  Vessel is a developer-first embedded integrations platform that enables
  product teams to add native integrations to their applications. It provides
  unified API abstractions, actions APIs, and passthrough APIs to connect with
  CRM, sales engagement, marketing automation, chat, and dialer tools while
  managing authentication, rate limits, and data normalization. The platform
  supports OAuth and API-key authentication via a drop-in React UI component
  (Vessel Link), with two API surfaces: api.vessel.dev for the newer GTM
  integrations platform and api.vessel.land for the CRM-focused platform.

      The Vessel Platform API (api.vessel.dev) provides the core integration
      platform capabilities including authentication session management, access
      token exchange, connection lifecycle management, integration listing,
      passthrough API calls, and webhook management. Authentication uses the
      x-vessel-api-token header for server-side requests plus x-vessel-access-token
      for user connection scoped operations.

      The Vessel Actions API provides pre-built, validated actions for common
      integration operations across CRM, sales engagement, marketing automation,
      chat, and dialer systems. Actions validate API responses and request inputs,
      standardize data types (ISO dates, string IDs), and abstract downstream
      provider quirks.
