# SDKs

## TypeScript/JavaScript SDK[​](#typescriptjavascript-sdk "Direct link to TypeScript/JavaScript 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" });

```

Secret management

Never hard-code your API key. Store it in an environment variable and read it at runtime:

```typescript
const client = new CredytApiClient({ key: process.env.CREDYT_API_KEY! });

```

Use a `.env` file locally (and add it to `.gitignore`), and inject the variable through your hosting platform's secrets manager in production.

### More TypeScript Examples[​](#more-typescript-examples "Direct link to More TypeScript Examples")

All of the examples in this documentation can also be found in our [GitHub repository](https://github.com/credyt/sdk-ts/tree/main/samples).

## Python SDK[​](#python-sdk "Direct link to Python SDK")

Install the SDK and initialize the client once for all the examples using the Python SDK in this documentation:

```bash
pip install credyt-api

```

```python
def main():
    client = CredytApiClient(
        credential=ServiceKeyCredential(key=os.getenv("CREDYT_API_KEY")),
    )

    response = client.customers.get(
        customer_id="cust_4qh0wajx2n9qtazh2tghzkyan2",
    )
    print(response)


if __name__ == "__main__":
    main()

```
