# Relationship Tools - Development Notes ## Critical: API Endpoint Path Difference The Quickbase Relationships API uses **different pluralization** for read vs write operations: | Operation | HTTP Method | Endpoint Path | |-----------|-------------|---------------| | Get relationships | GET | `/tables/{tableId}/relationships` (plural) | | Create relationship | POST | `/tables/{tableId}/relationship` (singular) | | Update relationship | POST | `/tables/{tableId}/relationship/{relationshipId}` (singular) | | Delete relationship | DELETE | `/tables/{tableId}/relationship/{relationshipId}` (singular) | This was discovered through live API testing - the OpenAPI spec and official docs don't clearly call this out. Using the wrong form results in HTTP 404 errors. **Reference**: Verified against [node-quickbase](https://github.com/tflanagan/node-quickbase) library which is autogenerated from the Quickbase OpenAPI spec.
