Looking for an API Integration Expert I am looking for an experienced API developer who can help me integrate one website with multiple marketplaces. I am a digital products and software license seller, and I want to automate product listing and management across different platforms using APIs. Required skills: - API integration between websites and marketplaces. - Product listing creation and updates through APIs. - Automatic price and stock synchronization. - Order processing and digital license key delivery. - Experience with REST APIs, webhooks, and marketplace APIs. - Ability to build a reliable, scalable, and automated solution. I already have access to the APIs for my source website and marketplace platforms. I need someone who can understand the API documentation and build the complete integration. If you have relevant experience, please contact me with examples of your previous work, estimated cost, and timeline. I am looking for a reliable expert for long-term cooperation.
