# Step 2: Verify flow initialization

##

```none
GET {{authPath}}/{{envID}}/flows/{{flowID}}
```

You can use the `GET /{{envID}}/flows/{{flowID}}` endpoint to verify the flow initialization. The response from the authorize request contains the flow ID needed in the request URL. When you run this request, specifying this flow ID, the response returns the initial flow `status`, which is `USERNAME_PASSWORD_REQUIRED`.

##

### Example Request

* cURL

* C#

* Go

* HTTP

* Java

* jQuery

* NodeJS

* Python

* PHP

* Ruby

* Swift

```shell
curl --location --globoff '{{authPath}}/{{envID}}/flows/{{flowID}}'
```

```csharp
var options = new RestClientOptions("{{authPath}}/{{envID}}/flows/{{flowID}}")
{
  MaxTimeout = -1,
};
var client = new RestClient(options);
var request = new RestRequest("", Method.Get);
RestResponse response = await client.ExecuteAsync(request);
Console.WriteLine(response.Content);
```

```golang
package main

import (
  "fmt"
  "net/http"
  "io"
)

func main() {

  url := "{{authPath}}/{{envID}}/flows/{{flowID}}"
  method := "GET"

  client := &http.Client {
  }
  req, err := http.NewRequest(method, url, nil)

  if err != nil {
    fmt.Println(err)
    return
  }
  res, err := client.Do(req)
  if err != nil {
    fmt.Println(err)
    return
  }
  defer res.Body.Close()

  body, err := io.ReadAll(res.Body)
  if err != nil {
    fmt.Println(err)
    return
  }
  fmt.Println(string(body))
}
```

```http
GET /{{envID}}/flows/{{flowID}} HTTP/1.1
Host: {{authPath}}
```

```java
OkHttpClient client = new OkHttpClient().newBuilder()
  .build();

RequestBody body = RequestBody.create(mediaType, "");
Request request = new Request.Builder()
  .url("{{authPath}}/{{envID}}/flows/{{flowID}}")
  .method("GET", body)
  .build();
Response response = client.newCall(request).execute();
```

```javascript
var settings = {
  "url": "{{authPath}}/{{envID}}/flows/{{flowID}}",
  "method": "GET",
  "timeout": 0,
};

$.ajax(settings).done(function (response) {
  console.log(response);
});
```

```javascript
var request = require('request');

  'method': 'GET',
  'url': '{{authPath}}/{{envID}}/flows/{{flowID}}',
  'headers': {
  }
};
request(options, function (error, response) {
  if (error) throw new Error(error);
  console.log(response.body);
});
```

```python
import requests

url = "{{authPath}}/{{envID}}/flows/{{flowID}}"

payload = {}
headers = {

}

response = requests.request("GET", url, headers=headers, data=payload)

print(response.text)
```

```php
<?php
require_once 'HTTP/Request2.php';
$request = new HTTP_Request2();
$request->setUrl('{{authPath}}/{{envID}}/flows/{{flowID}}');
$request->setMethod(HTTP_Request2::METHOD_GET);
$request->setConfig(array(
  'follow_redirects' => TRUE
));
$request->setHeader(array(

try {
  $response = $request->send();
  if ($response->getStatus() == 200) {
    echo $response->getBody();
  }
  else {
    echo 'Unexpected HTTP status: ' . $response->getStatus() . ' ' .
    $response->getReasonPhrase();
  }
}
catch(HTTP_Request2_Exception $e) {
  echo 'Error: ' . $e->getMessage();
}
```

```ruby
require "uri"
require "net/http"

url = URI("{{authPath}}/{{envID}}/flows/{{flowID}}")

http = Net::HTTP.new(url.host, url.port);
request = Net::HTTP::Get.new(url)

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

```swift
var request = URLRequest(url: URL(string: "{{authPath}}/{{envID}}/flows/{{flowID}}")!,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))
    return
  }
  print(String(data: data, encoding: .utf8)!)
}

task.resume()
```
