Bluecore Transactional API (legacy) is one of 8 APIs that [Bluecore](https://apis.io/providers/bluecore/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Transactional, Email, and Legacy. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, and authentication docs.

The original Bluecore Transactional API on https://api.bluecore.com/email/ - send a transactional or real-time welcome email against a Bluecore campaign, and retrieve the delivery status of a previously triggered send by conversation id. Authenticated by a static customer-specific Bearer API key rather than OAuth. Bluecore's own OpenAPI repository states the company is migrating away from this surface, but the documentation and the specification are both still published with no deprecation notice, no sunset date and no migration guide.
