Use this to browse existing return-to-vendor plans. ## OpenAPI ````yaml /openapi.json get /api/supplier-return-plans openapi: 3.0.3 info: contact: email: dev@solya.io name: Solya Team description: >- # Solya API Solya is a fashion retail inventory management platform for buyers and merchandisers. This API exposes all capabilities needed to manage the inventory lifecycle: catalog browsing, risk detection, plan creation (Restock / Markdown / Rebalance), analytics queries, and data-platform operations. ## Authentication Three authentication schemes are supported: | Scheme | Header | Use case | |---|---|---| | **BearerAuth** | `Authorization: Bearer ` | Human users via the Solya web app (NextAuth session) | | **InternalBearerAuth** | `Authorization: Bearer ` | Internal jobs and cron tasks (static token per service) | | **ServiceAccountToken** | `Authorization: Bearer solya_sa_*` | LLM agents and programmatic clients (opaque token created via Settings) | All endpoints except `GET /api/health` require one of the above. See [Agent authentication guide](/docs/api/AGENT_AUTH.md) for the Service Account token flow. ## Response format Every endpoint returns an `ActionResponse` envelope: **Success:** ```json { "success": true, "data": { ... } } ``` **Error:** ```json { "success": false, "errorCode": "PLAN_NOT_FOUND", "error": "Human-readable message" } ``` The `errorCode` is a stable machine-readable string (see common error codes below). The `error` field is for human display only and may change between versions. ## Pagination List endpoints accept `page` (1-indexed, default 1) and `pageSize` (default 20, max 100). Responses include a `total` field with the total number of matching records. ``` GET /api/shops?page=2&pageSize=50 → { "success": true, "data": { "data": [...], "total": 120, "page": 2, "pageSize": 50 } } ``` ## Common error codes | HTTP status | errorCode | Meaning | |---|---|---| | 401 | `UNAUTHORIZED` | Token missing, expired, or invalid | | 403 | `FORBIDDEN` | Token valid but lacks the required permission or scope | | 404 | `NOT_FOUND` | Requested resource does not exist | | 409 | `BUSINESS_RULE_VIOLATION` | Business rule blocked the operation (see response details) | | 422 | `VALIDATION_ERROR` | Input failed Zod schema validation | | 429 | `RATE_LIMIT_EXCEEDED` | Rate limit hit (100 req/min per token) | | 500 | `INTERNAL_ERROR` | Unexpected server error | ## Rate limiting Default limit: **100 requests per minute** per authentication token. When the limit is exceeded the API returns HTTP 429 with `errorCode: "RATE_LIMIT_EXCEEDED"`. Agents should implement exponential back-off and respect the `Retry-After` header when present. ## Further reading See the [Agent guide](/docs/api/AGENT_GUIDE.md) for end-to-end workflows, call-chaining patterns, and anti-patterns to avoid. license: name: Proprietary url: https://solya.app/terms title: Solya API version: 1.0.0 x-ai-context: >- Solya is a fashion retail inventory management platform for retailers. Core concepts: - **Organization** (tenant): every endpoint is scoped by organizationId extracted from the token. - **Shop**: a physical point of sale belonging to the organization. - **ProductVariant**: a SKU — a product variant with size and color. - **Plan**: a Restock / Markdown / Rebalance grouping PlanItems to orchestrate inventory decisions. Typical agent workflow: 1. List the organization's shops — GET /api/shops 2. List variants at risk (stockout, overstock, slow-mover) — GET /api/inventory/risks 3. Create a plan — POST /api/restock-plans, /api/markdown-plans, or /api/rebalance-plans 4. Add items to the plan — POST /api/restock-plans/{planId}/items (or equivalent for other plan types) 5. Validate / submit the plan via the corresponding action endpoint Auth: use a Service Account token (see /docs/api/AGENT_AUTH.md). The token is created by an org admin via Settings and has the format solya_sa_<43 base64url chars>. All responses follow the ActionResponse envelope: - Success: { success: true, data: T } - Error: { success: false, errorCode: string, error: string } Use the errorCode field to drive retry logic or surface user-facing messages. servers: - description: Current environment url: https://app.solya.app security: - BearerAuth: [] tags: - description: >- Health and liveness endpoints.
