GCP Function to securely proxy API calls to Alpaca Broker API, including Plaid and Stytch.

The repo is intended to simplify development of mobile / web apps on top Alpaca.

All calls abbreviated by /alpaca will be forwarded to Alpaca, using the predefined Alpaca.Markets Broker API base URL.

All calls abbreviated by /plaid will be forwarded to Plaid.

All calls abbreviated by /stytch will be forwarded to Stych.

The proxy function can log requests & responses (based on the DEBUG environment variable)

The function uses security best practices to ensure compliance and security of Alpaca credentials.

The project is deployed using GCP Cloud Build. The deployment will create a proxy end-point. It is suggested to set up a deployment trigger in CloudBuild.
