11 · BACKEND — Phase 1 API Reference (Inventory & Supply Chain)

Authoritative for: the REST API contract — every endpoint with complete request/response bodies, the error catalog, and enums. Navigation: you arrived from 00-CORE.md. Business rules, architecture, and the entity model are in 10-BACKEND-PHASE1.md. Frontend consumers follow 20-FRONTEND.md. Record work in Backend/PROGRESS.md. Consistency: field names match the entity model in 10-BACKEND-PHASE1.md Part C. This document should match the Swashbuckle-generated OpenAPI; an OpenAPI 3.1 YAML can be produced from it.

1. Conventions

1.1 Base URL & versioning

https://{host}/api/v1

Path-based versioning. Breaking changes bump the major version.

1.2 Authentication & authorization

Authorization: Bearer <access_token>

Every endpoint requires a valid Bearer JWT; unauthenticated → 401. Tokens are issued by the external AuthHex IdP (not ERPCore) — RS256, issuer AuthHex, audience AuthHexClient. ERPCore validates them against AuthHex's static RSA public key (no JWKS) and admits only holders of the configured ERP UserType/Role (door policy) → otherwise 403.
Per-endpoint RBAC is NOT enforced in Phase 1 (FR-X-01): any ERP-admitted user may call any endpoint.
The audit actor is AuthHex's custom UserId (GUID) claim, mapped to a local shadow user (int). Clients never send createdBy; the server derives it (docs/10 A.4).

1.3 Content type & encoding

application/json, UTF-8, camelCase. Timestamps ISO 8601 UTC (2026-07-07T09:30:00Z); dates YYYY-MM-DD. Base currency LKR in Phase 1.

1.4 List envelope

{ "items": [ /* ... */ ],
  "pagination": { "page": 1, "pageSize": 20, "totalItems": 137, "totalPages": 7 } }

1.5 Pagination / filtering / sorting

page (1-based, default 1) · pageSize (default 20, max 200) · sort (name / -createdAt) · q (free text) · resource filters documented per endpoint.

1.6 Concurrency & idempotency

Mutable resources expose ETag (EF RowVersion); PUT/PATCH send If-Match → 412 on mismatch. Transactional POSTs (GRN confirm, transfer dispatch/receive, adjustment) accept an optional Idempotency-Key header.

1.7 Status codes

200 read/update · 201 created (+Location) · 204 no content · 400 validation · 401 unauth · 404 not found · 409 domain conflict · 412 ETag mismatch · 422 semantically invalid.

1.8 Error format (RFC 7807)

{ "type": "https://errors.erp.local/validation",
  "title": "One or more validation errors occurred.",
  "status": 400, "traceId": "00-6f1c...-01",
  "errors": { "sku": ["The sku field is required."], "lines": ["At least one line is required."] } }

Domain errors add a stable code (catalog §7):

{ "type": "https://errors.erp.local/insufficient-stock",
  "title": "Insufficient stock to fulfil the issue.",
  "status": 409, "code": "STOCK_NEGATIVE_BLOCKED",
  "detail": "Available 4 < requested 10 for item ITM-1001 at WH-MAIN.", "traceId": "00-9a2f...-01" }

2. Master Data

2.0 Auth — external (AuthHex IdP); not an ERPCore endpoint

Superseded (2026-07-14). ERPCore no longer exposes /auth/login. Login, registration and recovery are owned by the separate AuthHex service (e.g. POST /api/loginUser with { identifier, password }), which returns an RS256 JWT (issuer AuthHex, audience AuthHexClient; claims UserId (GUID), UserTypeCode, RoleCode, NIC, …). ERPCore only validates that Bearer token and provisions a local shadow user (docs/10 A.4). The old shape is retained here for history:

POST {AuthHex}/api/loginUser   →   { "identifier": "…", "password": "••••••••" }
// 200 → an RS256 access token (Bearer). Bad credentials → 401. Token → ERPCore Authorization: Bearer <token>.

2.1 Items

`GET /items`

Query: q, status (Active|Inactive), categoryId, trackingMode (None|Batch|Serial), + paging. 200 OK

{ "items": [ { "itemId": 1001, "sku": "ITM-1001", "name": "Steel Bolt M8x40",
      "categoryId": 12, "baseUomId": 1, "defaultVendorId": 5,
      "itemType": "Stocked", "trackingMode": "Batch", "taxClass": "STD", "status": "Active" } ],
  "pagination": { "page": 1, "pageSize": 20, "totalItems": 1, "totalPages": 1 } }

`GET /items/{itemId}` → 200 OK (header `ETag: "AAAAAAAAB9E="`)

{ "itemId": 1001, "sku": "ITM-1001", "name": "Steel Bolt M8x40",
  "description": "Grade 8.8 zinc-plated hex bolt", "categoryId": 12, "baseUomId": 1,
  "defaultVendorId": 5, "itemType": "Stocked", "trackingMode": "Batch", "taxClass": "STD",
  "status": "Active", "reorder": [ { "warehouseId": 1, "reorderPoint": 500, "reorderQty": 2000 } ],
  "createdAt": "2026-06-01T08:00:00Z", "updatedAt": "2026-07-01T10:15:00Z" }

`POST /items`

{ "sku": "ITM-1002", "name": "Steel Nut M8", "description": "Grade 8 zinc-plated hex nut",
  "categoryId": 12, "baseUomId": 1, "defaultVendorId": 5,
  "itemType": "Stocked", "trackingMode": "None", "taxClass": "STD" }

201 Created — Location: /api/v1/items/1002

{ "itemId": 1002, "sku": "ITM-1002", "name": "Steel Nut M8", "categoryId": 12, "baseUomId": 1,

  "status": "Active", "createdAt": "2026-07-07T09:30:00Z" }

400 → code: SKU_DUPLICATE if SKU exists.

`PUT /items/{itemId}`

Full update; requires If-Match. → 200 OK updated resource; 412 on ETag mismatch.

`PATCH /items/{itemId}/status`

{ "status": "Inactive" }

204 No Content. Masters are deactivated, not hard-deleted (FR-MD-08); hard DELETE of a referenced master → 409 MASTER_IN_USE.

`PUT /items/{itemId}/reorder`

{ "settings": [ { "warehouseId": 1, "reorderPoint": 500, "reorderQty": 2000 },
                { "warehouseId": 2, "reorderPoint": 100, "reorderQty": 400 } ] }

  "ledgerRefs": [ 55021 ] }

409 STOCK_NEGATIVE_BLOCKED if return qty exceeds available.

4. Goods Receipt (GRN)

On confirm, each line creates a FIFO cost layer and posts an inbound ledger entry (FR-GRN-06). Goods may land holdStatus: "OnHold" (not issuable) until released.

4.1 `POST /grns`

Against a PO (lines default from open PO lines) or direct (poId: null, by permission).

{ "poId": 342, "warehouseId": 1,

422 OVER_RECEIPT_TOLERANCE if qty exceeds open PO qty beyond tolerance.

4.2 `POST /grns/{grnId}/confirm`

Header: optional Idempotency-Key. 200 OK — creates FIFO layers + ledger; updates PO line qtyReceived.

{ "grnId": 780, "status": "Confirmed", "postedAt": "2026-07-07T10:05:00Z",
  "createdLayers": [ { "layerId": 9001, "itemId": 1001, "warehouseId": 1, "batchId": 410,
      "qtyReceived": 5000, "qtyRemaining": 5000, "unitCost": 12.50, "receiptDate": "2026-07-07T10:05:00Z" } ],

200 OK → { "grnLineId": 1300, "holdStatus": "Available" } action: "Reject" moves the quantity to a return workflow instead.

5. Stock Management

5.1 `GET /stock/on-hand?itemId=1001&warehouseId=1`

{ "itemId": 1001, "warehouseId": 1, "onHand": 5000, "available": 0, "onHold": 5000,
  "inTransit": 0, "reserved": 0, "asOf": "2026-07-07T10:06:00Z" }

available = onHand − onHold − reserved − inTransit(out). reserved always 0 in Phase 1 (stub, FR-STK-11).

5.2 `GET /stock/ledger?itemId=1001&warehouseId=1&from=2026-07-01&to=2026-07-07`

{ "items": [ { "ledgerId": 55010, "itemId": 1001, "warehouseId": 1, "binId": 45, "batchId": 410,
      "serialId": null, "direction": "In", "qtyBase": 5000, "unitCost": 12.50, "value": 62500.00,
      "runningBalance": 5000, "sourceDocType": "GRN", "sourceDocId": 780, "userId": 17,
      "createdAt": "2026-07-07T10:05:00Z" } ],
  "pagination": { "page": 1, "pageSize": 20, "totalItems": 1, "totalPages": 1 } }

5.3 `GET /stock/valuation?itemId=1001&warehouseId=1`

{ "itemId": 1001, "warehouseId": 1,
  "layers": [ { "layerId": 9001, "qtyRemaining": 5000, "unitCost": 12.50, "value": 62500.00,
      "receiptDate": "2026-07-07T10:05:00Z" } ],
  "totalQty": 5000, "totalValue": 62500.00, "currency": "LKR", "costingMethod": "FIFO" }

5.4 Transfers (in-transit)

create → dispatch → receive. Dispatch consumes source FIFO layers into in-transit; receive creates the destination layer at inherited cost (cost-preserving, FR-STK-06).

`POST /stock-transfers`

{ "srcWarehouseId": 1, "destWarehouseId": 2,
  "lines": [ { "itemId": 1001, "srcBinId": 45, "destBinId": 90, "batchId": 410, "qty": 1000 } ] }

201 Created

{ "transferId": 55, "docNo": "TRF-2026-00055", "srcWarehouseId": 1, "destWarehouseId": 2,
  "status": "Draft",
  "lines": [ { "transferLineId": 300, "itemId": 1001, "srcBinId": 45, "destBinId": 90, "batchId": 410, "qty": 1000 } ] }

`POST /stock-transfers/{id}/dispatch` → 200 OK (status `InTransit`)

{ "transferId": 55, "status": "InTransit",
  "consumedLayers": [ { "layerId": 9001, "qtyConsumed": 1000, "unitCost": 12.50 } ],
  "ledgerRefs": [ 55033 ] }

409 STOCK_NEGATIVE_BLOCKED if source available < requested.

`POST /stock-transfers/{id}/receive`

{ "lines": [ { "transferLineId": 300, "qty": 1000 } ] }

200 OK (status Received)

{ "transferId": 55, "status": "Received",
  "createdLayers": [ { "layerId": 9040, "warehouseId": 2, "qtyReceived": 1000, "unitCost": 12.50 } ],
  "ledgerRefs": [ 55034 ] }

5.5 Adjustments (auto-post)

Reason code mandatory. Decrease consumes FIFO layers; increase creates a layer at supplied/last cost (FR-STK-07).

`POST /stock-adjustments`

{ "warehouseId": 1, "reasonCodeId": 4,
  "lines": [ { "itemId": 1001, "binId": 45, "batchId": 410, "qtyDelta": -15 } ] }

201 Created

{ "adjustmentId": 77, "docNo": "ADJ-2026-00077", "warehouseId": 1, "reasonCodeId": 4,
  "status": "Posted", "createdBy": 17, "createdAt": "2026-07-07T10:20:00Z",
  "lines": [ { "adjLineId": 210, "itemId": 1001, "binId": 45, "batchId": 410, "qtyDelta": -15 } ],
  "ledgerRefs": [ 55050 ] }

400 REASON_CODE_REQUIRED if reasonCodeId omitted.

5.6 Counts

`POST /stock-counts`

{ "warehouseId": 1, "countType": "Cycle", "itemIds": [1001, 1002] }

201 Created — status Draft, system quantities snapshotted

{ "countId": 30, "docNo": "CNT-2026-00030", "warehouseId": 1, "countType": "Cycle", "status": "Draft",
  "lines": [ { "countLineId": 400, "itemId": 1001, "binId": 45, "systemQty": 4985, "countedQty": null, "variance": null } ] }

`PUT /stock-counts/{id}/counts`

{ "lines": [ { "countLineId": 400, "countedQty": 4980 } ] }

200 OK → { "lines": [ { "countLineId": 400, "systemQty": 4985, "countedQty": 4980, "variance": -5 } ] }

`POST /stock-counts/{id}/post` → 200 OK (posts variance adjustment, closes count)

{ "countId": 30, "status": "Posted", "adjustmentId": 78, "ledgerRefs": [ 55060 ] }

5.7 Reorder alerts

`GET /stock/reorder-alerts?warehouseId=1`

Items at/below ROP (FR-STK-10); computed on read, no stored entity.

{ "items": [ { "itemId": 1002, "warehouseId": 1, "available": 90, "reorderPoint": 100,
      "reorderQty": 400, "suggestedRequisitionQty": 400 } ],
  "pagination": { "page": 1, "pageSize": 20, "totalItems": 1, "totalPages": 1 } }

POST /stock/reorder-alerts/{itemId}/requisition?warehouseId=1 → creates a draft requisition for the suggested qty.

6. Reference Data

`GET /reason-codes?context=Adjustment`

{ "items": [ { "reasonCodeId": 4, "code": "DMG", "description": "Damage", "context": "Adjustment" },
             { "reasonCodeId": 22, "code": "QREJ", "description": "Quality Reject", "context": "Return" } ],
  "pagination": { "page": 1, "pageSize": 20, "totalItems": 2, "totalPages": 1 } }

POST /reason-codes (admin). Number sequences are server-managed; no write API in Phase 1.

7. Domain Error Catalog

9. Implementation notes (ASP.NET Core)

Serve via Swashbuckle; annotate controllers with [ProducesResponseType] per status so generated OpenAPI matches this document.
Use ProblemDetails / ValidationProblemDetails for all errors (§1.8) — framework default.
Map ETag/If-Match to EF [Timestamp] byte[] RowVersion.
Wrap every stock-affecting operation (GRN confirm, transfer dispatch/receive, adjustment, return, count post) in one UoW transaction; FIFO layer consumption locks affected layer rows (NFR-02). See 10-BACKEND-PHASE1.md Part A.
Derive audit actor from User.FindFirst("sub"), never from the body.
Deferred (Phase 2+): vendor invoice + 3-way match, reservation/allocation, RBAC policy attributes — all additive, no breaking change to these routes.

End of 11-BACKEND-PHASE1.md. Model & rules: 10-BACKEND-PHASE1.md. Record work: Backend/PROGRESS.md.
