Vessel Platform API is one of 20 APIs that [Vessel](https://apis.io/providers/vessel/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Authentication, Connections, Integration, Passthrough, and Platform. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, an API reference, and a GitHub repository.

The Vessel Platform API is the control plane of the Vessel embedded integrations platform. It covers the Link authentication handshake (session tokens and access tokens), the catalog of supported integrations, connection lifecycle (list, find, delete), customer-managed OAuth apps, the /api/passthrough escape hatch for calling a downstream provider's native API directly, and webhook subscription management. Every request is authenticated with an x-vessel-api-token header. Published by Vessel as OpenAPI 3.1.0 with 15 operations.
