### List Projects Example

Source: https://github.com/mittwald/api-client-go/blob/master/README.md

Provides a practical example of using the mittwald API client to list projects. It shows how to construct a request object and iterate over the returned projects.

```go
req := projectclientv2.ListProjectsRequest{
	CustomerID: pointer.To("2ef23459-beb1-4ac2-9a38-d3a9df62bf93"),
	Limit: pointer.To(100),
}

projects, res, err := client.Projects().ListProjects(ctx, req)
for _, project := range projects {
	fmt.Println(project.ShortId)
}
```

### Initialize mittwald API Client (v2)

Source: https://github.com/mittwald/api-client-go/blob/master/README.md

Demonstrates how to initialize the mittwald API client for version 2. It shows setting up a background context and authenticating using an access token retrieved from environment variables.

```go
ctx := context.Background()
token := os.Getenv("MITTWALD_API_TOKEN")

client, err := mittwaldv2.New(ctx, mittwaldv2.WithAccessToken(token))
if err != nil {
	panic(err)
}
```

### Handle API Errors with errors.As

Source: https://github.com/mittwald/api-client-go/blob/master/README.md

Illustrates how to check for specific API error types returned by client calls. It uses Go's errors.As to identify validation errors or other common HTTP errors.

```go
projects, res, err := client.Projects().ListProjects(ctx, req)
if validationError := new(httperr.ErrValidation); errors.As(err, &validationError) {
	// Handle validation error
}
```
