```

```php
<?php

response = http.request(request)
puts response.read_body
```

```swift
var request = URLRequest(url: URL(string: "{{customDomain}}/.well-known/did.json")!,timeoutInterval: Double.infinity)
request.httpMethod = "GET"

let task = URLSession.shared.dataTask(with: request) { data, response, error in
  guard let data = data else {
    print(String(describing: error))
