Code Samples in Multiple Languages

To help you integrate the NoWallet API seamlessly, we provide code samples in various programming languages. These examples demonstrate how to make a request to the API endpoint and handle the response.

• Shell (cURL): For quick testing and command-line usage.
• HTTP: Raw HTTP request format for understanding the structure.
• JavaScript: Using fetch for browser or Node.js environments.
• Ruby: Using the rest-client library for Ruby applications.
• Python: Using the requests library for Python projects.
• PHP: Using GuzzleHttp for PHP integrations.
• Java: Using HttpURLConnection for Java applications.
• Go: Using the net/http package for Go projects.

Example Request

Below is an example of how to destroy a signature using different languages. Select the tab corresponding to your preferred language to view the implementation.

note

Ensure you replace {access-token} with your actual API token and provide the required request body parameters.

cURL

# Example cURL command to destroy a signature
curl -X POST {baseUrl}/destroy/signature \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json' \
  -H 'Authorization: Bearer {access-token}'

HTTP

POST {baseUrl}/destroy/signature HTTP/1.1

Content-Type: application/json
Accept: application/json

JavaScript

const inputBody = {
  signature: "EXAMPLE-ba325fc6-ca09eb7b4dce",
};
const headers = {
  "Content-Type": "application/json",
  Accept: "application/json",
  Authorization: "Bearer {access-token}",
};

fetch("{baseUrl}/destroy/signature", {
  method: "POST",
  body: inputBody,
  headers: headers,
})
  .then(function (res) {
    return res.json();
  })
  .then(function (body) {
    console.log(body);
  });

Ruby

require 'rest-client'
require 'json'

headers = {
  'Content-Type' => 'application/json',
  'Accept' => 'application/json',
  'Authorization' => 'Bearer {access-token}'
}

result = RestClient.post '{baseUrl}/destroy/signature',
  params: {
  }, headers: headers

p JSON.parse(result)

Python

import requests
headers = {
  'Content-Type': 'application/json',
  'Accept': 'application/json',
  'Authorization': 'Bearer {access-token}'
}

r = requests.post('{baseUrl}/destroy/signature', headers = headers)

print(r.json())

PHP

<?php

require 'vendor/autoload.php';

$headers = array(
    'Content-Type' => 'application/json',
    'Accept' => 'application/json',
    'Authorization' => 'Bearer {access-token}',
);

$client = new \GuzzleHttp\Client();

// Define array of request body.
$request_body = array();

try {
    $response = $client->request('POST','{baseUrl}/destroy/signature', array(
        'headers' => $headers,
        'json' => $request_body,
      )
    );
    print_r($response->getBody()->getContents());
}
catch (\GuzzleHttp\Exception\BadResponseException $e) {
    // handle exception or api errors.
    print_r($e->getMessage());
}

// ...

Java

URL obj = new URL("{baseUrl}/destroy/signature");
HttpURLConnection con = (HttpURLConnection) obj.openConnection();
con.setRequestMethod("POST");
int responseCode = con.getResponseCode();
BufferedReader in = new BufferedReader(
    new InputStreamReader(con.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
    response.append(inputLine);
}
in.close();
System.out.println(response.toString());

Go

package main

import (
      "bytes"
      "net/http"
)

func main() {

    headers := map[string][]string{
        "Content-Type": []string{"application/json"},
        "Accept": []string{"application/json"},
        "Authorization": []string{"Bearer {access-token}"},
    }

    data := bytes.NewBuffer([]byte{jsonReq})
    req, err := http.NewRequest("POST", "{baseUrl}/destroy/signature", data)
    req.Header = headers

    client := &http.Client{}
    resp, err := client.Do(req)
    // ...
}
