Custom ERP API Development
Budget: $10 – $30 USD
I am expanding my in-house ERP and need a clean, well-documented API for several custom modules that sit alongside our existing inventory, HR, and accounting areas. The current system already exposes sandbox and production endpoints with separate keys, so your work must plug neatly into that dual-environment pattern.
Core requirement: the new endpoints must handle user authentication using an API Key strategy. If you want to architect them so we can add OAuth2 or JWT later, that future-proofing is welcome, but for now the live build must rely only on API Keys.
You will create the APIs and test the endpoints, then hand over concise documentation that shows other developers exactly how to hit sandbox versus production, obtain or rotate keys, and handle typical error responses.
Deliverables
• Source code for the new API endpoints
• Postman (or similar) collection demonstrating each call in both environments
• Setup notes and quick-start guide for other teams
• Brief security checklist confirming API Key handling and storage best practices
Deploy code via GIT and update changelogs
For the modules, please refer to the attached pdf file and existing api.
