# Configure and Run the Application

### Configure the application

The application configuration files are present under the [`config`](https://github.com/juspay/hyperswitch/blob/main/config) directory.

The configuration file read varies with the environment:

* Development: [`config/development.toml`](https://github.com/juspay/hyperswitch/blob/main/config/development.toml)
* Sandbox: `config/sandbox.toml`
* Production: `config/production.toml`

Refer to [`config.example.toml`](https://github.com/juspay/hyperswitch/blob/main/config/config.example.toml) for all the available configuration options. Refer to [`development.toml`](https://github.com/juspay/hyperswitch/blob/main/config/development.toml) for the recommended defaults for local development.

Ensure to update the [`development.toml`](https://github.com/juspay/hyperswitch/blob/main/config/development.toml) file if you opted to use different database credentials as compared to the sample ones included in this guide.

Once you're done with configuring the application, proceed with [running the application](#run-the-application).

#### Run the application

1. Compile and run the application using `cargo`:

   ```bash
   cargo run
   ```

   If you are using `nix`, you can compile and run the application using `nix`:

   ```bash
   nix run
   ```
2. Verify that the server is up and running by hitting the health endpoint:

   ```bash
   curl --head --request GET 'http://localhost:8080/health'
   ```

   If the command returned a `200 OK` status code, proceed with trying out our APIs.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.hyperswitch.io/self-hosting/hyperswitch-open-source/readme-1/local-setup-using-individual-components/set-up-hyperswitch-backend/configure-and-run-the-application.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
