# ERPLab

> ERPLab hosts high-fidelity, tenant-isolated ERP simulators (Oracle Fusion Cloud ERP and more) with the same REST, SOAP and OAuth 2.0 integration surface as the real vendors, so integration code can be built and validated end-to-end without a production ERP.

Each simulator is served under a tenant-specific base URL of the form `https://erplab.cloud/sim/{environmentKey}`. Sign in at https://erplab.cloud/auth to obtain an `environmentKey` and OAuth 2.0 client credentials for your tenant. Public documentation and OpenAPI specifications below describe the exact endpoints, payload shapes, query grammar, error envelopes and workflows every simulator exposes; they are the authoritative contract.

## Docs

- [Oracle Fusion Cloud ERP — integration documentation](https://erplab.cloud/public/oracle-fusion): Human-readable reference: authentication, REST resources, SOAP services, query grammar, errors, workflows and capability matrix.
- [Oracle Fusion Cloud ERP — OpenAPI 3.1 specification](https://erplab.cloud/api/public/oracle-fusion/openapi.json): Machine-readable API contract. Use this to discover endpoints, request/response schemas, path/query parameters and security schemes.

## Task guides

- [Oracle Fusion — External Provider Integration Guide](https://erplab.cloud/public/oracle-fusion#external-guide): End-to-end walkthrough — connect, authenticate, list/read/write each supported resource, filter with the `q` grammar, run incremental sync with `LastUpdateDate`, split installments, and recover from errors.
- [Oracle Fusion — Capability matrix](https://erplab.cloud/public/oracle-fusion#capability-matrix): Exhaustive list of supported resources, operations and authentication methods with their support status.
- [Oracle Fusion — Error reference](https://erplab.cloud/public/oracle-fusion#errors): Error envelope shape, status codes, error codes and recovery actions.

## Optional

- [ERPLab public index](https://erplab.cloud/public): List of all published ERP simulators and their documentation.
- [Sign in](https://erplab.cloud/auth): Obtain a tenant environment key and OAuth 2.0 client credentials.
