# Introduction The Quickstart Guide is the fastest way to get hands-on with Credyt and see how everything fits together. It walks you through the core concepts of the platform and gives you a clear, minimal path to start integrating; from creating your first customer to processing real-time usage and tracking wallet balances. We recommend working in test mode throughout this guide. The test environment is completely isolated from production and uses a separate set of API credentials, so you can safely experiment, send usage, and explore payment flows without impacting real customer data.

You can sign up for free at To integrate with Credyt, you’ll need your API key, which must be included in the `X-CREDYT-API-KEY` header in all API requests. API keys are pre-generated for your account during sign-up and can be obtained from the [Credyt App](https://app.credyt.ai). If you’re part of an existing account, contact your account administrator to get access to the API key. When you’re ready to move beyond the basics, explore the [Features](https://docs.credyt.ai/category/features.md) and [Advanced Topics](https://docs.credyt.ai/category/advanced-topics.md) sections for a deeper dive into all of Credyt's capabilities. TypeScript SDK Install the SDK and initialize the client once for all the examples using the TypeScript SDK in this documentation: ```bash npm install @credyt/api-client ``` ```typescript import { CredytApiClient } from "@credyt/api-client"; const client = new CredytApiClient({ key: "YOUR_API_KEY" }); ``` ## Follow along with Bruno[​](#follow-along-with-bruno "Direct link to Follow along with Bruno") With our [Bruno request collections](https://github.com/credyt/learn/tree/main/bruno/credyt-api) you can follow along with the docs interactively and make API requests against your own account.
