 > Because I've experienced problems getting the sessionid from the CRM when multiple users are accessing the CRM at the same time, the solution was to store the sessionid into a file within Laravel application.
 > Instead of getting the token from the database for each request using the webservice API, a check is made against the expiry time in the file. If the expiry time has expired, a token is requested from the CRM and file is updated with the new token and updated expiry time.
