Halfords send the LoC to the employee via email As soon as the application is approved.
Please note that all emails are sent to the email address the employee has used to make their application and some employees forget they may have used their personal email instead of the work email.
The process is instant because it's automatic - RG sends information to Halfords as soon as an application is approved via API, and the API triggers a command which automatically sends the LoC. Please note that the approval period is longer for clients on post-approval, because an administrator needs to go and manually approve the application in the Reward Manager.
