PBBooking version 4 allows automation of cron job setup using integration with EasyCron. You will need to have an EasyCron account for this to work. You can sign up for EasyCron here: https://www.easycron.com/?ref=83308
Step 1: Log in to your EasyCron account and obtain the API token. You will find this under the API menu when you are logged in to your EasyCron account.
Step 2: Select the options menu from the main PBBooking configuration page. The options menu is accessible by the cog on the top right of the configuration page. From the options menu select the EasyCron tab and then enter your API token into the text box provided.
After entering your token hit Save & Close and then return to the main PBBooking dashboard. Halfway down the main dashboard page is the EasyCron integration for your site.
Select the cron jobs you wish to create and they will automatically be created using the EasyCron REST api. You can configure notification of success and failure through the EasyCron dashboard.
