Login Screen

Hydra. Check-in app

Overview

The login screen is used to connect the Hydra Check-in App to a Hydra Bridge installation.

The app requires two inputs:

a site URL
a GATE key

There are no user accounts or credentials involved. Access is controlled entirely through the GATE key.

Site

The Site field expects the full URL of the website where the Hydra Bridge plugin is installed.

Examples:

https://yourdomain.com
https://events.yoursite.com

The app uses this URL to send requests to the Bridge plugin and establish a connection.

If the URL is invalid, unreachable, or Hydra Bridge is not available on that site, the connection will fail.

GATE key

The GATE key is generated within the Hydra Bridge plugin.

It defines:

which events are accessible
which attendees can be loaded
which check-ins are allowed

Each GATE key represents a specific access scope. Different keys can be created for different use cases (e.g. different entry points or teams).

If the GATE key is invalid or does not match the specified site, authentication will fail.

Connect

The Connect button initiates the connection process.

After entering the Site and GATE key, the app sends a handshake request to the Hydra Bridge.

If successful:

the connection is validated
available events are retrieved
the app proceeds to the next screen

If unsuccessful:

an error message is returned
no data is loaded

Settings

The Settings option, located below the Connect button, opens the Settings screen.

This screen contains configuration options that are available before login. Some settings are only accessible after a successful connection and will not be visible at this stage.
