How to create access token for Magento 2 Rest api programmatically?

For Access Magento 2 REST API, you need to first generate an access token. Access token used for synchronization with Magento to another third-party platform.

Without Access token, you can’t communicate with Magento 2. For Create access token you need to call POST action with Request payload. Your request URL will be rest/V1/integration/admin/token append to your site URL.

Pass Username and password in request body of Magento backend to generate the Access token.

<?php
$url = "http://127.0.0.1/magento2/index.php/rest";
$token_url = $url."/V1/integration/admin/token";
$username = "admin";
$password = "admin123";

//Authentication rest API magento2, For get access token
$ch = curl_init();
$data = array("username" => $username, "password" => $password);
$data_string = json_encode($data);

$ch = curl_init();
curl_setopt($ch,CURLOPT_URL, $token_url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
$token = curl_exec($ch);
$accessToken = json_decode($token);
echo $accessToken;

<?php

$url = "http://127.0.0.1/magento2/index.php/rest";

$token_url = $url."/V1/integration/admin/token";

$username = "admin";

$password = "admin123";

//Authentication rest API magento2, For get access token

$ch = curl_init();

$data = array("username" => $username, "password" => $password);

$data_string = json_encode($data);

$ch = curl_init();

curl_setopt($ch,CURLOPT_URL, $token_url);

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");

curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));

$token = curl_exec($ch);

$accessToken = json_decode($token);

echo $accessToken;

After successfully call with Magento 2, You can get response as a string with Access Token. You can use access token with any Magento 2 REST API call with “Bearer $accessToken”

Output:
qhkk60btde5681tfvvhd921sw2051t02

You can Use the token in a Web API request as below,
Authorization: Bearer <access token>
Where Replace <access token> token with your actual access token.
