I am trying to embed square payment method to my site through its documentation given in the link below. https://docs.connect.squareup.com/articles/processing-payment-php/
After receiving nonce, I am trying to get the location id as defined in the documentation. In console it always returns the following error:
Fatal error: Uncaught exception 'SquareConnect\ApiException' with message 'API call to https://connect.squareup.com/v2/locations failed: SSL certificate problem: unable to get local issuer certificate' in C:\xampp\htdocs\my_project\vendor\square\connect\lib\ApiClient.php:245
