ACI.dev Linked Accounts API

Manage end-user Linked Accounts for configured Apps. Initiate an OAuth2 link flow, handle the OAuth2 callback, list and retrieve linked accounts by owner ID, and revoke a Linked Account. White-label OAuth2 is supported so production agents can present the customer's own brand during the consent screen.
ACI.dev Linked Accounts API is one of 4 APIs that ACI.dev publishes on the APIs.io network, described by a machine-readable OpenAPI specification.
This API exposes 1 machine-runnable capability that can be deployed as REST, MCP, or Agent Skill surfaces via Naftiko and 1 JSON Schema definition.
Tagged areas include Linked Accounts, OAuth, and Authentication. The published artifact set on APIs.io includes API documentation, an OpenAPI specification, sample payloads, 1 Naftiko capability spec, and 1 JSON Schema.
