Environment Variables
As noted in the previous section these are the required environment variables required to successfully deploy.
HEDERA_NETWORK
HEDERA_ACCOUNT_ID
HEDERA_PRIVATE_KEY
API_SECRET_KEY
The HEDERA_ENVIRONMENT is case-insensitive but when lower cased it must map to either, testnet, previewnet or mainnet.
If there is an invalid value the client will automatically throw the error.
Network from environment 'x' could not match for any hedera network. Change your 'HEDERA_NETWORK' environment variable to either: "testnet', 'previewnet' or 'mainnet'
Your scheduled test suite will also expose this configuration issue.
The variables HEDERA_ACCOUNT_ID and HEDERA_PRIVATE_KEY can be found in your hedera account after registration.
The API_SECRET_KEY is securely generated by you and it acts as your authentication key into your REST API.
These variables are completely optional and aren't required but they unlock additional capacity for validating an installation of a client, webhook functionality and security.
API_URL
WEBHOOK_URL
HIDE_STATUS
The API_URL variable is exclusively used by Github Actions to automatically check the status of a deployment, this isn't required to be part of the vercel deployment.
The WEBHOOK_URL variable provides a method for all timestamped consensus responses to be sent to your server, allowing you to set up an asynchronous flow for broadcasting messages and not having to wait for consensus timestamps.
Using an asynchronous consensus flow enables new messages to be broadcast to hedera via your client in the 150-200ms range instead of waiting for the full 3-5 seconds for response finality when processed linearly.
The HIDE_STATUS variable provides the ability to hide the publicly available status screen that describes the state of your deployment, by default this status screen will be displayed.
