Reading messages through the public API never marks them as read. ## OpenAPI ````yaml /openapi.json get /v1/conversations/{conversation_id}/messages openapi: 3.1.0 info: title: YV Business API description: >- Public API for YaVendio merchants to access orders, product catalog, conversations, contacts and company profile, and to send WhatsApp template messages. ## Authentication All endpoints require a valid API key sent via the `X-API-Key` header. API keys are created and managed from the [YaVendio Dashboard](https://ya.onl) under **Settings → API Keys**. Use the **Authorize** button above to set your key for all requests. Every endpoint declares the scope it requires (e.g. `orders:read`, `products:write`, `conversations:read`, `contacts:read`, `company:read`, `outbound:send`, `outbound:read`), listed on its reference page. Keys created from the dashboard today carry no scopes and therefore have full access; a key that has scopes but lacks the one an endpoint requires gets `403 Forbidden`. ## Rate Limiting Requests are rate-limited per merchant. Every response includes `X-RateLimit-Limit`, `X-RateLimit-Remaining`, and `X-RateLimit-Reset` headers. Check these headers to know your current limit and remaining quota. When the limit is exceeded, the API responds with `429 Too Many Requests` and adds a `Retry-After` header. ## Pagination List endpoints support pagination via `page` and `limit` query parameters. Responses include a `pagination` object with `total_pages`, `total_items`, and `has_more` fields. Maximum `limit` is 100. version: 1.14.2 servers: - url: https://api.ya.onl security: [] tags: - name: Orders description: Retrieve merchant orders and their details. - name: Products description: CRUD operations on merchant products. - name: Product Variants description: Manage variants of a product. - name: Product Options description: Manage product options. - name: Product Option Values description: Manage individual option values. - name: Product Media description: Manage media files attached to product variants. - name: Categories description: CRUD operations on merchant categories (tags). - name: Product Categories description: Assign and remove categories from products. - name: Catalogs description: Retrieve merchant catalogs. - name: Webhooks description: Manage webhook subscriptions for real-time order events. - name: Conversations description: Read WhatsApp conversations and their messages. - name: Contacts description: Retrieve campaign contacts. - name: Company description: Retrieve the merchant's company profile. - name: Templates description: >- List the WhatsApp templates approved for the merchant, with the variables each one expects. - name: Template Messages description: >- Send approved WhatsApp templates to customers and follow their delivery status. paths: /v1/conversations/{conversation_id}/messages: get: tags: - Conversations summary: List messages of a conversation description: |- Retrieve the messages of a conversation, newest page first.
