# Veza > Veza is an identity security platform. Its Open Authorization API (OAA) lets > you publish identity, resource, and authorization metadata from custom or > unsupported applications into the Veza Entity Catalog, making them searchable > and governable alongside natively supported integrations. Authentication is a > per-tenant API key sent as a bearer token; all calls target the customer's own > Veza tenant host (https://.vezacloud.com). ## Developer - [Veza Developers](https://developer.veza.com/): Open Authorization API documentation. - [Getting Started](https://developer.veza.com/oaa/guide/getting-started.html) - [Quickstart](https://developer.veza.com/oaa/guide/quickstarts.html) - [OAA Push API Reference](https://developer.veza.com/oaa/reference/api/oaa-push-api.html) - [Example Connectors](https://developer.veza.com/oaa/guide/examples.html) ## SDKs & CLI - [Python SDK (oaaclient)](https://pypi.org/project/oaaclient/) — `pip install oaaclient` (github.com/veza/oaaclient-py).
