How to Fetch Bearer Token in Magento 2
Magento 2 supports REST API Integration, which lets you speed up getting, sending, and processing data. It also transfers it to the third-party system. Postman is one of the recommended REST clients which connects with Magento 2 API(Application Programming Interface).
Postman is an API testing tool, an API development environment, and a handy HTTP client for testing websites that simplifies API workflow in testing and development.
The bearer token is a cryptic string, usually generated by the server in response to a login request. The Magento access token must be given on the line to allow a web API request from a client. As a result, the token serves as an electronic key that enables you to enter Magento 2 API.
We have to pass an authorized token in the postman while sending API to Magento requested from the postman for security purposes. What if you have the requirement to validate the condition, like if the token is not there, then the condition must be false?
For example, when we forget the password- we use the facility of ‘forget password’ and reset our old password with the new one. In the backend of this process, a temporary token gets generated and passed in the whole process.
In such kind of scenarios, we’ve to use the below method to fetch bearer token in Magento 2.

public function getAuthToken(){ $token = false; $headers = []; foreach ($_SERVER as $name => $value) { if (substr($name, 0, 5) == 'HTTP_') { $headers[str_replace(' ', '-', ucwords(strtolower(str_replace('_', ' ', substr($name, 5)))))] = $value; } } $authorizationBearer = ''; if(isset($headers['Authorization'])) { $authorizationBearer = $headers['Authorization']; } else if(isset($headers['authorization'])) { $authorizationBearer = $headers['authorization']; } else { $authorizationBearer = ""; } $authorizationBearerArr = explode(' ', $authorizationBearer); if( isset($authorizationBearerArr[0]) && trim($authorizationBearerArr[0]) == 'Bearer' && isset($authorizationBearerArr[1]) ){ $token = $authorizationBearerArr[1]; } return $token; } |
