I'm developing a wordpress plugin, which obtains certain product info from the Lightspeed Retail API. I followed the steps in the documentation here http://developers.lightspeedhq.com/retail/authentication/access-token/
I have the Client ID and Client Secret, but I dont have the Temporary Token, I am stuck at this point, I am sure I'm missing some procedure here, can you help me?
This is the current code I use based on the API documentation:
...
$tokenURL = "https://cloud.lightspeedapp.com/oauth/access_token.php";
$postFields = [
'client_id' => 'XXXXXXXXXXXXX',
'client_secret' => 'XXXXXXXXXXXXX',
'code' => 'Temporary Token',
'grant_type' => 'authorization_code'
];
...
