The proxy module is designed as a simple proxy and cache node for Embloy Quicklink. It can be used to integrate Embloy without using a Server-SDK or embedding any code on a third party site, allowing the third party to simple direct to a generic URL which then proxies the Quicklink request by fetching a Request and Client token remotely. The architecture might look like this:

                                                  ┌─────────┐

└───────────────────────┘                     └─► │ Proxy 2 ├──┘
                                                  └─────────┘

The following configuration options are available via environment variables:

• ADMIN_TOKEN: Can be used to authenticate for client tokens. No default value set.
• MAIN_INSTANCE: The url of the main Embloy website. Used to redirect user. No default value set.
• GIN_MODE: The mode in which Gin runs. Can be debug, release, or test. Defaults to debug.
• LOG_DIR: The directory where logs are stored. Defaults to var/log/embloy-proxy.
• LOG_LEVEL: The level of logging. Can be debug, info, warn, error, fatal, or panic. Defaults to info.

To start the proxy service, simply run:

go run cmd/proxy/proxy.go
