Test Your Integration on a Testnet Using a Sandbox API Key

To test your integration, you can leverage a Halliday sandbox API key to create accounts and issue transactions on a test network like Goerli, Sepolia, Polygon Mumbai, Arbitrum Goerli, and more.

To route all of the SDK requests to the Halliday sandbox servers, be sure to set sandbox = true. Be sure to also specify a testnet BlockchainType for transactions to not spend actual funds.

Here's an example:

import {Halliday, BlockchainType} from "halliday-sdk";

// Initialize the Halliday client.
const hallidayClient = new Halliday(
    "<YOUR_API_KEY>",
    BlockchainType.OPTIMISM_GOERLI,        // Specifying blockchainType is optional - defaults to Mumbai
    true                                   // This is an optional argument that makes the SDK interact with our sandbox environment
);

The last argument sets the Halliday client to sandbox mode. The constructor has the following parameters:

All subsequent account creations and transactions will now occur on test networks
