Using this SDK

This tutorial will walk you through the basics of creating a project that uses the Changelly Fiat API SDK.

1. First, run the following command to create a default package.json file:

> npm init --y

2. If you choose to use TypeScript, you can now add TypeScript features to this project. The following steps will install TypeScript, create a tsconfig.json file, and gain access to most built-in types for NodeJS:

> npm install typescript
> npx tsc --init
> npm install -D @types/node

3. Add the Changelly Fiat API SDK to your project via Node Package Manager:

> npm install @changelly/fiat-api-sdk-node

4. Set your API keys to an environment variable such as CHANGELLY_PRIVATE_KEY and CHANGELLY_PUBLIC_KEY so that it will not be committed to source control.
5. Create a basic index.ts file for your project that creates a Changelly Fiat API client:

import { ChangellyFiatClient } from "@changelly/fiat-api-sdk-node";

const client = new ChangellyFiatClient({
  privateKey: process.env["CHANGELLY_PRIVATE_KEY"],
  publicKey: process.env["CHANGELLY_PUBLIC_KEY"],
});

6. Make an API call and check the result:

const providers = await client.getProviderList();

console.log({ providers });
