Job Title: eBay REST API (Buy Browse) & ePN Tracker Setup

Source: reddit-r-forhire
Compensation: £80–100 (Paid via Fiverr, PayPal Goods & Services, or bank transfer)

About the Role

I am looking to hire a backend developer for a short-term, specific integration project for carddropx.com. I have a clear, highly structured technical brief ready, and I will handle 100% of the manual KYC, compliance paperwork, and eBay developer reviews myself. I only need you for the clean code and environment configuration.

Location

Remote: Open to remote applicants.
London (UK) Bonus: If you are based in London, there is an option to grab a free meal or shisha to discuss future work potential.

Scope of Deliverables

API Keysets: Configure Production/Sandbox environments and set up the OAuth RuName callback URI (https://carddropx.com) in my eBay Developer portal.
Buy Browse API: Provide a working, lightweight script (Node.js or Python preferred) demonstrating a working token refresh loop and data fetch.
ePN Linking: Map out the multi-market link structures (US, UK, DE, FR, IT) ensuring the target parameters inject EBAY_CAMPAIGN_ID and EBAY_CUSTOM_ID=carddropx safely into ebay.com payloads.
Documentation: Deliver a brief markdown file detailing eBay’s strict rate limits for these endpoints to ensure thresholds are not exceeded.

Requirements

Experience working with RESTful APIs, OAuth 2.0 flows, and token lifecycles.
Ability to deliver clean, commented, and reusable scripts.

How to Apply

If you are interested, please comment with a link to your GitHub or previous API integration projects. If you are in London, please include your general borough.
