Sonatype Central Portal Publisher API

This page is part of the official Central Repository documentation and focuses specifically on publishing artifacts through the Portal Publisher API instead of the web UI. It is aimed at developers and release engineers who want to automate the path from a built artifact to Maven Central.

The content walks through the full API workflow: generating and using a Portal token for authentication and authorization, uploading a deployment bundle, verifying the status of that deployment, and then publishing or dropping it. A separate section covers manually testing a deployment bundle, and the navigation links out to Maven, Gradle, and OSSRH staging alternatives.

It fits build and platform engineers maintaining release pipelines, especially those wiring publishing into CI jobs where a browser-based upload is impractical. Teams migrating from the legacy OSSRH staging API will also find it useful for mapping old steps onto the newer portal endpoints.

Read the Getting Started and token-generation pages first, then keep this reference open while implementing calls. Treat the publish and drop actions as irreversible checkpoints and test with a bundle before releasing. In short, it is the authoritative endpoint reference for automated Maven Central releases.
