+# Dealer Integration Implementation Status
+
+This document summarizes the changes made to integrate the external Royal Enfield Dealer API and implement the dealer validation logic during request creation.
+
+## Completed Work
+
+### 1. External Dealer API Integration
+- **Service**: `DealerExternalService` in `src/services/dealerExternal.service.ts`
+    - Implemented `getDealerByCode` to fetch data from `https://api-uat2.royalenfield.com/DealerMaster`.
+    - Returns real-time GSTIN, Address, and location details.
+- **Controller & Routes**: Integrated under `/api/v1/dealers-external/search/:dealerCode`.
+- **Enrichment**: `DealerService.getDealerByCode` now automatically merges this external data into the system's `DealerInfo`, benefiting PWC and PDF generation services.
+
+### 2. Dealer Validation & Field Mapping Fix
+- **Strategic Mapping**: Based on requirement, all dealer codes are now mapped against the `employeeNumber` field (HR ID) in the `User` model, not `employeeId`.
+- **User Enrichment Service**: `validateDealerUser(dealerCode)` now searches by `employeeNumber`.
+- **SSO Alignment**: `AuthService.ts` now extracts `dealer_code` from the authentication response and persists it to `employeeNumber`.
+- **Dealer Service**: `getDealerByCode` uses jobTitle-based validation against the `User` table as the primary lookup.
+
+### 3. Claim Workflow Integration
+- **Dealer Claim Service**: `createClaimRequest` validates the dealer immediately and overrides approver steps 1 and 4 with the validated user.
+- **Workflow Controller**: Enforces dealer validation for all `DEALER CLAIM` templates and any request containing a `dealerCode`.
+
+### 4. E-Invoice & PDF Alignment
+- **PWC Integration**: `generateSignedInvoice` now uses the enriched `DealerInfo` containing the correct external GSTIN and state code.
+- **Invoice PDF**: `PdfService` correctly displays the external dealer name, GSTIN, and POS from the source of truth.
+
+## Conclusion
+All integrated components have been verified via test scripts and end-to-end flow analysis. The dependency on the local `dealers` table has been successfully minimized, and the system now relies on the `User` table and External API as the primary sources of dealer information.
