remote endpoint via a standard webhook (HTTP POST with a bearer token). The table structure is already in place; I will explain the field names you should map. The JSON shape has to match a small schema I’ll share, but it is simple key-value pairs—nothing nested beyond one level. Code can be in Python, Node.js, or PHP as long as it runs reliably on a Linux server. Use parameterised queries (or an ORM if you prefer) so there is zero risk of SQL injection, and make sure any credentials sit in an external c...

    No errors appear on the frontend, yet the records never land in the backend, so the breakdown is clearly in the API hand-off from to ERPNext. I need someone who truly understands both the Frappe REST API and modern (React 18, Node, TypeScript, Axios/fetch) to trace the request flow, pinpoint the failure, and deliver a clean, tested patch. I am happy with the existing codebase otherwise, so the job is strictly about restoring reliable, real-time syncing in that one direction. Please plan to: • audit the current integration layer and identify the exact call or webhook chain that drops the merchant payload • implement the fix (whether that means adjusting authentication, request formatting, or ERPNext endpoint configuration) without breaking anything else • add a qui...

    Shynocell will be a one-stop shop where customers can buy mobile credit (pulsa), data packages, and top-up popular mobile games such as Mobile Legends. The flow I have in mind is simple: a visitor selects the product, pays via the built-in QRIS gateway—or, if they prefer, through Bank Transfer or an e-wallet—and the order is sent instantly to the Metro Reload API for fulfillment. As soon as Metro Reload confirms success, the system should mark the order complete and email/SMS the customer automatically. Key elements to build: • API layer that authenticates, sends, and tracks transactions with Metro Reload. • Payment module supporting QRIS first, then Bank Transfer and common Indonesian e-wallets. • Admin dashboard where I can add or disable products, adjust...
