Polar API & SDK

You can integrate Polar on your docs, sites or services using our Public API, Webhook API, and/or our Polar JS SDK (Beta)

Contributions

You can develop on Polar in GitHub Codespaces. The environment is pre-configured to contain (most) of the tools that you'll need, and will help you to configure the integration between Polar and GitHub (see .devcontainer/README). Using an instance with at least 4 cores is recommended.

You can also develop on Polar locally on your computer, which is the recommended way of working if you want to get into the deep of how Polar works. Documentation on how to setup a development environment is incoming. Until then, if you're feeling adventurous checkout our repository structure below and clients/README and server/README in particular.
