Unity Developer For API Integration in Chess Game
Budget: $30 – $250 USD
I have a feature-complete chess game in Unity and now need an experienced developer to wire it up to the external services that make it production-ready. Your sole focus will be API integration—no work on art, board logic, or UI layout is required.
Here is what needs to come together:
• Payment gateways – set up in-app purchases so players can buy cosmetic items and subscription tiers directly inside the game.
• Social media login – enable one-tap sign-in with the major platforms listed in my docs, and make sure new accounts flow seamlessly into our existing user database.
• Leaderboard and ranking – plug in the service we use for global and friends-only leaderboards, display ratings inside the lobby scene, and keep them in sync after every match.
• Game flow endpoints – hook the existing start, resign, draw, and rematch actions to the backend so matches transition smoothly between states.
• Profile sections – pull player avatars, bios, and stats from the server and push updates instantly when users edit them.
I will hand over:
• A clean Git repo of the current Unity project (2021 LTS)
• Comprehensive REST and WebSocket API documentation with test keys
• Mock screens that show where each server call fits
You will return:
1. Fully integrated C# code and prefabs following the project’s coding standards.
2. Clear, step-by-step setup notes so another developer can build and test without guesswork.
3. A short video or GIF walkthrough proving each feature works on both Android and iOS builds.
Acceptance criteria: every listed feature must pass the automated Play Mode tests I provide and run without errors on the target devices.
If you’ve shipped similar live games and are comfortable juggling multiple third-party SDKs in Unity, I’d love to hear how you’d approach this and see examples of past integrations.
