A lead's `status` holds a stage `key`, and tenants rename and reorder their stages freely. ## OpenAPI ````yaml /openapi/public-api.yaml get /v1/lead-stages openapi: 3.1.0 info: title: Linkiasoft API version: 1.0.0 description: > Send and read messages across WhatsApp, Instagram, Messenger and Telegram, and read and update the CRM behind them — leads, pipeline stages, company contacts and activity history. Every endpoint is authenticated with a tenant-scoped API key and returns only data belonging to that key's workspace. **Two hosts, one key.** Messaging lives on `social.linkiasoft.com` and the CRM on `api.linkiasoft.com`. Each endpoint below shows its own base URL; the same API key authenticates against both. servers: - url: https://social.linkiasoft.com/api description: Production security: - apiKey: [] tenantId: [] tags: - name: Conversations description: Read threads and send messages. - name: Templates description: Approved WhatsApp message templates. - name: Channels description: The connected accounts you can send from. - name: Leads description: Deals moving through your pipeline. - name: Pipeline description: The stages a lead can sit in. - name: Contacts description: People attached to a company. - name: Activities description: Logged calls, emails, meetings and follow-ups. - name: Customers description: The companies and accounts your contacts belong to. - name: Tags description: Labels applied to customers, contacts and leads. - name: Quick replies description: Team-shared canned responses. - name: WhatsApp groups description: Create and manage WhatsApp group chats. paths: /v1/lead-stages: servers: - url: https://api.linkiasoft.com/api get: tags: - Pipeline summary: List pipeline stages description: > Read this before writing any integration that moves leads.

Create one in **Settings → API Keys**; the plaintext value is shown once and never again. Keys are scoped. A key needs `conversations:send` to send, `conversations:read` to read threads and messages, `templates:read` to list templates, and `channels:read` to list channels. A key missing the scope for an endpoint gets `403`. The CRM endpoints use the same `resource:action` form: `leads:read`, `leads:create`, `leads:update`, `leads:delete`, `customers:read`, `customers:create`, `customers:update`, `customers:delete`, `customers:manage`. Several resources have no scope of their own and borrow one: | Resource | Governed by | |---|---| | Contacts | `customers:*` | | Activities | `customers:*` for customer activities, `leads:*` for lead activities | | Tags | `customers:read` to list, `customers:manage` to change | | Pipeline stages | `leads:*` | | Quick replies | `quick-replies:read` / `quick-replies:write` | | WhatsApp groups | `wa-groups:manage` | Grant only what the integration needs — a key that only sends notifications should hold `conversations:send` and nothing else. tenantId: type: apiKey in: header name: X-Tenant-Id description: > Your workspace UUID. Required on every request **in addition to** `x-api-key`. It does not select the workspace — data access is always scoped to the workspace that owns the API key, and a mismatched value cannot read anyone else's data. ````
