There are a number of environment variables you can change, these act as your config.
As noted in the previous section these are the required environment variables required to successfully deploy.
The HEDERA_ENVIRONMENT is case-insensitive but when lower cased it must map to either, testnet, previewnet or mainnet.
The API_SECRET_KEY is securely generated by you and it acts as your authentication key into your REST API.
The ENCRYPTION_KEY is a 32 length string acts as your secret for doing any kind of permissioned action in your app while ensuring that private keys don't touch your primary application for storage purposes. For testing you may generate a key with any key generator like this from GCS, however for production it is recommended that you generate it locally.
- Your experience with Blockchain, Hedera, or DLT technology
- The needs of your users, is there dollar value connected to tokens or accounts
- Whether your use of Hedera is primarily for logging and provenence
- Stage of application development, do you need something that is quick to market to test for user feedback?
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.
If you want to use our NFT flow functionality for the complete management of NFT over an API for the creation, minting, metadata generation, and advanced transfer feature you need both the NFT_STORAGE_TOKEN and MIRROR_NODE_URL set.
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.
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.
Information of the current status of the deployment.
