Platform.sh Project API is one of 60 APIs that [Platform.sh](https://apis.io/providers/platform.sh/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Project. The published artifact set on APIs.io includes an OpenAPI specification, authentication docs, rate-limit docs, and API documentation.

## Project Overview On Upsun, a Project is backed by a single Git repository and encompasses your entire application stack, the services used by your application, the application's data storage, the production and staging environments, and the backups of those environments. When you create a new project, you start with a single [Environment](#tag/Environment) called *Master*, corresponding to the master branch in the Git repository of the project—this will be your production environment. If you connect your project to an external Git repo using one of our [Third-Party Integrations](#tag/Third-Party-Integrations) a new development environment can be created for each branch or pull request created in the repository. When a new development environment is created, the production environment's data will be cloned on-the-fly, giving you an isolated, production-ready test environment. This set of API endpoints can be used to retrieve a list of projects associated with an API key, as well as create and update the parameters of existing projects. > **Note**: > > To list projects or to create a new project, use [`/subscriptions`](#tag/Subscriptions).
