One browser source per call (two is 422). proxy_country_code or custom_proxy_config answers a cloud-browser login link a human signs in to (result.mode connect). vendor_profile_id answers no link: its browser is found or created and run, the profile's signed-in session births the account (result.mode run: follow get_sender_profile_linkedin_connect_status until bound or failed), or the account gtm-api already holds on it binds at once (result.mode bound). A sender profile that already holds an account gets the re-login link of that account's browser (result.mode relogin; 409 linkedin_browser_missing: detach and connect again). A repeat while a browser is pending reuses it (a new link, never a second browser); on 503 linkedin_connect_unconfirmed call again in a minute, the browser gtm-api made is picked up. Refusals: 422 proxy_pool_empty, vendor_profile_not_found, vendor_profile_no_run_access; 409 linkedin_profile_held_elsewhere, linkedin_profile_busy, linkedin_browser_no_server; 402 linkedin_sender_profiles_full (the plan's LinkedIn sender profiles are all in use) or subscription_required; 403 gtm_scope_missing; 501 while the gtm bridge is unconfigured. Contract: - MCP tool `start_sender_profile_linkedin_connect`, registry package `mcp.unibox/sender_profiles`, mount `unibox.sender-profiles`. - Operation `action`, response envelope `action`. - Flags: none. ## OpenAPI ````yaml /api-reference/unibox/openapi.yaml post /api/sender-profiles/{sid}/linkedin/start-connect openapi: 3.0.3 info: title: 'GetSales public contract: gs.service.unibox' description: >- The team inbox and the AI SDR: every LinkedIn and email thread in one place (conversations, messages, the timeline events), the manual tasks a thread spawns, the sender profiles the team speaks through with their LinkedIn account and mailboxes, and the one agent per team with its scenarios, plans and runs. GENERATED. This document is projected from the Zod MCP tool registry in `product/mcp/gs.mcp` (one tool per public endpoint, 1:1). Do not edit it by hand; edit the tool definition and regenerate with `pnpm openapi:public`. Surface: the public `/api` contract of `gs.service.unibox`, 125 operations. This is the only OpenAPI document the platform publishes. Internal (`/internal`) and health endpoints are deliberately absent: they are not part of any contract, they can change without notice, and the service source is their only description. Conventions: - Auth is a bearer JWT, optionally narrowed by the `Team-SID` header. - Every success body is an MCP envelope: `success: true` plus one typed `operation` shape (`search`, `get`, `create`, `update`, `delete`, `metrics`, `group_by`, `action`), and a `meta` block with `trace_id` for support. - Every failure is the same `McpError` envelope with a code from a fixed 16-code taxonomy, so a client maps errors once. - Lists page with `page_size` (0 to 500, default 50) plus an opaque forward `cursor`; `page_size: 0` returns counts only. - On `GET` and `DELETE`, object-valued query parameters (`filter`, `sort`) travel as JSON text and array-valued ones repeat as `name[]=value`. - The MCP-only `_meta` field (usage analytics) never reaches the backend and is not part of this contract. version: '1.0' contact: name: GetSales url: https://getsales.io email: support@getsales.io license: name: Proprietary url: https://getsales.io/terms servers: - url: https://beta.getsales.io/unibox/v1 description: >- Production (the gateway path on the beta ring; the origin is provisioned per DEPLOY_MAP.md) security: - BearerJwt: [] TeamSid: [] tags: - name: agent_answers description: >- Registry package `mcp.unibox/agent_answers`, served on MCP mount `unibox.knowledge`. - name: agent_conversation_uploads description: >- Registry package `mcp.unibox/agent_conversation_uploads`, served on MCP mount `unibox.agent-memory`. - name: agent_examples description: >- Registry package `mcp.unibox/agent_examples`, served on MCP mount `unibox.agent-memory`. - name: agent_hints description: >- Registry package `mcp.unibox/agent_hints`, served on MCP mount `unibox.agent-memory`. - name: agent_plans description: >- Registry package `mcp.unibox/agent_plans`, served on MCP mount `unibox.agent`. - name: agent_runs description: >- Registry package `mcp.unibox/agent_runs`, served on MCP mount `unibox.agent-memory`. - name: agent_scenarios description: >- Registry package `mcp.unibox/agent_scenarios`, served on MCP mount `unibox.agent`. - name: agent_source_parses description: >- Registry package `mcp.unibox/agent_source_parses`, served on MCP mount `unibox.knowledge`. - name: agent_sources description: >- Registry package `mcp.unibox/agent_sources`, served on MCP mount `unibox.knowledge`. - name: agent_tests description: >- Registry package `mcp.unibox/agent_tests`, served on MCP mount `unibox.agent-memory`. - name: agents description: >- Registry package `mcp.unibox/agents`, served on MCP mount `unibox.website`. - name: conversation_events description: >- Registry package `mcp.unibox/conversation_events`, served on MCP mount `unibox.inbox`. - name: conversations description: >- Registry package `mcp.unibox/conversations`, served on MCP mount `unibox.inbox`. - name: messages description: >- Registry package `mcp.unibox/messages`, served on MCP mount `unibox.inbox`. - name: sender_profiles description: >- Registry package `mcp.unibox/sender_profiles`, served on MCP mount `unibox.sender-profiles`. - name: tasks description: Registry package `mcp.unibox/tasks`, served on MCP mount `unibox.inbox`. - name: timeline description: >- Registry package `mcp.unibox/timeline`, served on MCP mount `unibox.inbox`. paths: /api/sender-profiles/{sid}/linkedin/start-connect: post: tags: - sender_profiles summary: Start a LinkedIn connect for a sender profile description: >- Connect a LinkedIn account to this sender profile: the browser is remembered for 24 hours, so the account it produces binds here instead of birthing a sender profile.
