Sequin Postgres Databases API

info:
  title: Sequin Management Backfills Postgres Databases API
  description: The Sequin Management API configures and operates a Sequin Postgres change data capture (CDC) deployment programmatically. Sequin is open source and self-hostable, and also runs as Sequin Cloud. Most resources can be defined declaratively in a sequin.yaml file; this API exposes the same resources - Postgres database connections (sources), sink consumers (destinations), HTTP endpoints, and backfills - over REST. The Sequin Stream sink also exposes an HTTP pull consumption surface (receive / ack / nack). All requests require a Bearer token found in the Sequin console under "Manage account". Not all Sequin resources are available in the Management API.
